Fast Two-wire Serial Interface
Description
The FM24C04A is a 4-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.
Unlike serial EEPROMs, the FM24C04A 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.
These capabilities make the FM24C04A 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 reduced overhead for the system.
The FM24C04A provides substantial benefits to users
of serial EEPROM, yet these benefits are available in
a hardware drop-in replacement. The FM24C04A is
available in industry standard 8-pin packages using a
two-wire protocol. The specifications are guaranteed
over an industrial temperature range of -40°C to
+85°C.
This product conforms to specifications per the terms of the Ramtron
standard warranty. The product has completed Ramtron’s internal
qualification testing and has reached production status.
