'C54x reference design
The prototype integrates a wide range of TI parts into a 200-MIPS multipurpose board geared toward general telecommunications, networking and telephony applications. It will allow developers to gain insight into what they should and should not do in the manufacturing process. Interested designers and developers can download full schematics and a manual outlining the reference design from TI website The reference design centers around two 100-MIPS 'C549 DSPs in the 144-ball microStar BGA package. The space-saving microStar package measures 12 x 12 x 1.4 mm, thereby reducing board space over similar pin-count thin quad flat packs (TQFP). Each 'C549 DSP uses a dual power supply to increase performance and lower power dissipation. The reference platform uses TI power-supply management devices to handle the separate I/O and core power supplies. For designers who prefer TI's TQFP, the reference board also includes a layout for the 176-pin TQFP option of the recently disclosed 'C5410 DSP. This added feature enables the same development environment to be used for either the 'C549 or 'C5410 DSPs. microStar is a trademark of Texas Instruments.

TI's 'C54x dual-board reference design capitalizes on the increased density of the microStar BGA package and provides a mechanism for developers to understand the specifics of designing with the 'C549 microStar BGA before committing resources to creating dedicated hardware using these devices.
