the programmer is a write-only machine, the assumption being that, if you're pro-gramming the device, you already have some type of reading provision.Perhaps the greatest utility for EPROM's among experimenters is in the microcomputer field. For example, there is a host of different monitors avail-able for every microprocessor chip. Al-42though the monitors share some com-mon instructions, some have more (orbetter) features than others. Without amonitor, of course, the basic computercan't "do something" when it's turnedon.One could load monitor data from acassette tape machine, naturally, butthis is a cumbersome method. It's bestfor convenience and speed to have amonitor program in ROM (read-onlymemory) so that it's all there when youturn the computer on, and data will notbe lost if there's a momentary loss of linepower or when computer is turned off.Some computers have built-in ROMmonitors; many do not have monitors,so the computer owner must either buyPOPULAR ELECTRONICSa ROM monitor, have a supplier prepare ROM's or program his own.The latter route, using EPROM's could be the least expensive in the long run if a person continually upgrades his system whenever a better program or monitor comes along. An EPROM can be erased and reprogrammed very easi-ly. The device's bit pattern can be erased (all set to "zero") by exposing the chip's transparent quartz window to ultraviolet light. In essence, the UV light's photons displace electrons that were induced in the silicon gate to form the equivalent of "1's" in the bit pattern. Then, using the EPROM Programmer, F E B R U A R Y 1978the memory can be electronically repro-grammed. Once programmed, it willmaintain data when power is removed,but unlike a fuse-link ROM, it can losedata if exposed to strong UV light.The EPROM Programmer describedhere—which costs about 1/3 to 1/4 of com-mercial models—complements the ap-pealing economic picture of the popular1702A. The device's original tag wasabout $100, where today its cost rangesfrom $3 to $12, depending on quantitypurchased and source. In addition, sincecommercial houses charge as much as$40 to program an EPROM, doing it your-self can represent a substantial saving.Circuit Operation.The 1702AEPROM itself is fully static, easily inter-faced, requires no clocks, and is input/output TTL compatible. The three-stateoutput buffers are rated for one full TTLload. However, it does require a -9-voltsupply in addition to the conventional 5-volt operating supply.The Programmer can be built as astand-alone device using switches foraddress and data selection, or as a TTL-compatible peripheral for use with eitherswitches or microprocessor ports. Thecircuit shown in Fig. 1 provides all thetiming necessary for the Programmer.The 33.3-kHz clock, generated by IC1,43is routed to 8-bit shift register IC7 and to a synchronous counter chain consisting of IC2through IC6.Integrated circuits IC4, IC5and IC6,in conjunction with IC8D,form a divide-by-430 counter whose carry output enables a divide-by-32 counter formed by IC2and IC3. Capacitor C5and resistor R12provide 44the power-up initialization for the chain.Circuit action begins with the pro-gramming command (PROG), a nega-tive-going pulse used to asynchronouslyclear IC2and IC3.The pulse widthshould be limited to less than five mil-liseconds. The Qb output of IC2(pin 13)is inverted by IC8C to control the opera-tion of the divide-by-430 counter. Theoutput of this divider is taken from pin 11of IC4and is a 77.52-Hz (33.3 kHz/430)signal having a 20% duty cycle with 2.58ms on and 10.32 ms off. This waveformmeets the V DD/V GG Programmingduty cycle restrictions of the 1702AEPROM. Also, the 2.58-ms pulse fallsPOPULAR ELECTRONICSunder the 3-ms maximum specified for the 1702A programming pulse.This signal is applied to the serial in-put of IC7 and causes its eight outputs to sequence high in 30-us intervals, the pe-riod of the clock. Output B of IC7 begins the programming cycle by turning on the +47-volt supply through Q2 of the pow-er supply. This action sets the address and data lines to their proper levels. The address is complemented at this time. Thirty microseconds later, V DD and V GG move to their negative levels con-trolled by output C of IC4 driving transis-tors Q7and Q8.Output D (T/C or true/ complement) of IC7 follows on the next clock pulse and inverts the address lines to their true state. Outputs E, F, and G of IC7are not used. When output H goes high, it is AND'ed with output A by IC8A.This output is inverted by IC8B to drive Q6and provide the program pulse to SO1 (Fig. 2 or 3).These conditions are stable until the termination