■ 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.

■ FEATURES
