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 FM25L16 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 product offers virtually unlimited write endurance, orders of magnitude more endurance than EEPROM.
FRAM also exhibits much lower power during writes than EEPROM.
These capabilities make the FM25L16 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 FM25L16 provides substantial benefits to users of serial EEPROM as a hardware drop-in replacement.
The FM25L16 uses the high-speed SPI...
