Overview

NM93C66 4096-Bit Serial CMOS EEPROM (MICROWIRETM Synchronous Bus) February 2000 NM93C66 4096-Bit Serial CMOS EEPROM (MICROWIRE™ Synchronous Bus) General Description NM93C66 is a 4096-bit CMOS non-volatile EEPROM organized as 256 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 compatible to many of standard Microcontrollers and Microprocessors.
There are 7 instructions implemented on the NM93C66 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 NM93C66 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 considerations.
