General Description
APU429 General Description
The APU429 is an embedded high performance4-bit micro-computer with an on-chip LCD driver. It contains all the necessary functions in a single chip:4-bit parallel processing ALU, ROM, RAM, I/O ports,timer, clock generator, dual clock, RFC, EL-light,LCD driver, look-up table, watchdog timer and keyboard scanning. The instruction set includes not only 4-bit operation and manipulation instructions but also various conditional branch instructions and LCD driver data transfer instructions which are powerful and easy to use.The HALT function stops any internal operations other than the oscillator, divider and LCD driver in order to minimize the power dissipation.The STOP function stops all the clocks in the chip.
