NO.

G24

H23

J24

K23

K25

L24

M23

DVDD33

3.3-V I/O supply voltage

W24

Y23

1.2-V supply voltage for DDR EMIF

NC or connected to VSS, if DDR is not used

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

F11

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

CVDD1

and HHV18EN pins can be NC or connected directly to VSS

F13

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

K11

prevents boundary scan from functioning on the DDR2 Memory

Controller pins. To preserve boundary-scan functionality on the

K13

DDR2 Memory Controller pins, see Section 7.3.3.

N20

1-V (500-MHz device), 1.1-V (625-MHz device), 1.2-V (700-MHz

device) supply voltage for SRIO core logic

P19

NC or connected to VSS, if RapidIO is not used

R20

NOTE: If the RapidIO interface is not used, the CVDD2, AVDDA,

CVDD2

DVDDD, DVDDR, and AVDDT pins can be NC or connected directly

T19

to VSS (GND) to reduce power use. However, connecting these

pins in this way prevents boundary scan from functioning on the

U20

RapidIO pins. To preserve boundary-scan functionality on the

RapidIO pins, see Section 7.3.3.

R24

1.2-V RapidIO analog supply voltage

NC or connected to VSS, if RapidIO is not used

Do not connect this SERDES supply to CVDD1

NOTE: If the RapidIO interface is not used, the CVDD2, AVDDA,

AVDDA

DVDDD, DVDDR, and AVDDT pins can be NC or connected directly

U24

to VSS (GND) to reduce power use. However, connecting these

pins in this way prevents boundary scan from functioning on the

RapidIO pins. To preserve boundary-scan functionality on the

RapidIO pins, see Section 7.3.3.

AVDDA1

M29

1.8-V System PLL analog supply voltage

AVDDA2

AG14

1.8-V EMAC PLL analog supply voltage
