UPD750068

DATA SHEET MOS INTEGRATED CIRCUIT µPD750064, 750066, 750068, 750064(A), 750066(A), 750068(A) 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 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. A version with on-chip one-time PROM, µPD75P0076, 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.
