DATA SHEET

MOS INTEGRATED CIRCUIT

µPD754202, 754202(A)

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.

Detailed function descriptions, etc., are provided in the following user’s manual. Be sure to read it

when designing.

µPD754202 User’s Manual: U11132E

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

The µPD754202 and µPD754202(A) have different quality grades. Unless otherwise specified, descriptions in
