FM24C64S

The RIC FM24C64S is a 64-kilobit nonvolatile FRAM serial memory, organized as 8,192 x 8 bits. It utilizes an advanced ferroelectric process, providing RAM-like operation with nonvolatile data retention for up to 10 years at 85°C. This memory offers high endurance with 10 billion read/write cycles and features a NoDelay™ write capability, allowing write operations at bus speed without incurring delays.

The FM24C64S employs a fast two-wire serial interface with a maximum bus frequency of 1 MHz, supporting legacy timing for 100 kHz and 400 kHz. It operates on a true 5V supply, consuming 150 μA active current at 100 kHz and 10 μA standby current. The device is designed for industrial temperature ranges from -40°C to +85°C and is available in 8-pin SOP or DIP packages.

This FRAM memory serves as a direct hardware replacement for EEPROMs, eliminating complexities and system-level reliability issues associated with traditional nonvolatile memories. Its capabilities make it ideal for applications requiring frequent or rapid data writes, such as data collection systems and industrial controls where EEPROM write times can cause data loss.
