4 Rev.A.03 K8 Timing ControllerATPA02 n Pin Description Pin No. Pin Name I/O Type Function

1 VDD_GD INt

Active-High of this signal indicates VDD voltage is valid. This signal is usually connected to the power-good output of the PWM for CPU core voltage

2 VLDT_SEN INa

This pin is used to detect the ClawHammer VLDT (1.2V) power or power-good signal.

3 VDDA_SEN INa

This pin is used to detect the ClawHammer VDDA (2.5V) power or power-good signal.

4 VDIMM_SEN INa

This pin is used to detect the VDIMM (2.5V/1.8V) power or power-good signal.

5 SB_PSON# INt

Active low. This signal is connected to the PSON# signal from the SB or Super I/O to control the on/off of ATX power supply.

6 ACPI_S3 INt

Active high. This signal indicates that the system is in S3 state.

7 ATX_PWRGD INt

Active-High of this signal indicates all of the voltage from the ATX power supply is valid.

8 GND Ground

9 ATX_PSON# OD70

Active low. This pin is used to control the on/off of ATX power supply. Active-Low of this signal will turn on the ATX power supply. This pin is open-drain output and should be pulled-up via a resistor to 5VSB externally.

10 RST_BTN# INt

Active low. This function is panel reset botton input with de-bounce circuit.

11 CPU_PWRGD OD70

Active high. This signal is connected to the Claw Hammer to indicate all system powers are valid. This pin is open- drain output and should be pulled-up externally via a resistor to 2.5V. I/O Type Function INt TTL level input INa Analog input OD70 Open-drain with 70mA sink current
