FM93C66A

4K-Bit Serial CMOS EEPROM

(MICROWIRE™ Bus Interface)

General Description

Features

The FM93C66A is 4096 bits of CMOS nonvolatile EEPROM

(Electrically Erasable Programmable Read Only Memory) with

MICROWIRE serial interface. FM93C66A can be configured for

either 256 x 16 bit or 512 x 8 bit array using an organization (ORG)

inputpin.ThisdeviceisfabricatedusingFairchildSemiconductor's

floating gate CMOS process for high reliability, high endurance

and low power consumption. This device is available in 8-pin DIP,

SO and TSSOP packages.

I 2.7V to 5.5V operation in all modes

I Typical active current of 200µA

10µA standby current typical

1µA standby current typical (L)

0.1µA standby current typical (LZ)

I Self-timed programming cycle

I Device status indication during programming mode

I No erase required before write

The MICROWIRE serial interface offered by this EEPROM en-

ables simple interface to a wide variety of microcontrollers and

microprocessors. There are 7 instructions that operate the

FM93C66A: Read, Erase/Write Enable, Erase, Write, Erase/

Write Disable, Write All and Erase All.

I Reliable CMOS floating gate technology

I MICROWIRE compatible serial I/O

I 40 years data retention

I Endurance: 1,000,000 data changes

I Packages available: 8-pin TSSOP, 8-pin SO, 8-pin DIP

I Schmitt Trigger inputs and V_CClockout to prevent data

corruption
