Description

Pin Configuration

The FM24C64 is a 64-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 45 years

while eliminating the complexities, overhead, and

system level reliability problems caused by

EEPROM and other nonvolatile memories.

The FM24C64 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. The FM24C64 is

capable of supporting 10¹²read/write cycles, or a

million times more write cycles than EEPROM.

Function

These capabilities make the FM24C64 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

writes with less overhead for the system.

The FM24C64 provides substantial benefits to users

of serial EEPROM, yet these benefits are available in

a hardware drop-in replacement. The FM24C64 is

available in an industry standard 8-pin SOIC package

using a two-wire protocol. The specifications are

guaranteed over an industrial temperature range of

-40°C to +85°C.
