4 Bit Microcontroller

The W742C814 is a high-performance 4-bit micro-controller (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 32 4 LCD Driver five 4-bit I/O ports (including 1 output port for LED driving), and one channel DTMF generator. There are also five interrupt sources and 8-levels subroutine nesting for call subroutine or interrupt applications. The W742C814 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.
