The Ramtron FM1808-70-PG is a 256-kilobit nonvolatile memory utilizing an advanced ferroelectric process (FRAM). It provides data retention for 45 years without the complexities of battery-backed SRAM (BBSRAM).
Key features include a 70 ns access time and 130 ns cycle time, making it suitable for applications requiring frequent or rapid writes. The device operates with low power consumption, drawing 25 mA active current and 20 µA standby current. It is organized as 32,768 x 8 bits and offers high endurance with 10 billion read/write cycles.
Designed for industrial applications, the FM1808-70-PG operates within a temperature range of -40°C to +85°C. It is available in a 28-pin DIP package, facilitating design retrofits, and also in a 28-pin SOIC package for surface mounting.
This FRAM memory is SRAM and EEPROM compatible, adhering to the JEDEC 32Kx8 pinout, simplifying integration into existing designs. Its monolithic reliability and resistance to environmental factors like moisture and vibration make it a robust choice for nonvolatile memory needs.
