W541L23X

Note: Exposure to conditions beyond those listed under Absolute Maximum Ratings may adversely affect the life and reliability of the device.

The W541L23x is high-performance 4-bit microcontroller (C) that provides an LCD driver. The device contains a 4-bit ALU, two 8-bit timer, two dividers, a 16 * 4 LCD driver, and three 4-bit I/O ports. There are also three interrupt sources and 8-level subroutine nesting for interrupt applications. The W541L23x has two power reduction modes, hold mode and stop mode, which help to minimize power dissipation.

The W541L23x has two oscillator circuits and can work in dual-clock or single-clock operation mode. It is suitable for remote controllers, watches and clocks, speech synthesis LSI controllers, hand-held games and other products.
