■DESCRIPTION
The MB91470/480 series is Fujitsu's general-purpose 32-bit RISC microcontroller, which is designed for
embedded control applications that require high-speed processing performance.
This series uses the FR60 CPU, which is compatible with the FR* family of CPUs.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
