GENERAL DESCRIPTION

TheAPU4006 is a single-chip 4-bit microcontroller with LCD drivers. It can drive up to 3 common time
20 segments, i.e. 60 segments LCD driver. This 4-bit microcontroller contains a 4-bit parallel
processing ALU, 1024 x 15-bit program ROM, 48 x 4-bit data RAM, input ports, alarm driver, timer,
clock generator, crystal and RC oscillator circuit, LCD driver and 70 powerful instructions in a single
chip. It uses HALT instruction to stop all internal operations other than the timer, clock generator,
crystal/RC oscillator and LCD driver. Very low current dissipation can be easily achieved by
combining 4 types of interrupt function and HALT instruction to minimize the operation cycle.

M1 - 4 I Input pins with pull-down Tr or "L-level hold" Tr.

INT I External interrupt request control input pin.

RESET I System reset pin with pull-down resistance.
ALARM O

VDD

VDD1 For Ag-B mode positive power supply pin.
VDD2 For Li-B(EXTV) mode positive power supply pin.

GND Negative power supply pin.

CUP1 - 2 O Pins for connecting voltage step-up (step-down) capacitor.

I

Typical 32.768kHz crystal is connected across OSCIN/OSCOUT for

O

oscillation, R/C oscillation mode is also available.

Output only for outputting 4kHz/2kHz/1kHz modulation signal. Also can be
used to output non-modulation signal.
Power supply pin for logic unit inside LSI. When using Li version, a
capacitor must be connected across GND and VDD to prevent logic unit
from malfunctioning.

Output pins for LCD panel common plate.
The following pins are used in each case.
