Description

Pin Configuration

The FM24C04A 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 45 years

while eliminating the complexities, overhead, and

system level reliability problems caused by EEPROM

and other nonvolatile memories.

Unlike serial EEPROMs, the FM24C04A 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.

These capabilities make the FM24C04A 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 reduced overhead for the system.

The FM24C04A provides substantial benefits to users

of serial EEPROM, yet these benefits are available in

a hardware drop-in replacement. The FM24C04A is

available in industry standard 8-pin packages using a

two-wire protocol. The specifications are guaranteed

over an industrial temperature range of -40°C to

+85°C.
