Description

Pin Configuration

The FM25040B is a 4-kilobit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or F-RAM is

nonvolatile but operates in other respects as 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 FM25040B performs write operations at bus

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

the memory array immediately after it has been

successfully transferred to the device. The next bus

cycle may commence immediately without the need

for data polling. The FM25040B is capable of

supporting up to 10¹²read/write cycles, or a million

times more write cycles than EEPROM.

These capabilities make the FM25040B 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.

replacement. The FM25040B uses the high-speed

SPI bus, which enhances the high-speed write

capability of F-RAM technology. 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.
