DESCRIPTION
MB91461 is a line of the general-purpose 32-bit RISC microcontrollers designed for embedded control applica-
tions such as consumer devices and vehicle system, which require high-speed real-time processing. MB91461
uses the FR60 CPU compatible with the FR family* CPUs.
MB91461 contains the LIN-UART and CAN controller.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
