Description

The FM25L16B is a 16-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 38 years

while eliminating the complexities, overhead, and

system level reliability problems caused by

EEPROM and other nonvolatile memories.

The FM25L16B performs write operations at bus

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

the memory array immediately after each byte has

been transferred to the device. The next bus cycle

may commence without the need for data polling.

The FM25L16B is capable of supporting 10

read/write cycles, or a million times more write

cycles than EEPROM.

These capabilities make the FM25L16B 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 FM25L16B provides substantial benefits to users

of serial EEPROM as a hardware drop-in

replacement. The FM25L16B uses the high-speed

SPI bus, which enhances the high-speed write

capability

F-RAM

technology.

Device

specifications are guaranteed over an industrial

temperature range of -40°C to +85°C.
