■ DESCRIPTION
MB90610A series includes 16-bit microcontrollers optimally usable for high-speed real-time data processing in consumer appliances and for system control of printer, CD-ROM, celluar phone, copier, etc. The series uses the *F2MC-16L CPU which is based on the F2MC-16 but with enhanced high-level language and task switching instructions and additional addressing modes.
The internal peripheral resources consist of a 3-channel serial port incorporating a UART function (and supporting I/O expansion serial mode), 8-channel 10-bit A/D converter, 2-channel PPG, 2-channel 16-bit reload timer, 8-channel chip select output, and 8-channel external interrupts.
Also, multiplexed or non-multiplexed operation can be selected for the address/data bus.