of the 2.58-ms pulse. At this point, output A of IC7goes low, thus ending the program pulse. Then output B disables the +47-volt supply. The shift register (IC7 )is completely cleared in six more clock pulses.During the last 30 microseconds of the 2.58-ms pulse, a carry is generated by IC4,causing the divide-by-32 counter (IC2, IC3 )to advance. This sequence repeats until the end of the 32nd itera-tion, when pin 13 of IC2goes true and shuts down the counter through IC8C. The total elapsed time for programming one 8-bit word is therefore about 413 ms. This period can be monitored by the optional status indicator (formed by Q10, R18 ,R19 and LED1) shown in Fig. 1.S w i t c h O p t i o n.Address and data se-lection during programming are provid-ed by the 16 spdt switches shown in Fig.2. A logic 0 on the address lines is accomplished by switching the line to the collector of ing the V c c as a reference, this will result in a level of -47 volts during the program pulse when the address true/complement (T/C) signal from IC7is high, thus se-lecting the true address. Placing the ad-dress switch in the 1 position ties that line to the complement of the signal present at the collector of Q12, resulting in a logic 1.For data input, connecting an output line to ground through the data switch results in a 47-volt level during the pro-gram cycle. This programs a logic 1 on the selected address output. Connection to the V c c line will leave the bit un-F E B R U A R Y 1978changed—a logic 0 during read.The small insert schematic in Fig. 2 isused to manually generate the program-HOW AN EPROM WORKSThe 1702A belongs to a family of electri-cally programmable, ultraviolet-light-era-sable, read-only memories. Each memorycell in the ROM has the appearance of aflip-flop with a new element—a "floatinggate," that is isolated from the silicon sub-strate by a narrow band of silicon dioxide(glass). This element is not connected toanything electrically. The output signalfrom each flip-flop, a 1 or a 0, depends onthe charge (or lack of it) on the gate.The application of a train of electricalpulses to a cell "charges" the floating gate,and causes the associated flip-flop to pro-duce a 1 at its output. This charge on thefloating gate leaks off after many ten's ofyears. Since there is no electrical connec-tion between the floating gate and the re-mainder of the ROM internal circuit, thecharge is not affected by the removal of thechip's operating power.The upper surface of the chip has aquartz window that is transparent to ultravi-olet (UV) light. If strong UV light is allowedto pass through the window, it will displacethe electrons from their shallow energy lev-els on the floating gate and cause them tomigrate to the silicon substrate where theircharge is neutralized. Typically, it takesseveral minutes of strong UV exposure toerase a device, and conventional roomlighting will not do the job—though expo-sure to direct sunshine may. After the UVexposure, all the cells go to a 0 output.ming command through pushbuttonswitch S18.T T L I n p u t O p t i o n.The circuit shownin Fig. 3 is similar to the switch optioncircuit shown in Fig. 2, except that theswitches are replaced by 16 transistorsand 8 exclusive-OR gates. Program-ming voltage levels are the same asthose described in the switch option.The transistors provide logic inversionas well as high-voltage isolation so thatconventional TTL logic levels can defineaddress and data selection.The gates in IC9and IC10are turnedon by the T/C signal to invert the ad-dress at the proper time. Resistors R48through R66provide leakage-currentpaths and insure good dynamic re-sponse.The address lines present one "LS"-load to the driving circuit and should beno problem to interface to a microcom-puter. The data lines must be driven bycircuits capable of sourcing at least 1mA at 1.7 V. Standard TTL devices willhandle this, as well as many of the LSII/O chips designed for microprocessors.Switches, connecting the inputs to the+ 5-volt line or ground, may be used.1702A D a t a.The read connections forthe 1702A (and family) are shown in Fig.4. The EPROM may be erased by expo-sure to high-intensity short-wave ultravi-olet radiation of 2537 angstroms. Therecommended integrated dosage is 6W-sec/cm2. Depending on the ultravioletlight source, the erasure may take from10 to 20 minutes. ONote: Part 2 of this article, nextmonth, will describe the power supply, pcboard, and construction.45P A R T 2Power supply, construction and checkout.Power Supply.The supply (Fig. 5)D5, R6, R7,and R8regulate the +75-delivers approximately +75 volts to a volt output down to +47 volts.

