General Description
The FM25C041U is a 4K (4,096) 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 synchronously control data transfer between the
SPI microcontroller and the EEPROM. In addition, the serial
interface allows a minimal pin count, packaging designed to
simplify PC board layout requirements and offers the designer a
variety of low voltage and low power options.
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
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.
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.
Functions
I SPI MODE 1 interface
I 4,096 bits organized as 512 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
Features
I Sequential read of entire array
I 4 byte "Page write" mode to minimize total write time per
byte
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
I Typical 1A standby current (I
SB) for "L" devices and 0.1A
standby current for "LZ" devices.
I Endurance: Up to 1,000,000 data changes
I Data retention greater than 40 years
