APU4003  
4-Bit Micro-Controller With LCD Driver, 1K Word  
Features  
yꢀ Very low current dissipation  
yꢀ Wide operating voltage range  
yꢀ Control outputs: ALARM, LIGHT  
yꢀ LCD driver outputs  
yꢀ Supports both Ag and Li batteries  
yꢀ Powerful instruction set  
(can drive up to 75 LCD segments)  
yꢀ Mask option to select 4 LCD drive modes: static,  
duplex (1/2 duty 1/2 bias, 1/3 duty 1/2 bias or 1/3  
duty 1/3 bias)  
yꢀ 4-level subroutine nesting (including interrupt)  
yꢀ 4 event driven interrupts, 2 external and 2  
internal

yꢀ Input ports: 2 ports/8 pins (S and M)  
yꢀ Output port: 1 port/4 pins (P)  
yꢀ Pseudo serial output port (P)  
yꢀ Input/output ports: 2 ports/8 pins (I/OA and I/OB)  
yꢀ Segment PLA circuit permits any layout on LCD  
panel  
yꢀ Built-in clock generator (crystal or RC)  
yꢀ Built-in voltage doubler, halver, tripler  
General Description  
The APU4003 is a single chip 4-bit micro-controller with powerful instructions in a single chip. The HALT  
LCD drivers. It can drive up to 3 common times or 25  
segments, i.e. a 75-segment LCD driver. This 4-bit  
micro-controller contains a 4-bit parallel processing  
ALU, 1024x15-bit program ROM, 64x4-bit data RAM,  
instruction can be used to stop all internal operations  
other than timer, clock generator, crystal/RC oscillator  
and LCD driver. Very low current dissipation can be  
easily achieved by combining 4 kinds of interrupt  
input/output ports, alarm driver, timer, clock generator, functions and HALT instruction to minimize the  
crystal and RC oscillator circuit, LCD driver and 79  
operation cycle.
