The μPD753208 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 μPD753208 has an on-chip LCD controller/driver and is based on the μPD75308B of the 75X Series.

However, the μPD75308B is supplied in an 80-pin package, whereas the μPD753208 is supplied in a 48-pin package (375 mils, 0.65-mm pitch) and therefore is suitable for small-scale application systems. In addition, the μPD753208 features expanded CPU functions and performs high-speed operations at a low voltage of 1.8 V.

Features

? Low-voltage operation: VDD = 1.8 to 5.5 V

– Can be driven by two 1.5-V batteries

– 0.67, 1.33, 2.67, 10.7 μs (@ 6.0-MHz operation)

? Internal programmable LCD controller/driver

? Small package:

48-pin plastic shrink SOP (375 mils, 0.65-mm pitch)

? One-time PROM version: μPD75P3216

Applications

Remote controllers, Cameras, Sphygnomamometers, Compact-disc radio cassette player compo systems, gas meters, etc.
