UPD750064 4-BIT SINGLE-CHIP MICROCONTROLLERS

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.
