Description

The FM24V01 is a 128Kbit 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.

The FM24V01 performs write operations at bus

speed. No write delays are incurred. The next bus

cycle may commence immediately without the need

for data polling. In addition, the product offers write

endurance

orders

of

magnitude

higher

than

EEPROM. Also, F-RAM exhibits much lower power

during writes than EEPROM since write operations

do not require an internally elevated power supply

voltage for write circuits.

These capabilities make the FM24V01 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 FM24V01 provides substantial benefits to users

of serial EEPROM, yet these benefits are available in

a hardware drop-in replacement. The device is

available in an industry standard 8-pin SOIC package

using a familiar two-wire (I

incorporates a read-only Device ID that allows the

host to determine the manufacturer, product density,

and product revision. The device is guaranteed over

an industrial temperature range of -40°C to +85°C.