Resistor R9 insures a minimum sistors Q4and Q5,in conjunction with load on the regulator and provides a path for the D6 zener current. Capacitor C2and resistor R20prevent the high-gain circuit of Q5 from oscillating. Construction. Although the Program-mer can be built using any desired con-struction technique, a printed circuit board such as that shown in Fig. 6 is suggested. Observe the correct polari-ties when installing capacitors, diodes, transistors and IC's (using sockets, if de-56sired). Do not install transistors Q8andQ14through Q29 until after reading thecheckout section of this article. Mount 1-inch by 1/2-inch thin metal heat sinks ontransistors Q3and Q4 .Using the fuseas a guide, install a fuseholder or fuseclips at the F1position. Do not install asocket at position S02or the LED forLED1if you are going to mount theboard in an enclosure.The component installation shown inFig. 6 uses the TTL option so that thePOPULAR ELECTRONICSProgrammer can be used with a com-puter at some later date.Select a suitable enclosure whose front panel can support the eight ad-dress and write data switches in two rows (see photo). Also on the front panel M A R C H 1978are the on/off switch, the program push-button switch,LED1,and a zero-inser-tion-force 24-pin PROM socket. Identifythe switches and controls properly.Use a length of heavy bare wire to in-terconnect all of the upper lugs of the toprow of address switches. Interconnectthe bottom row of address switch lugssimilarly. Use the same technique on thedata switches. Using insulated wire,connect the upper lugs of the addressswitches to the upper lugs of the data57switches. Do the same with the lowerlugs—lower lugs to lower lugs.Using the small insert schematic ofthe S18 circuit shown in Fig. 2, connectthe normally closed contact of thisswitch to the top bare wire (gnd) of theaddress or data switches. Connect thetwo resistors and capacitor to the switchas shown, using the bottom lugs ofeither the address or data switches forthe 5-volt connection.Mount transformer T1 on one side ofthe chassis bottom plate. The rectifier,filter capacitor, and 5-volt regulator forthis supply can also be mounted on thebottom plate of the chassis. The pcboard will be mounted on spacers sothat it will not contact the componentsmounted within the chassis. Using thefour large corner holes in the pc boardas a guide, and with the edge connectortoward the front panel, mark and drill thefour spacer mounting holes.With the pc board held in its finalmounting position (edge connector fac-ing the front panel), cut lengths of in-sulated wire long enough to fit easily be-tween the S02 board position and the 24-pin front-panel socket. Do the same for the program switch and LED1 . Make similar connections from the edge con-nector to the center lug of each of the address and data switches. A pair of wires will also be needed from the edge-connector 5-volt pad to the bottom lugs of the switches. You will also need in-sulated leads from the two ac-pads and the 5-volt ground pads (on the pc board edge opposite the connector) to inter-connect to the power supply circuits.Drill a hole in the rear apron of the chassis and put a grommet in it for the ac line cord. Make sure all ac connec-tions are well insulated.After all the wiring is installed, the board can be mounted on spacers. Do not tighten the mounting hardware, how-ever, because the missing transistors will have to be installed after performing the following Checkout procedure.Checkout. Be sure transistors Q8 and Q14 through Q29 and the +47-volt line connection are not installed until after the regulator checkout is complete.After double checking the wiring (and pc board), adjust potentiometer R7 to its maximum series resistance, then tem-porarily jumper the collector of Q2 (Fig.5) to ground to enable the regulator. Ap-ply ac power to the high-voltage and 5-volt power supplies and check for the presence of +75-volt dc across filter ca-pacitor C1. If necessary, reverse the secondary ing a dc voltmeter of known accura-cy, monitor the voltage across R9 (Fig.5) and adjust R7 to obtain +47 ±1 volts.Leave the voltmeter connected across the 47-volt line.The current limiter is checked by mo-mentarily shunting R9 with a 68-ohm, 2-watt resistor. The voltage should drop to approximately 25 volts. If not, check Q1 ,Q3 and R1.Remove the temporary jumper from the collector of Q2 and note that the out-put voltage drops to zero. If not, Q2 is faulty or is being prematurely enabled by IC7 . Between programming cycles, IC7should be completely ing pushbutton switch S1B (Fig. 2),apply a pulse to the program command line and verify that the +47 volts occurs for about half a second. If it does, it is a good indication that the counters and clock are functioning normally.The 47-volt line and the transistors can now be installed.If you do not have a zero insertion-force socket, before installing the first PROM, loosen up the holes in the PROM socket using the leads of a 1/4-watt resistor. This should be done since the pins of many 1702A PROM's are fragile and may be bent trying to force them into a tight socket.With power applied, insert an erased EPROM in the socket, set the address and data switches in accordance with the first location of your truth table, and apply the programming command (S18).That location will be programmed within half a second. The optional LED pro-gramming indicator may be used to watch this timing.You now have 255 more locations to go. If you use the microprocessor option (Fig. 3) and a suitable program, the EPROM can be programmed in just a few minutes. O The 5-volt supply is mounted under the pc board. With a little care, as shown here, a very professional look can be attained.POPULAR ELECTRONICS 58。

