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

Reserved . Unconnected

RSV 16

A22

Reserved . Unconnected

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,

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)
