Preliminary W742C(E)811
- 4 -
1. GENERAL DESCRIPTION
The W742C(E)811 [W742C811 is mask type, W742E811 is Flash (Multiple Time Program) 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 8bit timers, two dividers in dual-clock operation, a 40
×
16 LCD driver, ten 4bit 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 W742C(E)811 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 - 6.0V for mask type
2.4V - 4.8V for FLASH 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
16384(16K) 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)
