Part No.	W541L480
Datasheet	W541L480.pdf
Description	The W541L480 are high-performance 4-bit microcontroller (uC) with an LCD driver and mask ROM for the program memory. The device contains a 4-bit ALU, two 8-bit timers, two dividers, a 32x4 LCD driver, and five 4-bit I/O ports (including 1 output port to drive the LEDs). There are also five interrupt sources and 8-level subroutine nesting for interrupt applications. The W541L480 have two power reduction modes, hold mode and stop mode, which help to minimize power dissipation. The W541L480 have two oscillator circuits and can work in dual-clock or single-clock operation mode. It is suitable for remote controllers, watches and clocks, hand-held games and other products.
Features	Operating voltage: 1.2V to 3.6V (LCD drive voltage: 3.0V or 4.5V) ‧ Operating frequency 4MHz: 1.5V~3.6V 1MHz: 1.2V~3.6V ‧Single or Dual Clock Mode ‧Memory  4096 x 16 bit program ROM (including 4K  4 bit look-up table)  256 x 4 bit data RAM (including 16 working registers)  32 x 4 LCD data RAM ‧ 21 input/output pins ‧ Power-down mode ‧ LCD driver output 32 segment x 4 common ‧ MFP output pin ‧ Two built-in 8-bit programmable countdown timers ‧ Built-in 18/14-bit watchdog timer selectable for system reset
