upd753208/upd753206/upd753204

The mPD753204, 753206, and 753208 is a 4-bit single-chip microcontroller of the 75XL series that features a data processing ability equivalent to that of 8-bit microcontrollers.
The mPD753208 adopts a 48-pin package (375 mil, 0.65-mm pitch) suitable for small scale system, while the existing 75X series product with LCD controller/driver adopts an 80-pin package. In addition, CPU extension and high-speed operation at 1.8-V low voltage are realized, compared to the existing mPD75308B.
