■DESCRIPTION
The MB91270 series is single chip microcontroller that builds various I/O resources and the bus control mechanisms into by using 32-bit efficient RISC CPU for the built-in control being demanded for CPU processing high performance/high-speed. RAM (for reading data) is included in order tosupport CPU to access to the vast address space and to speed up the execution of CPU instructions. This series is optimized to the embedded applications; automotive applications such as car audio or car air-conditioning equipment that require high-performance CPU processing power.
