Description

The APU4003 is a single chip 4-bit micro-controller with LCD drivers. It can drive up to 3 common times or 25 segments, i.e. a 75-segment LCD driver. This 4-bit micro-controller contains a 4-bit parallel processing ALU, 1024x15-bit program ROM, 64x4-bit data RAM,input/output ports, alarm driver, timer, clock generator,crystal and RC oscillator circuit, LCD driver and 79   powerful instructions in a single chip. The HALT instruction can be used to stop all internal operations other than timer, clock generator, crystal/RC oscillator and LCD driver. Very low current dissipation can be easily achieved by combining 4 kinds of interrupt functions and HALT instruction to minimize the operation cycle.
