DESCRIPTION
μ
PD78366A is provided with a high-speed, high-performance CPU and powerful operation functions.  Unlike the
existing 
μ
PD78328, 
μ
PD78366A 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, 
μ
PD78P368A, is also available.
Detailed functions, etc. are described in the following user’s manual.  Be sure to read the manual to design systems.
