General Instructions
The w83l603g and w83l604g are general purpose input/output integrated circuits with smbustm. The W83L603G model provides 8 GPI/O pins, and the W83L604G provides 14 GPI/O pins. Both W83L603G and W83L604G provide smbustm address setting pins to set the address during power-on reset or external reset. The W83L603G/W83L604G smbustm address is: W83L603G and W83L604G also provide an interrupt to notify the system that a conversion occurs on a dedicated input pin in general. With W83L603G and W83L604G, blinking LED output and beeper functions are also supported. Part numbers marked with a "G" are lead-free packaged products.
