4 Bit Microcontroller

The W742E/C811 W742C811 is mask type, W742E811 is electrical erasable EPROM type) is a high- performance 4-bit Microcontroller (mC) that built in 640-dot LCD Driver The device contains a 4-bit ALU, two 8-bit Timers two dividers in dual-clock operation, a 40 16 LCD Driver ten 4-bit I/O ports (including 2 output port for LED driving), multiple frequency output, and one channel DTMF generator. There are also eleven interrupt sources and 16-level stack Buffer The W742E/C811 operates on very low current and has three power reduction modes, hold mode, stop mode and slow mode, which help to minimize power dissipation.
