DATA SHEET MOS INTEGRATED CIRCUIT µPD753304 4-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µPD753304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability parable to that of an 8-bit microcontroller. Since it inherits the 75X series CPU, it has upward patibility. While the conventional 75X series products with an on-chip LCD controller/driver use an 80-pin package, the µPD753304 is sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function, etc. For detailed function descriptions, refer to the following user’s manual. µPD753304 User’s Manual: U12020E Features - RC oscillation...
