MB90246A Series

s FEATURES

• Clock

Operating clock can be selected from divided-by-2, 4, 8 or 32 of oscillation (at oscillation of 32 MHz, 1 MHz

to 16 MHz).

Minimum instruction execution time of 62.5 ns (at machine clock of 16 MHz)

• CPU addressing space of 16 Mbytes

Internal addressing of 24-bit

External accessing can be performed by selecting 8/16-bit bus width (external bus mode)

• Instruction set optimized for controller applications

Rich data types (bit, byte, word, long word)

Rich addressing mode (23 types)

High code efficiency

Enhanced precision calculation realized by the 32-bit accumulator

Signed multiplication/division instruction

• Instruction set designed for high level language (C) and multi-task operations

Adoption of system stack pointer
