Part No.	W541L250
Datasheet	W541L250.pdf
Description	The W541L250 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 x 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 W541C/L250 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 W541C/L250 is suitable for remote controllers, watches and clocks, multiple I/O products, keyboard controllers, speech synthesis LSI controllers, and other products.
