APU4003T  
4-Bit Micro-Controller With EPROM, 1K Word  
Features  
yꢀ Very low current dissipation.  
yꢀ Wide operating voltage range.  
yꢀ Supports both Ag and Li batteries.  
yꢀ Powerful instruction set.  
yꢀ 4-level subroutine nesting  
(including interrupt).  
yꢀ Control outputs: ALARM, LIGHT.  
yꢀ LCD driver outputs  
(can drive up to 75 LCD segments).  
yꢀ PROM 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 event-driven interrupts, 2 external and 2  
internal.  
yꢀ PROM option permits LCD driver output pins to  
be used for DC output ports; up to 25 pins are  
available.  
yꢀ ROM size: 1024x15 bits.  
yꢀ RAM size: 64x4 bits.  
yꢀ Segment PLA circuit permits any layout on LCD  
panel.  
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 Built-in clock generator (crystal or RC).  
yꢀ Built-in voltage doubler, halver, tripler.  
yꢀ Endurance: More then 100 write cycles/word.  
yꢀ Security bit for read/write protection.  
General Description  
The APU4003T is an EEPROM-equipped high- performance 4-bit microcomputer.  
It contains not only all functions compatible with APU4003T, but also an EEPROM, providing customers such  
conveniences as on-board verification,  
customized code, small quantity sample production, etc.  
This chip especially provides a security bit to protect the customer’s code.
