Description

The W741L260 is a high-performance 4-bit microcontroller (mC) with an LCD driver. The device contains a 4-bit ALU, two 8-bit timers, two dividers, a 32 ´ 4 LCD driver, and five 4-bit I/O ports (including one high sink current output port). There are also five interrupt sources and 8-level subroutine nesting for interrupt applications. The W741L260 has one power reduction mode to help minimize power dissipation.

The W741L260 has two oscillator circuits and can work in dual-clock or single-clock operation mode. It is suitable for handheld games, watches, clocks, speech synthesis LSI controllers, and other products.
