MB85RS256A概要说明书

MB85RS256A is a 256K-bits FRAM LSI with serial interface (SPI), using the ferroelectric
process and CMOS process technologies for forming the nonvolatile memory cells.
Because FRAM is able to write high-speed even though a nonvolatile memory,
it is suitable for the log management and the storage of the resume data, etc.
