NAME NO.
SUPPLY VOLTAGE MONITOR PINS
Die-side 1.2-V core supply (CVDD) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
CVDDMON N1 and other voltage monitoring pins, see the TMS320TCI6482 Design Guide and
Comparisons to TMS320TCI100 application report (literature number
SPRAAC7). If the CVDDMON pin is not used, it should be connected directly to
the 1.2-V core supply (CVDD).
Die-side 3.3-V I/O supply (DVDD33) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
DVDD33MON L6 and other voltage monitoring pins, see the TMS320TCI6482 Design Guide and
Comparisons to TMS320TCI100 application report (literature number
SPRAAC7). If the DVDD33MON pin is not used, it should be connected directly to
the 3.3-V I/O supply (DVDD33).
Die-side 1.5-/1.8-V I/O supply (DVDD15) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
and other voltage monitoring pins, see the TMS320TCI6482 Design Guide and
Comparisons to TMS320TCI100 application report (literature number
SPRAAC7). If the DVDD15MON pin is not used, it should be connected directly to
DVDD15MON F3 I the 1.5-/1.8-V I/O supply (DVDD15).
NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, DVDD15MON,
VREFHSTL, RSV13, and RSV14 pins can be connected directly to ground (VSS)
to save power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see Section 8.3.4.
Die-side 1.8-V I/O supply (DVDD18) voltage monitor pin. The monitor pins
indicate the voltage on the die and, therefore, provide the best probe point for
voltage monitoring purposes. For more information regarding the use of this
DVDD18MON A26 and other voltage monitoring pins, see the TMS320TCI6482 Design Guide and
Comparisons to TMS320TCI100 application report (literature number
SPRAAC7). If the DVDD18MON pin is not used, it should be connected directly to
the 1.8-V I/O supply (DVDD18).
SUPPLY VOLTAGE PINS
(DVDD18/2)-V reference for SSTL buffer (DDR2 Memory Controller). This input
voltage can be generated directly from DVDD18 using two 1-kΩresistors to form
a resistor divider circuit.
NOTE: The DDR2 Memory Controller is not used, the VREFSSTL, RSV11, and
VREFSSTL C14 A RSV12 pins can be connected directly to ground (VSS) to save power.
However, connecting these pins directly to ground will prevent boundary-scan
from functioning on the DDR2 Memory Controller pins. To preserve boundary-
scan functionality on the DDR2 Memory Controller pins, see Section 8.3.4.
(DVDD15/2)-V reference for HSTL buffer (EMAC RGMII). VREFHSTL can be
generated directly from DVDD15 using two 1-kΩresistors to form a resistor
divider circuit.
NOTE: If the RGMII mode of the EMAC is not used, the DVDD15, VREFHSTL,
VREFHSTL B2 A RSV13, and RSV14 pins can be connected to directly ground (VSS) to save
power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see Section 8.3.4.
1.8-V I/O supply voltage (SRIO regulator supply).
DVDDR AD20 S NOTE: If Rapid I/O is not used, this pin can be connected directly to VSS.
AC15 SRIO analog supply:
1.25-V I/O supply voltage (-1000 and -1200 devices)
AC17
AVDDA A 1.2-V I/O supply voltage (-850 devices).
Do not use core supply.
AD16 NOTE: If Rapid I/O is not used, these pins can be connected directly to VSS.
AVDLL1 A13 A 1.8-V I/O supply voltage.
