PREFACE
■ Objectives and Intended Reader
Thank you for using Fujitsu semiconductor products.
The MB91301 series is a standard microcontroller that has a 32-bit high-performance RISC
CPU as well as built-in I/O resources and bus control mechanisms for embedded controller that
requires high-performance and high-speed CPU processing. Although the MB91301 series
basically uses external bus access to support a vast address space accessed by a 32-bit CPU,
it has a 4 Kbytes instruction cache memory and 4 Kbytes RAM (for data) to increase the speed
at which the CPU executes instructions.
The MB91301 series is most suitable for embedded applications, such as digital video cameras,
navigation systems, and DVD players, that require a high level of CPU processing power.
The MB91301 series is one of the FR60 of microcontrollers, which are based on the FR30/40 of
CPUs. It has enhanced bus access and is optimized for high-speed use.
This manual is intended for engineers who will develop products using the MB91301 series and
describes the functions and operations of the MB91301 series. Read this manual thoroughly.
For more information on instructions, see the "Instructions Manual".
