FR80 MB91625 Series
MB91F627/V650
■ DESCRIPTION
The MB91625 series is a line of FUJITSU MICROELECTRONICS microcontrollers based on a 32-bit RISC CPU
core that feature a variety of peripheral functions for embedded applications that demand high-performance and
high-speed CPU processing.
This series is based on the FR80* family CPU and is implemented as a single chip.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of Fujitsu Microelectronics Limited.
■ FEATURES
