* Operating voltage: 2.4V−3.8V
* Dual-clock operation or single-clock operation (By option)
* Main-oscillator − Connect to 3.58 MHz crystal or 400 KHz that ca.

The W742E81A/W742C81A operates on very low current and has two power reduction modes, that is the dual-clock slow opera.

4-BIT MICROCONTROLLER The W742E81A/W742C81A is a high-performance 4-bit microcontroller (µC) that provides an LCD driver. The device contains a 4-bit ALU, two 8-bit timers, two dividers (for two oscillators) in dual- clock operation, a 40 × 4 LCD d.
