General 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.
