DESCRIPTION
MB90640A series includes 16-bit microcontrollers optimally suitable for process control in a wide variety of
industrial and OA equipment. The series uses the F
2
MC*-16L CPU which is based on the F
2
MC-16 but with
enhanced high-level language and task switching instructions and additional addressing modes.
The internal peripheral resources consist of a 2-channel serial port incorporating a UART function (and
supporting I/O expansion serial mode), 8/16-bit 2-channel PPG, 5-channel 16-bit reload timer, 8-channel chip
select function, and 8-channel DTP/external interrupts.
Also, multiplexed or non-multiplexed operation can be selected for the address/data bus.
*: F
2
MC stands for FUJITSU Flexible Microcontroller.
