DATA SHEET
MOS INTEGRATED CIRCUIT
µPD754302,754304,754302(A),754304(A)
4-BIT SINGLE-CHIP MICROCONTROLLER
The µPD754304 is one of the “75XL Series” 4-bit single-chip microcontrollers with data processing capability
comparable to that of 8-bit microcontrollers. The µPD754303(A) has a higher reliability than the µPD754304.
The microcontrollers in the 75XL Series have expanded CPU functions than those of the 75X Series and can
operate at a voltage of as low as 1.8 V; therefore, they are ideal for battery-driven application systems.
As the one-time PROM version of the µPD754304, the µPD75P4308 is ideal for evaluation of a system under
development or for small-scale production of application systems.
Detailed information about functions can be found in the following document. Be sure to read the following
document before designing.
µPD754304 User’s Manual: U10123E
FEATURES
• Low-voltage operation: VDD = 1.8 to 5.5 V
• Internal memory
Program memory (ROM):
2048 × 8 bits (µPD754302, 754302(A))
4096 × 8 bits (µPD754304, 754304(A))
Data memory (RAM): 256 × 4 bits
• Variable instruction execution time effective for high-
speed operation and power saving
0.95, 1.91, 3.81, or 15.3 µs (at 4.19 MHz)
0.67, 1.33, 2.67, or 10.7 µs (at 6.0 MHz)
• Internal serial interface (1 channel)
• Powerful timer function (3 channels)
• Inherits instruction set of existing 75X Series for easy
replacement
APPLICATIONS
µPD754302, 754302(A)
Cordless telephones, TVs, VCRs, audio systems, household appliances, office machines, etc.
µPD754304, 754304(A)
Automotive appliance, etc.
The µPD754302 and 754304 differ from the µPD754302(A) and 754304(A) only in terms of their quality grade.
Unless otherwise specified, the µPD754304 is treated as a representative model in this Data Sheet.
For the models other than the µPD754304, µPD754304 can be read as the other model name.
If different descriptions are made for the µPD754302 and 754304, the (A) models correspond as follows:
µPD754302 µPD754302(A), µPD754304 µPD754304(A)
