4-BIT SINGLE-CHIP MICROCOMPUTER

The µPD75316B is a 75X Series 4-bit single-chip microcomputer capable of the same data processing as an 8- bit microcomputer.
It is a low-voltage operation version of the µPD75316 with an on-chip LCD controller/driver. Operation at an ultra-low voltage of 2.0 V is possible. An ultra small-sized plastic TQFP (12 x 12 mm) is also provided and it is suitable for small-sized sets that use an LCD panel.

FEATURES
• Ultra-low-voltage operation possible: VDD = 2.0 to 6.0 V
   • Can be driven by two 1.5-V manganese batteries.
• On-chip memory
