RSV 13

Reserved This pin must be connected directly to VSS for proper

device operation.

RSV 14

Reserved.This pin must be connected directly to 1.8-V I/O

supply

RSV 15

A10

RSV 16

A22

RSV 17

V10

Reserved . Unconnected

RSV 18

Reserved. These pins must be connected directly to 1.8-V I/O

supply(DVDD18) for proper device operation.

RSV 19

Reserved. This pin must be connected to the 1.8-V I/O supply

(DVDD18) via a 200-

Ω resistor for proper device operation.

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

VREFSSTL, RSV19, and RSV20 pins can be directly connected

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 6.3.6.

RSV 20

Reserved. This pin must be connected to ground (VSS) via a

200-

Ω resistor for proper device operation.

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

VREFSSTL, RSV19, and RSV20 pins can be directly connected

to ground (VSS) to save power. However, connecting these

pins directly to ground will prevent boundary scan from

boundary-scan functionality on the DDR2 Memory Controller

pins, see Section 6.3.6.

RSV 21

Y12

Reserved. This pin must be connected via a 20-

Ω resistor

directly to 3.3-V I/O Supply (DVDD33) for proper device

operation. The resistor used should have a minimal rating of

250 mW

RSV 22

W12

Reserved. This pin must be connected via a 40-

Ω resistor

directly to ground (VSS) for proper device operation. The

resistor used should have a minimal rating of 100 mW

TI offers an extensive line of development tools for the TMS320DM64x DMP platform, including tools to

evaluate the performance of the processors, generate code, develop algorithm implementations, and fully

integrate and debug software and hardware modules. The tools support documentation is electronically

available within the Code Composer Studio™ Integrated Development Environment (IDE).

The following products support development of TMS320DM64xx DMP-based applications:

Software Development Tools:

Code Composer Studio™ Integrated Development Environment (IDE): including Editor

C/C++/Assembly Code Generation, and Debug plus additional development tools

Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target

software needed to support any SoC application.

Hardware Development Tools:

Extended Development System (XDS™) Emulator (supports TMS320DM64x DMP multiprocessor

system debug) EVM (Evaluation Module)
