The uPD753104, 753106, and 753108 are members of NEC’s new 75XL series of 4-bit single-chip microcontrollers.
The existing model in the 75X Series with LCD controller/driver uses an 80-pin package, but the mPD753104, 753106,
and 753108 employ a 64-pin package suitable for small-scale systems. In addition, a super small plastic TQFP (12 x 12
mm), which makes a substantial contribution to miniaturization of the LCD panel, is also available.
