FM93C46

1024-Bit Serial CMOS EEPROM

(MICROWIRE™ Synchronous Bus)

General Description

Features

FM93C46 is a 1024-bit CMOS non-volatile EEPROM organized

as 64 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.

Thereare7instructionsimplementedontheFM93C46forvarious

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.

I Wide V_CC2.7V - 5.5V

I Typical active current of 200µA

10µA standby current typical

1µA standby current typical (L)

0.1µA standby current typical (LZ)

I No Erase instruction required before Write instruction

I Self timed write cycle

I Device status during programming cycles

I 40 year data retention

“LZ” and “L” versions of FM93C46 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.

I Endurance: 1,000,000 data changes

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