W742C(E)811  
4-BIT MICROCONTROLLER  
1. GENERAL DESCRIPTION  
The W742C(E)811 [W742C811 is mask type, W742E811 is MTP(Multiple Time Program)  
type] is a high-performance 4-bit microcontroller (mC) 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 1 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 MTP type  
· Dual-clock operation  
· Main oscillator  
- 3.58MHz or 400khz can be selected by code option  
- crystal or RC oscillator can be selected by code option  
· Sub-oscillator  
- Connect to 32.768KHz 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: 1 port /4 pins  
- Port for output only: 1 port/ 4 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  
(32.768KHz)
