Datasheet APU4003T Datasheet (APLUS)

4-Bit Micro-Controller With EPROM, 1K Word

APU4003T

Features

y Very low current dissipation.
y Wide operating voltage range.
y Supports both Ag and Li batteries.
y Powerful instruction set.
y 4-level subroutine nesting

(including interrupt).

y 4 event-driven interrupts, 2 external and 2

internal.

y ROM size: 1024x15 bits.
y RAM size: 64x4 bits.
y Input ports: 2 ports/ 8 pins (S and M).
y Output port: 1 port/ 4 pins (P).
y Pseudo serial output port (P).
y Input/Output ports: 2 ports/ 8 pins

(I/OA and I/OB).

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,

y Control outputs: ALARM, LIGHT.
y LCD driver outputs

(can drive up to 75 LCD segments).

y 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).

y PROM option permits LCD driver output pins to

be used for DC output ports; up to 25 pins are
available.

y Segment PLA circuit permits any layout on LCD

panel.

y Built-in clock generator (crystal or RC).
y Built-in voltage doubler, halver, tripler.
y Endurance: More then 100 write cycles/word.
y Security bit for read/write protection.

customized code, small quantity sample production, etc.
This chip especially provides a security bit to protect the customer’s code.
