Description

The W541L250 is fully compatible with W741L250 in the terms of pin assignment and IC functon except main oscillator. It is a high-performance 4-bit microcontroller (µC) that provides an LCD driver. The device contains a 4-bit ALU, two 8-bit timers, a divider, a 24 × 4 LCD driver, and five 4-bit I/O ports (including 1 output port for LED driving). There are also five interrupt sources and 8-level subroutine nesting for interrupt applications. The W541L250 operates on low voltage and very low current and has two power reduction modes, hold mode and stop mode, which help to minimize power dissipation.

The W541L250 is suitable for remote controllers, watches and clocks, multiple I/O products, keyboard controllers, speech synthesis LSI controllers, and other products.
