4-Bit Micro-Controller with LCD Driver, 1K Word
1/8
FEATURES
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.
