MB85RS64TU

MB85RS64TU is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 8,192 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.

MB85RS64TU adopts the Serial Peripheral Interface (SPI).

The MB85RS64TU is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS64TU can be used for 10¹³ read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E2PROM.

MB85RS64TU does not take long time to write data like Flash memories or E2PROM, and MB85RS64TU takes no wait time.

MB85RS64TU is suitable for application in extremely cold region, such as flow meter or sensor device and so forth, with extended operating temperature range.
