Description

The FM24CL04 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 10 years

while eliminating the complexities, overhead, and

system level reliability problems caused by EEPROM

and other nonvolatile memories.

Unlike serial EEPROMs, the FM24CL04 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 FM24CL04 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.

The FM24CL04 provides substantial benefits to users

of serial EEPROM, yet these benefits are available in

a hardware drop-in replacement. The FM24CL04 is

available in an industry standard 8-pin package using

a two-wire protocol. The specifications are

guaranteed over an industrial temperature range of -

40擄C to +85擄C.
