1. GENERAL DESCRIPTION
The W742E/C813 (W742C813 is mask type, W742E813 is electrical erasable EPROM type) is a high-
performance 4-bit microcontroller (
μ
C) that built in 640-dot LCD driver. The device contains a 4-bit
ALU, two 8-bit timers, two dividers in dual-clock operation, a 40
×
16 LCD driver, ten 4-bit I/O ports
(including 2 output port for LED driving), multiple frequency output, and one channel DTMF generator.
There are also eleven interrupt sources and 16-level stack buffer. The W742E/C813 operates on very
low current and has three power reduction modes, hold mode, stop mode and slow mode, which help
to minimize power dissipation.
2. FEATURES
Operating voltage
2.4V – 5.5V for mask type
2.4V - 4.8V for electrical erasable EPROM type
Dual-clock operation
Main oscillator
3.58 MHz or 400 KHz can be selected by code option
Crystal or RC oscillator can be selected by code option
Sub-oscillator
Connect to 32.768 KHz crystal only
Memory
32768(32K) x 16 bit program ROM (including 64K x 4 bit look-up table)
5120(5K) x 4 bit data RAM (including 16 nibbles x 16 pages working registers)
40 x 16 LCD data RAM
40 input/output pins
Port for input only: 3 ports/12 pins
Input/output ports: 3 ports/12 pins
High sink current output port for LED driving: 2 port /8 pins
DC output port: 2 ports/ 8 pins (selected by code option)
Power-down mode
Hold mode: no operation (main oscillator and sub-oscillator still operate)
Stop mode: no operation (main oscillator and sub-oscillator are stopped)
Slow mode: main oscillator is stopped, system is operated by the sub-oscillator (32.768 KHz)
