4-BIT SINGLE-CHIP MICROCONTROLLER
The
μ
PD754304 is one of the “75XL Series” 4-bit single-chip microcontrollers with data processing capability
comparable to that of 8-bit microcontrollers. The
μ
PD754303(A) has a higher reliability than the
μ
PD754304.
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
μ
PD754304, the
μ
PD75P4308 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.

The
μ
PD754302 and 754304 differ from the
μ
PD754302(A) and 754304(A) only in terms of their quality grade.
Unless otherwise specified, the
μ
PD754304 is treated as a representative model in this Data Sheet.
For the models other than the
μ
PD754304,
μ
PD754304 can be read as the other model name.
If different descriptions are made for the
μ
PD754302 and 754304, the (A) models correspond as follows:
