FRAM SPI(for G.U)
MB85RS2MTY
产品概述
MB85RS2MTY adopts the Serial Peripheral Interface (SPI).
The MB85RS2MTY is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS2MTY 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.
As MB85RS2MTY does not need any waiting time in writing process, the write cycle time of MB85RS2MTY is much shorter than that of Flash memories or E2PROM.
