I/O Controller Hub 6 (ICH6) Family Datasheet
Note: Loaded from EEPROM. If EEPROM contains either 0000h or FFFFh in the device ID location,
VccLAN3_3 (mobile only) must power up before VccLAN1_5 (mobile only) or after VccLAN1_5
within 0.7 V. VccLAN1_5 must power down before VccLAN3_3 or after VccLAN3_3 within
0.7 V.
3.3 V/2.5 V Power Sequencing Requirements
For platforms that use the integrated 2.5 V regulator, there are no power sequencing requirements
for associated 3.3 V/2.5 V rails of the ICH6.
For platforms that use an external 2.5 V regulator to power Vcc2_5 of the ICH6 (the internal
voltage regulator is disabled), the platform must ensure that Vcc3_3 must power up before Vcc2_5
or after Vcc2_5 within 0.7 V.
Vcc1_5/V_Processor_IO Power Sequencing Requirements
Vcc1_5 must power up before V_CPU_IO or after V_CPU_IO within 0.3 V. V_CPU_IO must
power down before Vcc1_5 or after Vcc1_5 within 0.7 V.
then 266Ch is used. Refer to the ICH6 EEPROM Map and Programming Guide for LAN Device
IDs.
