■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.
