DATA SHEET
MOS INTEGRATED CIRCUIT
µPD753204, 753206, 753208
4-BIT SINGLE-CHIP MICROCONTROLLERS
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.
Detailed information about functions can be found in the following user’s manual. Be sure to read it
before designing. µPD753208 User’s Manual: U10158E
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.
