W83601R_06 Datasheet, PDF (3/21 Pages) Winbond – Winbond GPI/O IC

W83601R/G/W83602R/G
1. GENERAL DESCRIPTION
W83601R/G/W83602R/G are general purpose input/output ICs with SMBus^TM( 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 SMBus^TM (I²C) address setting pins to set the address during
power- on reset or from external reset.
W83601R/G SMBus^TM Address is:
0 0 1 1 A2 A1 A0 R/W
W83602R/G SMBus^TM 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.
