DESCRIPTION

NO.

SUPPLY VOLTAGE PINS

When RGMII is used, connect to DVDD15 (1.5V/1.8V)

Connected to VSS, if RGMII is not used

NOTE: If the RGMII mode of the EMAC is not used, the DVDD15,

DVDD15MON, VREFHSTL, PTV15P, PTV15N, and HHV15EN pins

HHV15EN

AF13

can be NC or connected directly to VSS (GND) to save power.

However, connecting these pins in this way will prevent

boundary-scan from functioning on the RGMII pins of the EMAC.

To preserve boundary-scan functionality on the RGMII pins, see

Section 7.3.3.

When DDR is used, connect to DVDD18 (1.8V)

Connected to VSS, if DDR is not used

NOTE: If the DDR2 Memory Controller is not used, the DVDD18,

DVDD18MON, VREFSSTL, AVDD3, AVDD4, CVDD1, PTV18P, PTV18N,

HHV18EN

D20

and HHV18EN pins can be NC or connected directly to VSS

(GND) to save power. However, connecting these pins this way

prevents boundary scan from functioning on the DDR2 Memory

Controller pins. To preserve boundary-scan functionality on the

DDR2 Memory Controller pins, see Section 7.3.3.
