Power Rail Descriptions for Intel® 600 Series Chipset Family PCH

Name

Description

VCCPRIM_​CORE_​0P82

Primary Core Voltage: 0.82 V

VCCPRIM_​0P82

Primary Well Voltage: 0.82 V

VCCPRIM_​1P05

Primary Well Voltage: 1.05 V

VCCDUSB_​0P82

USB digital logic voltage: 0.82 V

VCCHSIO_​0P82

HSIO Supply Voltage: 0.82 V

VCCAHSIOPLL_​1P8 Analog supply for HSIO PLLs: 1.8 V
VCCA_​XTAL_​PLL_​1P8 Analog supply for XTAL circuit: 1.8 V
VCCA_​XTAL_​PLL_​0P82 Analog supply for XTAL circuit: 0.82 V

VCCDSW_​3P3

Deep Sx Well Voltage: 3.3 V

VCCPRIM_​1P8

Primary Well: 1.8 V

VCCPRIM_​3P3

Primary Well: 3.3 V

VCCSPI

SPI Voltage: 3.3 V or 1.8 V.

DCPRTC This rail is generated internally and needs to be routed out to the motherboard for decoupling purpose.

VCCRTC

RTC Well Supply. This rail can drop to 2.0 V if all other planes are off. This power is not expected to be shut off unless the RTC battery is removed or drained.

Notes:
  1. VCCRTC nominal voltage is 3.0 V. This rail is intended to always come up first and always stay on. It should NOT be power cycled regularly on non-coin battery designs.
  2. Implementation should not attempt to clear CMOS by using a jumper to pull VCCRTC low. Clearing CMOS can be done by using a jumper on RTCRST# or GPI.

DCPCNVILDO1

This rail is generated internally and needs to be routed out to the motherboard for decoupling purpose.

DCPCNVILDO2

This rail is generated internally and needs to be routed out to the motherboard for decoupling purpose.

VCCPGPPA

Power rail for GPIOs (3.3 V or 1.8 V).

VCCPGPPBC

Power rail for GPIOs (3.3 V or 1.8 V).

VCCPGPPD

Power rail for GPIOs (3.3 V or 1.8 V).

VCCPGPPEFK

Power rail for GPIOs (3.3 V or 1.8 V).

VCCPGPPGH

Power rail for GPIOs (3.3 V or 1.8 V).

VCCPGPPIR

Power rail for GPIOs (3.3 V or 1.8 V).

VSS

Ground
