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.

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.

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.
