GENERAL DESCRIPTION
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 driver, six 4-bit I/O ports (including 1 output port for LED driving), and one channel DTMF generator.
There are also five interrupt sources and 16-levels subroutine nesting for interrupt applications.
The W742E81A/W742C81A operates on very low current and has two power reduction modes, that is the dual-clock slow operation and STOP mode, which help to minimize power dissipation.
