Overview
The MB90660A series of general-purpose, high-performance 16-bit microcontrollers is designed to
provide the high speed real-time processing demanded by a wide variety of industrial and office equipment
as well as process control applications.
The instruction system preserves the AT architecture used in the F2MC-8 series, with the addition of
instructions for use with high-level languages, expanded addressing mode, enhanced multiplication and
division instructions and improved bit processing instructions. Also, the addition of a 32-bit accumulator
enables processing of long-word data.
Peripheral resources include on-chip multi-function timer, 4-channel 16-bit reload timer, 1-channel 8-bit
PWM timer, 1-channel UART, 8-channel 10-bit A/D converter and 8-channel external interrupt functions.
