■ DESCRIPTION
The MB91610 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
