1. GENERAL DESCRIPTION
The W742S82A is a high-performance 4-bit micro controller (
μ
C) 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 of subroutine nesting for interrupt
applications. The W742S82A operates on very low current and has two power reduction modes, are
the dual-clock slow operation and STOP mode, which help to minimize power dissipation.
