GENERAL DESCRIPTION

TheAPU4006is 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.

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.
