APU4006
4-Bit Micro-Controller with LCD Driver, 1K Word
Very low current dissipation. Wide operating voltage range. Supports both Ag and Li batteries. Powerful instruction set. 4-level subroutine nesting (including interrupt). 4 event driven interrupts, 2 external and 2 internal. ROM size: 1024 x 15 bits. RAM size: 48 x 4 bits. Input ports: 1 port/ 4 pins (M-PORT). Control output: ALARM. LCD driver outputs (can drive up to 60 LCD segments). Mask option to select 3 LCD drive modes: static, duplex 1/2 duty 1/2 bias, 1/3 duty 1/2 bias. Mask option permits LCD driver output pins to be used for DC output ports. Up to 20 pins are available. SEG13-SEG20 can be selected by open-drain output. Segment PLA circuit permits any layout on the LCD panel. Built-in clock generator (crystal or RC). Built-in voltage doubler, halver.
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.

Name OSCIN OSCOUT M1 - 4 INT RESET ALARM VDD VDD1 VDD2 GND CUP1 - 2 Type I O I I I O Description Typical 32.768kHz crystal is connected across OSCIN/OSCOUT for oscillation, R/C oscillation mode is also available. Input pins with pull-down Tr or "L-level hold" Tr. External interrupt request control input pin. System reset pin with pull-down resistance. 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. For Ag-B mode positive power supply pin. For Li-B(EXTV) mode positive power supply pin. Negative power supply pin. Pins for connecting voltage step-up (step-down) capacitor. Output pins for LCD panel common plate. The following pins are used in each case. Static O
