Description

Pin Configuration

The FM24CL04B is a 4-kilobit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or FRAM is

nonvolatile and performs reads and writes like a

RAM. It provides reliable data retention for 38 years

while eliminating the complexities, overhead, and

system level reliability problems caused by EEPROM

and other nonvolatile memories.

SDA

The FM24CL04B performs write operations at bus

speed. No write delays are incurred. Data is written to

the memory array in the cycle after it has been

successfully transferred to the device. The next bus

cycle may commence immediately without the need

for data polling. The FM24CL04B is capable of

supporting 10¹⁴read/write cycles, or a million times

more write cycles than EEPROM.

Write Protect

These capabilities make the FM24CL04B ideal for

nonvolatile memory applications requiring frequent

or rapid writes. Examples range from data collection

where the number of write cycles may be critical, to

demanding industrial controls where the long write

time of EEPROM can cause data loss. The

combination of features allows more frequent data

writing with less overhead for the system.

FM24CL04B-GTR “Green”/RoHS 8-pin SOIC,

Tape & Reel

The FM24CL04B provides substantial benefits to

users of serial EEPROM, yet these benefits are

available in a hardware drop-in replacement. The

FM24CL04B is available in an industry standard 8-

pin SOIC package and uses a familiar two-wire

protocol. The specifications are guaranteed over an

industrial temperature range of -40°C to +85°C.

This is a product that has fixed target specifications but are subject

to change pending characterization results.
