GENERAL DESCRIPTION
The W83601R/W83602R are general purpose input/output ICs with SMBusTM( I2C ). W83601R provides 15 GPI/O pins. W83602R provides 9 GPI/O pins and ACPI power control function for STR.
W83601R/W83602R both provides SMBusTM (I2C) address setting pins to set the address during power- on reset or from external reset.

FEATURES
• SMBus compliance with 3.3V voltage levels
• Two ports GPI/O which provides more flexibility
• Issue interrupts to notify system that an event occurs
• GP output can be level or pulse mode
• Interrupt output can be level or pulse mode
• Internal power-on reset or external RST# pin reset
• Programmable POWER LED output
• ACPI power management for Suspend to Ram (STR) (only for W83602R)
