GENERAL DESCRIPTION

W83601R/G/W83602R/G are general purpose input/output ICs with SMBusTM( I2C ). W83601R/G provides 15 GPI/O pins. W83602R/G provides 10 GPI/O pins and ACPI power control function for STR.

W83601R/G/W83602R/G 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/G)
