MB91110 is a standard single-chip microcontroller having a 32-bit RISC CPU (FR30
Series) as its core. This microcontroller contains I/O resources and bus control
features for built-in control that require high-performance, high-speed CPU
processing. External bus access is basically used to support a wide address space
accessed by the 32-bit CPU. For high-speed CPU instruction processing, however, a
1KB instruction cache is built in.
The specifications make the microcontroller optimum for use a navigation system, a
high-performance facsimile, or a printer requiring high CPU processing performance.
