MB91305
Overview
MB91305 is a single-chip microcontroller that has a 32-bit high-performance RISC CPU as well as built-in I/O resources for embedded controllers requiring high-performance and high-speed CPU processing. The FR family is the most suitable for embedded applications, for example, DVD player, printer, TV, and PDP control, that require a high level of CPU processing power.
