The device is manufactured using Atmel’s high density nonvolatile memory technology and is compatible with the industry standard MCS-51™ instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C4051 is a pow-erful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.The AT89C4051 provides the following standard features: 4K Bytes of Flash, 128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and clock circuitry. In addition, the AT89C4051 is designed with static logic for opera-tion down to zero frequency and supports two software-selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power Down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the nexthardware reset.Block DiagramAT89C4051Pin DescriptionV CCSupply voltage.GNDGround.Port 1Port 1 is an 8-bit bidirectional I/O port. Port pins P1.2 to P1.7 provide internal pullups. P1.0 and P1.1 require exter-nal pullups. P1.0 and P1.1 also serve as the positive input (AIN0) and the negative input (AIN1), respectively, of the on-chip precision analog comparator. The Port 1 output buffers can sink 20 mA and can drive LED displays directly. When 1s are written to Port 1 pins, they can be used as inputs. When pins P1.2 to P1.7 are used as inputs and are externally pulled low, they will source current (I IL) because of the internal pullups.Port 1 also receives code data during Flash programming and verification.Port 3Port 3 pins P3.0 to P3.5, P3.7 are seven bidirectional I/O pins with internal pullups. P3.6 is hard-wired as an input to the output of the on-chip comparator and is not accessible as a general purpose I/O pin. The Port 3 output buffers can sink 20 mA. When 1s are written to Port 3 pins they are pulled high by the internal pullups and can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current (I IL) because of the pullups. Port 3 also serves the functions of various special features of the AT89C4051 as listed below:Port 3 also receives some control signals for Flash pro-gramming and verification.RSTReset input. All I/O pins are reset to 1s as soon as RST goes high. Holding the RST pin high for two machine cycles while the oscillator is running resets the device.Each machine cycle takes 12 oscillator or clock cycles. XTAL1Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2Output from the inverting oscillator amplifier.Oscillator CharacteristicsXTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 1. Either a quartz crystal or ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 2. There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide-by-two flip-flop, but minimum and maxi-mum voltage high and low time specifications must be observed.Figure 1.

Note that not all of the addresses are occupied, and unoc-cupied addresses may not be implemented on the chip. Read accesses to these addresses will in general return random data, and write accesses will have an indetermi-nate er software should not write 1s to these unlisted loca-tions, since they may be used in future products to invoke new features. In that case, the reset or inactive values of the new bits will always be 0.Table 1.

It contains 4K bytes of flash program memory. It is fully compatible with the MCS-51 architecture, and can be programmed using the MCS-51 instruction set. However, there are a few considerations one must keep in mind when utilizing certain instructions to program this device.All the instructions related to jumping or branching should be restricted such that the destination address falls within the physical program memory space of the device, which is 4K for the AT89C4051. This should be the responsibility of the software programmer. For example, LJMP 0FE0H would be a valid instruction for the AT89C4051 (with 4K of memory), whereas LJMP 1000H would not.1. Branching instructions:LCALL, LJMP, ACALL, AJMP, SJMP, JMP @A+DPTR These unconditional branching instructions will execute correctly as long as the programmer keeps in mind that the destination branching address must fall within the physical boundaries of the program memory size (locations 00H to FFFH for the 89C4051). Violating the physical space limits may cause unknown program behavior.CJNE [...], DJNZ [...], JB, JNB, JC, JNC, JBC, JZ, JNZ With these conditional branching instructions the same rule above applies. Again, violating the memory boundaries may cause erratic execution.For applications involving interrupts the normal interrupt service routine address locations of the 80C51 family archi-tecture have been preserved.2. MOVX-related instructions, Data Memory:The AT89C4051 contains 128 bytes of internal data mem-ory. Thus, in the AT89C4051 the stack depth is limited to 128 bytes, the amount of available RAM. External DATA memory access is not supported in this device, nor is exter-nal PROGRAM memory execution. Therefore, no MOVX [...] instructions should be included in the program.A typical 80C51 assembler will still assemble instructions, even if they are written in violation of the restrictions men-tioned above. It is the responsibility of the controller user to know the physical features and limitations of the device being used and adjust the instructions used correspond-ingly.Program Memory Lock BitsOn the chip are two lock bits which can be left unpro-grammed (U) or can be programmed (P) to obtain the addi-tional features listed in the table below:Lock Bit Protection Modes(1)Note: 1.The Lock Bits can only be erased with the Chip Erase operation.Idle ModeIn idle mode, the CPU puts itself to sleep while all the on-chip peripherals remain active. The mode is invoked by software. The content of the on-chip RAM and all the spe-cial functions registers remain unchanged during this mode. The idle mode can be terminated by any enabled interrupt or by a hardware reset.P1.0 and P1.1 should be set to ’0’ if no external pullups are used, or set to ’1’ if external pullups are used.It should be noted that when idle is terminated by a hard-ware reset, the device normally resumes program execu-tion, from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-chip hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited. To eliminate the possibility of an unexpected write to a port pin when Idle is terminated by reset, the instruction following the one that invokes Idle should not be one that writes to a port pin or to external memory.Power Down ModeIn the power down mode the oscillator is stopped, and the instruction that invokes power down is the last instruction executed. The on-chip RAM and Special Function Regis-ters retain their values until the power down mode is termi-nated. The only exit from power down is a hardware reset. Reset redefines the SFRs but does not change the on-chip RAM. The reset should not be activated before V CC is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and sta-bilize.P1.0 and P1.1 should be set to ’0’ if no external pullups are used, or set to ’1’ if external pullups are used.Program Lock BitsLB1LB2Protection Type1U U No program lock features.2P U Further programming of the Flashis disabled.3P P Same as mode 2, also verify isdisabled.Brown-Out DetectionWhen V CC drops below the detection threshold, all port pins (except P1.0 and P1.1) are weakly pulled high. When V CC goes back up again, an internal Reset is automatically generated after a delay of typically 15 msec. The nominal brown-out detection threshold is 2.3V ± 10%.Programming The FlashThe AT89C4051 is shipped with the 4K bytes of on-chip PEROM code memory array in the erased state (i.e., con-tents = FFH) and ready to be programmed. The code mem-ory array is programmed one byte at a time. Once the array is programmed, to re-program any non-blank byte, the entire memory array needs to be erased electrically. Internal Address Counter: The AT89C4051 contains an internal PEROM address counter which is always reset to 000H on the rising edge of RST and is advanced by apply-ing a positive going pulse to pin XTAL1.Programming Algorithm: To program the AT89C4051, the following sequence is recommended.1.Power-up sequence:Apply power between V CC and GND pinsSet RST and XTAL1 to GND2.Set pin RST to ’H’Set pin P3.2 to ’H’3.Apply the appropriate combination of ’H’ or ’L’ logiclevels to pins P3.3, P3.4, P3.5, P3.7 to select one of the programming operations shown in the PEROM Pro-gramming Modes table.To Program and Verify the Array:4.Apply data for Code byte at location 000H to P1.0 toP1.7.5.Raise RST to 12V to enable programming.6.Pulse P3.2 once to program a byte in the PEROM arrayor the lock bits. The byte-write cycle is self-timed and typically takes 1.2 ms.7.To verify the programmed data, lower RST from 12V tologic ’H’ level and set pins P3.3 to P3.7 to the appropriate levels. Output data can be read at the port P1 pins.8.To program a byte at the next address location, pulseXTAL1 pin once to advance the internal address counter.Apply new data to the port P1 pins.9.Repeat steps 5 through 8, changing data and advancingthe address counter for the entire 4K bytes array or until the end of the object file is reached.10.Power-off sequence:set XTAL1 to ’L’set RST to ’L’Turn V CC power offData Polling: The AT89C4051 features Data Polling to indicate the end of a write cycle. During a write cycle, an attempted read of the last byte written will result in the com-plement of the written data on P1.7. Once the write cycle has been completed, true data is valid on all outputs, and the next cycle may begin. Data Polling may begin any time after a write cycle has been initiated.Ready/Busy: The Progress of byte programming can also be monitored by the RDY/BSY output signal. Pin P3.1 is pulled low after P3.2 goes High during programming to indi-cate BUSY. P3.1 is pulled High again when programming is done to indicate READY.Program Verify: If lock bits LB1 and LB2 have not been programmed code data can be read back via the data lines for verification:1.Reset the internal address counter to 000H by bringingRST from ’L’ to ’H’.2.Apply the appropriate control signals for Read Code dataand read the output data at the port P1 pins.3.Pulse pin XTAL1 once to advance the internal addresscounter.4.Read the next code data byte at the port P1 pins.5.Repeat steps 3 and 4 until the entire array is read.The lock bits cannot be verified directly. Verification of the lock bits is achieved by observing that their features are enabled.Chip Erase: The entire PEROM array (4K bytes) and the two Lock Bits are erased electrically by using the proper combination of control signals and by holding P3.2 low for 10 ms. The code array is written with all “1”s in the Chip Erase operation and must be executed before any non-blank memory byte can be re-programmed.AT89C4051Reading the Signature Bytes: The signature bytes are read by the same procedure as a normal verification of locations 000H, 001H, and 002H, except that P3.5 and P3.7 must be pulled to a logic low. The values returned are as follows.(000H) = 1EH indicates manufactured by Atmel (001H) = 41H indicates 89C4051Programming InterfaceEvery code byte in the Flash array can be written and the entire array can be erased by using the appropriate combi-nation of control signals. The write operation cycle is self-timed and once initiated, will automatically time itself to completion.All major programming vendors offer worldwide support for the Atmel microcontroller series. Please contact your local programming vendor for the appropriate software revision.Flash Programming ModesNotes:1.The internal PEROM address counter is reset to 000H on the rising edge of RST and is advanced by a positive pulse atXT AL 1 pin.2.Chip Erase requires a 10-ms PROG pulse.3.P3.1 is pulled Low during programming to indicate RDY/BSY .ModeRST/VPP P3.2/PROGP3.3P3.4P3.5P3.7Write Code Data (1)(3)12VLHHHRead Code Data (1)H H L L H H Write LockBit - 112VHHHHBit - 212V H H L LChip Erase 12VH L L LRead Signature Byte H H L L L L(2)Figure 3.

