s DESCRIPTION
The MB91110 series is a standard single-chip micro controller featuring various I/O resources and bus control
mechanisms to incorporate the control with required for high performance high-speed CPU processes, having a
32-bit RISC CPU (FR30 series) in its core. Although external bus access is the basis for supporting a large address
space accessible by a 32-bit CPU, a 1-KB instruction cache memory has been built-in to increase the instruction/
execution speed of the CPU.
This unit features the optimal specifications for incorporating applications that require high performance CPU
processing power such as navigation systems, high performance facsimile systems, printer control, etc.
