DATA SHEET µPD753204, 753206, 753208 4-BIT SINGLE-CHIP MICROCONTROLLERS MOS INTEGRATED CIRCUIT The µ PD753208 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 µ PD753208 has an on-chip LCD controller/driver and is based on the µ PD75308B of the 75X Series. However, the µ PD75308B is supplied in an 80-pin package, whereas the µ PD753208 is supplied in a 48pin package (375 mils, 0.65-mm pitch) and therefore is suitable for small-scale application systems. In addition, the µ PD753208 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. µ PD753208 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 ( µ PD753204) 6144 × 8 bits ( µ PD753206) 8192 × 8 bits ( µ PD753208) – 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 µ s (@ 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: µ PD75P3216 Applications Remote controllers, Cameras, Sphygnomamometers, Compact-disc radio cassette player compo systems, gas meters, etc. Ordering Information Part number Package 48-pin plastic shrink SOP (375 mils, 0.65-mm pitch) 48-pin plastic shrink SOP (375 mils, 0.65-mm pitch) 48-pin plastic shrink SOP (375 mils, 0.65-mm pitch) ROM (× 8 bits) 4096 6144 8192 µ PD753204GT-××× µ PD753206GT-××× µ PD753208GT-××× Remark ××× indicates ROM code suffix.
