FM93C66A

4K-Bit Serial CMOS EEPROM

(MICROWIRE™ Synchronous Bus)

General Description

Features

FM93C66A 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 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_CC, then 16-bit

format is selected. There are 7 instructions implemented on the

FM93C66A 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.

I Wide V_CC2.7V - 5.5V

I User selectable organization

x16 (ORG = 1)

x8 (ORG = 0)

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 FM93C66A 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
