Overview
DATA SHEET µPD754202, 754202(A) 4-BIT SINGLE-CHIP MICROCONTROLLERS MOS INTEGRATED CIRCUIT 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 µ PD754202.
Detailed function descriptions, etc.
