s DESCRIPTION
The MB91150 is a single-chip microcontroller using a RISC-CPU (FR 30 series) as its core. It contains peripheral
I/O resources suitable for audio, MD and so on which are required to operate at low power consumption.
s FEATURES
1. CPU
• 32-bit RISC (FR30) , load/store architecture, 5-stage pipeline
• General-purpose registers: 32 bits ×16
• 16-bit fixed-length instructions (basic instructions) , 1 instruction/ 1 cycle
• Memory-to-memory transfer, bit processing, barrel shift processing : Optimized for embedded applications
• Function entrance/exit instructions, and multiple load/store instructions of register contents, instruction systems
supporting high level languages
