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

• Internal memory

   – Program memory (ROM):

      4096 × 8 bits (µPD753204)

      6144 × 8 bits (µPD753206)

      8192 × 8 bits (µPD753208)

   – Data memory (RAM): 512 × 4 bits

• Variable instruction execution time for high-speed operation and power saving operation

   – 0.95, 1.91, 3.81, 15.3 µs (@ 4.19-MHz operation)

   – 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.
