â OVERVIEW
MB91245/S series is Fujitsuâs general-purpose 32-bit RISC microcontroller, 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 with other products in the FR* family.
This series incorporates an LCD controller and stepping motor controller.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
