FM25C160U

16K-Bit SPI™ Interface

Serial CMOS EEPROM

General Description

Functions

The FM25C160U is a 16K bit serial interface CMOS EEPROM

(Electrically Erasable Programmable Read-Only Memory). This

device fully conforms to the SPI 4-wire protocol which uses Chip

Select (/CS), Clock (SCK), Data-in (SI) and Data-out (SO) pins to

synchronouslycontroldatatransferbetweentheSPImicrocontroller

andtheEEPROM.Inaddition,theserialinterfaceallowsaminimal

pin count, packaging designed to simplify PC board layout re-

quirementsandoffersthedesigneravarietyoflowvoltageandlow

power options.

I SPI MODE 0 interface

I 16K bits organized as 2048 x 8

I Extended 2.7V to 5.5V operating voltage

I 2.1 MHz operation @ 4.5V - 5.5V

I Self-timed programming cycle

I "Programming complete" indicated by STATUS REGISTER

polling

I /WP pin and BLOCK WRITE protection

This SPI EEPROM family is designed to work with the 68HC11 or

any other SPI-compatible, high-speed microcontroller and offers

both hardware (/WP pin) and software ("block write") data protec-

tion. For example, entering a 2-bit code into the STATUS REGIS-

TER prevents programming in a selected block of memory and all

Features

I Sequential read of entire array

I 16 byte "Page write" mode to minimize total write time per

byte

programming can be inhibited by connecting the /WP pin to V_SS

;

allowing the user to protect the entire array or a selected section.

In addition, SPI devices feature a /HOLD pin, which allows a

temporary interruption of the datastream into the EEPROM.

I /WP pin and BLOCK WRITE protection to prevent inadvert-

ent programming as well as programming ENABLE and

DISABLE opcodes.

I /HOLD pin to suspend data transfer

Fairchild EEPROMs are designed and tested for applications

requiring high endurance, high reliability, and low power con-

sumption for a continuously reliable non-volatile solution for all

markets.

I Typical 1µA standby current (I_SB) for "L" devices and 0.1µA

standby current for "LZ" devices.

I Endurance: Up to 1,000,000 data changes

I Data retention greater than 40 years
