4-BIT SINGLE-CHIP MICROCONTROLLERS

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.

FEATURES

? Key return reset function for keyless entry

? Low-voltage operation: VDD = 1.8 to 6.0 V

? On-chip memory

? Program memory (ROM): 2048 × 8 bits

? Data memory (RAM) : 128 × 4 bits

? Variable instruction execution time useful for high-speed operation and power save

? 0.95, 1.91, 3.81, 15.3 μs (at 4.19-MHz operation)

? 0.67, 1.33, 2.67, 10.7 μs (at 6.0-MHz operation)

? Compact package (20-pin plastic shrink SOP (300 mil, 0.65-mm pitch))

APPLICATIONS

Automotive electronics such as keyless entry units
