Preliminary W742E81A/W742C81A  
4-BIT MICROCONTROLLER  
1. GENERAL DESCRIPTION  
m
The W742E81A/W742C81A is a high-performance 4-bit microcontroller ( 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 40 4 LCD driver, six 4-bit I/O ports (including 1 output port for LED driving), and  
one channel DTMF generator. There are also five interrupt sources and 16-levels subroutine nesting  
for interrupt applications. The W742E81A/W742C81A 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.  
2. FEATURES  
-
· Operating voltage: 2.4V 3.8V  
· Dual-clock operation or single-clock operation (By option)  
· Main-oscillator  
-
-
-
Connect to 3.58 MHz crystal or 400 KHz that can be selected by option code  
Crystal or RC oscillator can be selected by code option (W742E81A)  
Connect to 2 MHz typical RC oscillator (W742C81A)  
· Sub-oscillator  
-
Connect to 32768 Hz crystal only  
· Memory  
-
-
-
16384 x 16 bits program flash EEPROM (including 64K x 4 bit look-up table)  
2048 x 4 bits data RAM (including 16 nibbles x 16 pages working registers)  
40 x 4 LCD data RAM  
· 24 input/output pins  
-
-
-
-
Port for input only: 1 ports/4 pins(RC)  
Input/output ports: 3 ports/12 pins(RA, RB & RD)  
High sink current output port for LED driving: 1 port /4 pins(RE)  
Port for output only: 1 port/ 4 pins(RF)  
· Power-down mode  
-
-
-
Hold function: no operation (main-oscillator and sub-oscillator still operate)  
Stop function: no operation (main-oscillator and sub-oscillator are stopped)  
Dual-clock slow operation mode: system is operated by the sub-oscillator (F  
stopped)  
OSC  
=Fs and Fm is  
· Five types of interrupts  
-
-
Four internal interrupts (Divider0, Divider1, Timer 0, Timer 1)  
One external interrupts (RC Port)
