4-BIT SINGLE-CHIP MICROCONTROLLER
The
碌
PD754304 is one of the 鈥?5XL Series鈥?4-bit single-chip microcontrollers with data processing capability
comparable to that of 8-bit microcontrollers. The
碌
PD754303(A) has a higher reliability than the
碌
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
碌
PD754304, the
碌
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.

PD754304 is treated as a representative model in this Data Sheet.
For the models other than the
碌
PD754304,
碌
PD754304 can be read as the other model name.
