outputs. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Applications Information
Capacitor Selection The capacitor type used for C1–C4 is not critical for
proper operation. The MAX202E, MAX206–MAX208E,
MAX211E, and MAX213E require 0.1µF capacitors,
and the MAX232E and MAX241E require 1µF capaci-
tors, although in all cases capacitors up to 10µF can
be used without harm. Ceramic, aluminum-electrolytic,
or tantalum capacitors are suggested for the 1µF
capacitors, and ceramic dielectrics are suggested for
the 0.1µF capacitors. When using the minimum recom-
mended capacitor values, make sure the capacitance
value does not degrade excessively as the operating
temperature varies. If in doubt, use capacitors with a
larger (e.g., 2x) nominal value. The capacitors’ effec-
tive series resistance (ESR), which usually rises at low
temperatures, influences the amount of ripple on V+
and V-.
Use larger capacitors (up to 10µF) to reduce the output
impedance at V+ and V-. This can be useful when
“stealing” power from V+ or from V-. The MAX203E and
MAX205E have internal charge-pump capacitors.
Bypass V CC to ground with at least 0.1µF. In applica-
tions sensitive to power-supply noise generated by the charge pumps, decouple V CC to ground with a capaci-tor the same size as (or larger than) the charge-pump capacitors (C1–C4).V+ and V- as Power Supplies A small amount of power can be drawn from V+ and V-,although this will reduce both driver output swing and noise margins. Increasing the value of the charge-pump capacitors (up to 10µF ) helps maintain performance when power is drawn from V+ or V-.Driving Multiple Receivers Each transmitter is designed to drive a single receiver.Transmitters can be paralleled to drive multiple receivers.Driver Outputs when Exiting Shutdown The driver outputs display no ringing or undesirable transients as they come out of shutdown.High Data Rates These transceivers maintain the RS-232 ±5.0V mini-mum driver output voltages at data rates of over 120kbps. F or data rates above 120kbps, refer to the Transmitter Output Voltage vs. Load Capacitance graphs in the Typical Operating Characteristics .Communication at these high rates is easier if the capacitive loads on the transmitters are small; i.e.,
short cables are best.

Each device con-tains one driver and one receiver. The MAX3483E and MAX3488E feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly termi-nated cables, allowing error-free data transmission at data rates up to 250kbps. The partially slew-rate-limited MAX3486E transmits up to 2.5Mbps. The MAX3485E, MAX3490E, and MAX3491E transmit at up to 12Mbps.All devices feature enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guar-antees a logic-high output if both inputs are open circuit.The MAX3488E, MAX3490E, and MAX3491E feature full-duplex communication, while the MAX3483E, MAX3485E, and MAX3486E are designed for half-duplex communication.Applications ●Telecommunications ●Industrial-Control Local Area Networks ●Transceivers for EMI-Sensitive Applications ●Integrated Services Digital Networks ●Packet Switching Features ●ESD Protection for RS-485 I/O Pins •±15kV—Human Body Model •±8kV—IEC 1000-4-2, Contact Discharge •±15kV—IEC 1000-4-2, Air-Gap Discharge ●Operate from a Single +3.3V Supply—No Charge Pump Required ●Interoperable with +5V Logic ●Guaranteed 12Mbps Data Rate (MAX3485E/MAX3490E/MAX3491E)●Slew-Rate Limited for Errorless Data Transmission (MAX3483E/MAX3488E)●2nA Low-Current Shutdown Mode (MAX3483E/MAX3485E/MAX3486E/MAX3491E)●-7V to +12V Common-Mode Input Voltage Range ●Full-Duplex and Half-Duplex Versions Available ●Industry-Standard 75176 Pinout (MAX3483E/MAX3485E/MAX3486E)●Current-Limiting and Thermal Shutdown for Driver Overload Protection Ordering Information continued at end of data sheet.PARTTEMP .

All rights reserved.Products and specifications discussed herein are subject to change by Micron without notice.The main memory array is divided into uniform blocks that can be erased independent-ly so that valid data can be preserved while old data is purged. PROGRAM and ERASE commands are written to the command interface of the memory. An on-chip program/erase controller simplifies the process of programming or erasing the memory by taking care of all special operations required to update the memory contents. The end of a PROGRAM or ERASE operation can be detected and any error condition can be identi-fied. The command set required to control the device is consistent with JEDEC stand-ards.CE#, OE#, and WE# control the bus operation of the device and enable a simple con-nection to most microprocessors, often without additional logic.The M29W supports asynchronous random read and page read from all blocks of the array. It features a write to buffer program capability that improves throughput by pro-gramming a buffer of 32 words in one command sequence. Also, in x16 mode, the en-hanced buffered program capability improves throughput by programming 256 words in one command sequence. The device V PP /WP# signal enables faster programming.The device contains a 128-word (x16) and 256-byte (x8) extended memory block. The user can program this additional space and then protect it to permanently secure the contents. The device also features different levels of hardware and software protection to secure blocks from unwanted modification.Figure 1: 128 Logic DiagramVV A[22:0]V /WP#DQ[14:0]SS 128Mb 3V Embedded Parallel NOR Flash General DescriptionCCMTD-1725822587-2335m29w_128mb.pdf - Rev.
