The µPD750068 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 µPD750068 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 µPD750068(A) has a higher reliability than the µPD750068.
