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 48-
pin 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.
