MTU429B (Preliminary) GENERAL DESCRIPTION The MTU429B is an embedded high performance 4-bit microcomputer 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. 4-Bit Micro-Controller with LCD Driver • • • • • • • • • • • • • BLOCK DIAGRAM SEG35~SEG38 SEG31~SEG34 SEG39~SEG42 SEG27~SEG30 COM1~8 ...
