Description

The FM25L512 is a 512-kilobit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or F-RAM 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 FM25L512 performs

write operations at bus speed. No write delays are

incurred. The next bus cycle may commence

immediately without the need for data polling. The

next bus cycle may start immediately. In addition, the

product offers virtually unlimited write endurance.

Also, F-RAM exhibits much lower power

consumption than EEPROM.

These capabilities make the FM25L512 ideal for

nonvolatile memory applications requiring frequent

or rapid writes or low power operation. 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 FM25L512 provides substantial benefits to users

of serial EEPROM as a hardware drop-in

replacement. The FM25L512 uses the high-speed SPI

bus, which enhances the high-speed write capability

of F-RAM technology. Device specifications are

guaranteed over an industrial temperature range of

-40°C to +85°C.
