24C64 Datasheet | Ramtron

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 - No Delay™ 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 k Hz & 400 k Hz 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 plexities, 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...
