The
µPD754202 is a member of the 75XL Series of 4-bit single-chip microcontrollers that enable data processing
equivalent to that of an 8-bit microcontroller.
It features expanded CPU functions compared to the 75X Series and enables high-speed, low-voltage operation
at 1.8 V, making it suitable for battery-driven applications.
The
µPD754202(A) is a higher-reliability product compared to the µPD754202.
Detailed function descriptions, etc., are provided in the following user’s manual. Be sure to read it
when designing.
µPD754202 User’s Manual: U11132E
