DESCRIPTION
Reserved. Unconnected
Reserved. Unconnected
Reserved. These pins must be connected directly to 1.8-V I/O
supply(DV_DD18) for proper device operation.
Reserved. This pin must be connected to the 1.8-V I/O supply
(DV_DD18) via a 200-Ω resistor for proper device operation.
NOTE: If the DDR2 Memory Controller is not used, the
DDR_VREF, RSV19, and RSV20 pins can be directly
connected to ground (V_SS) 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.

Reserved. This pin must be connected via a 20-Ω resistor
directly to 3.3-V I/O Supply (DV_DD33) for proper device
operation. The resistor used should have a minimal rating of
250 mW.
Reserved. This pin must be connected via a 40-Ω resistor
directly to ground (V_SS) for proper device operation. The
resistor used should have a minimal rating of 100 mW.
2.7 Device Support
2.7.1 Development Support
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 multiprocessor system
debug) EVM (Evaluation Module)
For a complete listing of development-support tools for the TMS320DM64x platform, visit the Texas
Instruments website at www.ti.com. For information on pricing and availability, contact the nearest TI
field sales office or authorized distributor.
