NM93C56A 2K-Bit Serial CMOS EEPROM

(MICROWIRE

Synchronous Bus)

March 2000

NM93C56A

2K-Bit Serial CMOS EEPROM

(MICROWIRE™ Synchronous Bus)

General Description

NM93C56A is a 2048-bit CMOS non-volatile EEPROM organized

as 128 x 16-bit array. This device features MICROWIRE interface

which is a 4-wire serial bus with chipselect (CS), clock (SK), data

input (DI) and data output (DO) signals. This interface is compat-

ible to many of standard Microcontrollers and Microprocessors.

This device offers a pin (ORG), using which, the user can select

the format of the data (16-bit or 8-bit). If ORG is tied to GND, then

8-bit format is selected, while if ORG is tied to V

, then 16-bit

format is selected. There are 7 instructions implemented on the

NM93C56A for various Read, Write, Erase, and Write Enable/

Disable operations. This device is fabricated using Fairchild

Semiconductor floating-gate CMOS process for high reliability,

high endurance and low power consumption.

“LZ” and “L” versions of NM93C56A offer very low standby current

making them suitable for low power applications. This device is

offered in both SO and TSSOP packages for small space consid-

erations.

Features
