MB85RS256B/128B/64/64V/16/16N FeRAM Chips

RAMXEED MB85RS256B/128B/64/64V/16/16N Ferroelectric Random Access Memory (FeRAM) Chips support a wide range of capacities, from 16Kbit to 256Kbit. These chips are configured with 2,048 to 32,768 words x 8bits, using ferroelectric process and silicon-gate CMOS process technologies to form the nonvolatile memory cells. The FeRAM chips feature a Serial Peripheral Interface (SPI) and 1012 read/write cycle endurance. These chips can retain data without a backup battery, unlike SRAM. The FeRAM chips operate at 20MHz or 33MHz, with power supply voltages ranging from 2.7V to 3.6V and 3V to 5.5V. These chips are available in SOP-8 (150mil) and SON-8 (2mm x 3mm) packages.
