CRIPTION The µPD753017A is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability comparable to that of an 8-bit microcontroller. It has an on-chip LCD controller/driver with a larger ROM capacity and extended CPU functions compared with the conventional µPD75316B, and can provide high-speed operation at a low supply voltage of 1.8 V. It can be supplied in a small plastic TQFP package (12 × 12 mm) and is suitable for small sets using LCD panels. Detailed descriptions of functions are provided in the following document. Be sure to read the document before designing. µPD753017 Use
