Part#: FM25L16B-GTR
Part Category: Memory ICs

Manufacturer: Infineon Technologies AG

Description: FRAM, 2KX8, Serial, SPI, PDSO8

The FM25L16B is a 16-Kbit nonvolatile memory employing an
advanced ferroelectric process. A ferroelectric random access
memory or F-RAM is nonvolatile and performs reads and writes
similar to a RAM. It provides reliable data retention for 151 years
while eliminating the complexities, overhead, and system level
reliability problems caused by serial flash, EEPROM, and other
nonvolatile memories.
Unlike serial flash and EEPROM, the FM25L16B performs write
operations at bus speed. No write delays are incurred. Data is
written to the memory array immediately after each byte is
successfully transferred to the device. The next bus cycle can
commence without the need for data polling. In addition, the
product offers substantial write endurance compared with other
nonvolatile memories. The FM25L16B is capable of supporting
1014 read/write cycles, or 100 million times more write cycles
than EEPROM.
These capabilities make the FM25L16B 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 serial flash or EEPROM can cause data loss.
The FM25L16B provides substantial benefits to users of serial
EEPROM or flash as a hardware drop-in replacement. The
FM25L16B uses the high-speed SPI bus, which enhances the
high-speed write capability of F-RAM technology. The device
specifications are guaranteed over an industrial temperature
range of –40 C to +85 C.
