The W541L203 W541L202 W541L205 W541L204 is a high-performance 4-bit Microcontroller (C) that operates on very low current. The device contains a 4-bit ALU, two 8-bit Timers a divider, a serial port, and five 4-bit I/O ports (including 3 output ports for LED driving). There are also seven interrupt sources and 8-level subroutine nesting for interrupt applications. The W541E/C/L20X has two power reduction modes, hold mode and stop mode, which help to minimize power dissipation. The W541L203 W541L202 W541L205 W541L204 is suitable for remote controllers, toy controllers, keyboard controllers, speech synthesis LSI controllers, and other products.
