■ Objectives and Intended Reader
The MB91350A series is one of the FR60 family of microcontrollers. The FR60 family of microcontrollers
is based on the FR30/40 family of CPUs, which use a 32-bit high-performance RISC CPU as the core CPU.
The FR60 family offers enhanced bus access. The MB91350A series is a single-chip microcontroller with
built-in peripheral resources. The MB91350A series is ideal for embedded control applications that require
high-performance or high-speed CPU processing.
This manual is intended for engineers who will develop products using the MB91350A series and describes
the functions and operations of the MB91350A series. Read this manual thoroughly.
