32-bit RISC Microcontroller
CMOS
FR30 MB91121 Series
MB91121
■ DESCRIPTION
The MB91121 series is a microcontroller with a 32-bit RISC CPU (FR* family) as the core, incorporating a variety
of I/O resources, a bus control facility, and a multiplier-accumulator (simplified DSP) with internal program RAM
for built-in control applications which require advanced, high-speed CPU processing.
While being based on external bus access for supporting a vast address space accessed by the 32-bit CPU, it
contains 1 K bytes of instruction cache memory and 4 K bytes of RAM (8 K bytes when the DSP is not used) for
speeding up the execution of instructions by the CPU.
In this way, the device is designed for built-in applications which require high performance and processing power
of the CPU, such as digital camera, navigation system, and high-performance FAX, and printer controls.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of Fujitsu Microelectronics Limited.
