Signal Names and Descriptions
31.1
Overview
This chapter provides a detailed description of the signals and bootstrap definitions for
the SoC. The signals are arranged in functional groups according to their associated
interface.
Each signal description table has the following headings:
• Signal: The name of the signal ball/pin.
• Description: A brief explanation of the signal function.
• Power Rail: Power rails used to supply power to the I/O signal are defined in
• Description: A brief explanation of the signal function.
• Power Rail: Power rails used to supply power to the I/O signal are defined in
.
Table 31-1. Buffer Power Rails
Power Rail
Description
V1P0A
1.00V Suspend (SUS) rail. This rail is active in the S5 power state.
V1P0S
1.00V Core rail. This rail is inactive in the S5 power state, but powered in S0.
V3P3A
3.3V SUS rail. This rail is active in the S5 power state.
V3P3S
3.3V Core rail. This rail is inactive in the S5 power state, but powered in S0.
VRTC3P0
3.3V RTC Power rail
VDDQ
DDR3 I/O Voltage (1.5V/1.35V)
Note:
Using VDDQA and VDDQB instead of a single VDDQ is based on the DIMM topology.
When the DIMMs are on either side of the SoC, VDDQA and VDDQB are used for
Channel 0 and Channel 1 respectively.
Note:
Refer to
for more details on the voltage rails.