与8051兼容的单片机及其应用选型一、引言在世界上8位单片机诞生后不久，8051的出现了，由于8051在当时8位单片机中的突出性能，它成为事实上的工业标准。

由于Intel公司的技术开放和8051的经典体系结构、良好的兼容性，众多的半导体厂商都热衷于8051及其兼容单片机的发展，特别是近几年来，随着微电子技术与计算机技术的迅猛发展，8051及其兼容单片机的发展日新月异、品种繁多，令人目不暇接。

8051及其兼容单片机的生产厂商各施绝技，生产出各具特色的8051及其兼容单片机，概括说来，新型的8051及其兼容单片机有如下的特点或功能：1．高速度；2．混合(模拟与数字)信号处理；3．低功耗；4．多时钟和实时时钟；5．大容量存储器；6．大数量的I/O口和多功能、可配置I/O口；7．基于串口或JTAG结构的在系统调试；8．多种复位源；9．片内可编程门阵列和系统可配置；10．多种串口；11．DMA功能；12．USB接口；13．视频（电视）信号处理与控制；14．网络接口；……由于与8051兼容的单片机品种繁多，限于篇幅，要在本文中介绍所有新型的与8051兼容单片机是不可能的，而要重点介绍若干个品种，既有难以取舍的窘迫，又有挂一漏万之嫌。

即使是仅介绍这些新型的单片机的特点，恐怕也难在一篇短文中叙述清楚。

作者只好把所收集的与8051兼容的单片机及其特点整理成表格，供大家在开发选型时参考。

应该说明的是，该表格不可能把所有的与8051兼容的单片机都收入到，所列特点也仅仅是概括性的，不可能把所有的技术指标都给列出。

二、与8051兼容的单片机下表列出了与8051兼容的单片机的生产公司、信号及其特点与主要技术指标。

三、结束语本文用列表的形式给出了与8051兼容的单片机的生产公司、信号及其特点与主要技术指标。

这些品种繁多、性能优异而又各具特色的新型单片机，为同行们开发新产品和改造已有产品提供了契机与方便。

相信本文能为读者提供极高的参考价值。
