3 / 56 page  W742E/C813 Publication Release Date: December 2000 - 3 - Revision A1 1. GENERAL DESCRIPTION The W742E/C813 (W742C813 is mask type, W742E813 is electrical erasable EPROM type) is a high- performance 4-bit microcontroller ( µC) 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) |
