Terminal Functions (Ground and Power Supply) (continued) TERMINAL NO TYPE(1) INTERNAL OPER DESCRIPTION NAME PULLUP/ VOLT PULLDOWN DVDD18 E5 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 F8 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 F14 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 F16 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 F18 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 G9 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 G11 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 G13 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 G15 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 G17 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 H10 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 H12 1.8-V I/O supply voltage (DDR2 Memory Controller) DVDD18 H14 1.8-V I/O supply voltage (DDR2 Memory Controller) DDR_VREF C11 (DVDD18/2)-V reference for SSTL buffer (DDR2 Memory Controller0. This input voltage cn be generated directly from DVDD18 using two 1-KΩ resistors to form a resister divider circuit. VCCMON L19 Die-side 1.2-V core supply voltage monitor pin. The monitor pins indicate the voltage on the die, and, therefore, provide the best probe point for voltage monitoring purposes. If the VCCMON pin is not used, it should be connected directly to the 1.2-V core supply or left unconnected. VDD18MON B2 Die-side 1.8-V I/O supply voltage monitor pin. The monitor pins indicate the voltage on the die and, therefore, provide the best probe point for voltage monitoring purposes. If the VDD18MON pin is not used, it should be connected directly to the 1.8-V I/O supply (DVDD18). VDD33MON G21 Die-side 3.3-V I/O supply voltage monitor pin. The monitor pins indicate the voltage on the die and, therefore, provide the best probe point for voltage monitoring purposes. If the VDD33MON pin is not used, it should be connected directly to the 3.3-V I/O supply (DVDD33). Reserved RSV 1 L20 A Reserved. Unconnected RSV 2 L21 A Reserved. Unconnected RSV 3 D2 O Reserved.

These pins must be connected directly to VSS for proper device operation. RSV 8 H8 A Reserved. These pins must be connected directly to VSS for proper device operation. RSV 9 M2 A Reserved. Unconnected RSV 10 A2 A Reserved. Unconnected RSV 11 E2 Reserved This pin must be connected directly to VSS for proper device operation. RSV 12 E1 Reserved. This pin must be connected directly to 1.8-V I/O supply RSV 13 E4 Reserved This pin must be connected directly to VSS for proper device operation. RSV 14 E3 Reserved. This pin must be connected directly to 1.8-V I/O supply Copyright © 2007–2012, Texas Instruments Incorporated Device Overview 33 Submit Documentation Feedback Product Folder Link(s): TMS320DM647 TMS320DM648 |
