DESCRIPTION

The MB90640A 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 2-channel UART serial interface (with extended I/O serial mode) 2-channel PPG, 5-channel 16-bit reload timer, 8-channel chip-select output, and 8-channel external interrupt functions. In addition, the address and data buses can either be non-multiplexed or multiplexed depending on their settings.
