MOS INTEGRATED CIRCUIT
µPD78363A,78365A,78366A,78368A
16/8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
µPD78366A is provided with a high-speed, high-performance CPU and powerful operation functions. Unlike the
existing µPD78328, µPD78366A is also provided with a high-resolution PWM signal output function which
substantially contributes to improving the performance of the inverter control.
A PROM model, µPD78P368A, is also available.
Detailed functions, etc. are described in the following user’s manual. Be sure to read the manual to design systems.
