FM24C64

FM24C64 64Kb FRAM Serial Memory Features 64K bit Ferroelectric Nonvolatile RAM Organized as 8,192 x 8 bits High endurance 10 Billion (1010) read/writes 10 year data retention at 85° C NoDelay™ write Advanced high-reliability ferroelectric process Fast Two-wire Serial Interface Up to 1 MHz maximum bus frequency Direct hardware replacement for EEPROM Supports legacy timing for 100 kHz & 400 kHz Description The FM24C64 is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile but operates in other respects as 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 FM24C64 performs write operations at bus speed. No write delays are incurred. Data is written to the memory array mere hundreds of nanoseconds after it has been successfully tran...
