■DESCRIPTIONS

MB91210 series is Fujitsu’s general-purpose 32-bit RISCmicrocontroller, which is designed for embedded control

applications that require high-speed real-time processing of consumer appliances. This microcontroller uses

FR60Lite as its CPU, compatible withother products in the FR* family.

This series incorporates a built-in LIN-UART and CAN controller.

■FEATURES
