DATA SHEET
4-BIT SINGLE-CHIP MICROCONTROLLERS
The
μ
PD750068 is one of the 75XL Series 4-bit single-chip microcontrollers and has a data processing capability
comparable to that of an 8-bit microcontroller.
The
μ
PD750068 provides more CPU functions compared to the 75X Series and realizes high-speed operation
at the low voltage of 1.8 V, making it ideal for battery-driven applications. This device has on-chip A/D converters,
and sophisticated timers capable of operating as a 16-bit timer. The
μ
PD750068(A) has a higher reliability than
the
μ
PD750068.
A version with on-chip one-time PROM,
μ
PD75P0076, is also available for the evaluation during system
development or for small-scale production.
Detailed function descriptions are provided in the following user’s manual. Be sure to read
the document before designing.
