■ DESCRIPTION

The MB91191/192 series is a single-chip microcontroller using a 32-bit RISC-CPU (FR series) as its core. It contains peripheral I/O resources suitable for software servo control in applications such as VTRs that require high-speed CPU processing.

■ FEATURES

CPU

? 32-bit RISC (FR series) , load/store architecture, 5-stage pipeline
