s DESCRIPTION

The MB91F155A/MB91155/MB91154 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

• Register interlock functions, efficient assembly language description

• Branch instructions with delay slots : Reduced overhead time in branching executions

• Internal multiplier/supported at instruction level

Signed 32-bit multiplication : 5 cycles

Signed 16-bit multiplication : 3 cycles

• Interrupt (PC and PS saving) : 6 cycles, 16 priority levels
