W83601R/602R
Preliminary
1. GENERAL DESCRIPTION
The W83601R/602R are general purpose input/output ICs with SMBusTM. W83601R provides 15
GPI/O pins. W83602R provides 9 GPI/O pins and ACPI power control function for STR.
W83601R/602R both provides SMBusTM address setting pins to set the address during power- on
reset or from external reset.
W83601R SMBusTM Address is :
0 0 1 1 A2 A1 A0 R/W
W83602R SMBusTM Address is :
0 0 1 1 0 A1 A0 R/W
W83601R/602R also provides a interrupt to inform system that a transition occurs on General
Purpose(GP) input pins.
2. FEATURES
