W83601R/G/W83602R/G

1. 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.

W83601R/G SMBusTM Address is:

0 0 1 1 A2 A1 A0 R/W

W83602R/G SMBusTM Address is:

0 0 1 1 0 A1 A0 R/W

W83601R/G/W83602R/G also provides a interrupt to inform system that a transition occurs on General

Purpose (GP) input pins.

2. FEATURES