C U S TO M E R C A S E S T UD Yeasy: solutions Gains Competitive Advantage in Managed Security ServicesSentinelOne Protects MSP and Its Customers While ReducingCosts and ComplexityThe Challenge: Protecting AgainstAdvanced ThreatsBased in Oslo, easy: solutions is a ManagedSecurity Provider (MSP) serving small andmedium-sized Norwegian companies that spana range of industries. True to its name, thecompany is dedicated to providing customizedIT solutions that are simple and friendly forusers while delivering leading-edge capabilitiesand security.As zero-day threats and ransomware attacks increased,easy: solutions’ customers began to see more frequent infections.The company’s SolarWinds security solutions and BitDefender weren’table to stop advanced malware and ransomware. Customers hadto send infected machines to easy: solutions in Oslo for remediation,which disrupted end-user productivity. Machine cleanup took criticaltime away from customer support, company management, andservice development.“We needed a better way to secure our network and our customers’networks,” said Niclas Lindblad, Chief Technical Officer at easy:solutions. “It had to be significantly more effective than what we had,and it also needed to enable management of multiple customers’networks from a single pane of glass.”The easy: solutions team began looking for a solution that included prevention, detection, and response capabilities without burdening endpoint CPUs. The solution also had to be easy for the team to manage and deploy. easy: solutions evaluated Carbon Black, Cylance, and Panda, but none met all of easy: solutions’ requirements. Lindblad and his team then turned to the Internet to seek other options, and they discovered SentinelOne.A Full Security Suiteeasy: solutions was immediately impressed by SentinelOne’s comprehensive protection and flexibility. It unifies prevention, detection, and response in one platform that’s powered by machine learning and intelligent automation. With SentinelOne, easy: solutions can predict malicious behavior across all vectors; rapidly eliminate threats with fully-automated, integrated response capabilities; and adapt defenses for its customers against evolving cyber attacks.“SentinelOne fit our environment much better than other solutions we tried,” said Lindblad. “We first tried it on our network and after just a few days, we knew it was the right solution for us and our customers. It gives us a full security suite for all of our servers, our client devices, and our customers’ devices.”Invisible Continuous Monitoring and AdaptationThe SentinelOne agent on each endpoint continuously monitors activity in the system core, as well as in files, processes, memory, registers, and network connections. Real-time analysis predicts harmful behavior and automatically eliminates threats, freeing the team from manual intervention processes. SentinelOne’s cloud intelligence blocks known threats, and when a new threat is detected, it immediately alerts and blocks all devices on the network so that the threat cannot spread. During response, SentinelOne can roll back all manipulated files to the pre-attack situation.“Our customers don’t even know that SentinelOne is there,” said Lindblad. “The agent runs in the background and users don’t have to do anything. SentinelOne works like an integrated part of our systems withoutburdening more than 1-2% of the CPU.”Stopping Infections and Reducing CostsSince SentinelOne was deployed, malware infections have stopped. All systems have been protected from Petya, WannaCry, and new ransomware variants, and Lindblad says that they have not had any computers sent in for remediation.Proactive Protection and ControlDuring an attack, SentinelOne visually maps the initial vector and how the threat progresses to other systems. Recently, one customer was attacked by ransomware. SentinelOne alerted the team, displayed the threat, and stopped the attack before it could infe ct the user’s system.“We contacted the customer and notified them that they were attacked, but not to worry, we stopped it before it could do damage,” said Lindblad. “Our ability to respond proactively with SentinelOne buildscustomer confidence and trust in our capabilities.”For more information about SentinelOne Endpoint ProtectionPlatform and the future of endpoint protection, please visit: . Powering Service InnovationSentinelOne’s flexibility enables easy: solutions to quickly adapt to changing customer requirements. With insight into computer processes and users’ patterns, easy: solutions can create new services around SentinelOne’s powerful platform.“Flexibility is as important as protection,” said Lindblad. “We’re eagerly anticipating upcoming SentinelOne capabilities that will enable us to strengthen our offering. We can create new services that protect customers’ sensitive data, intellectual property, and other assets and offer them at a reasonable price.”A Distinct AdvantageLindblad reports that easy: solutions customers who work with governmental agencies and other security-conscious organizations now have an advantage. SentinelOne meets the strictest security requirements, so easy: solutions customers receive fast approval on projects or engagements.“SentinelOne allowed us to easily increase protection across our multi-customer environment,” said Lindblad. “Other MSPs need multiple systems and software to achieve the same level of security that we enjoy with a single platform, which increases costs and complicates deployment, management, and support for them. SentinelOne is our advantage.”。
