The TMS320C6747 DSP combines low power and high precision to give designers the freedom to bring portability to audio, medical, industrial and other applications requiring the precision, wide dynamic range and time-to-market benefits of floating-point DSPs. Using three times less power than existing floating-point DSPs in today's market, the C674x devices deliver 24-/32-bit accuracy and are the industry's lowest power floating-point DSPs. Slated for sampling in Q4 2008, the power consumption ranges from 6 mW* in deep-sleep mode to 420 mW** total power in active mode. Key Features:
- Industry's lowest-power floating-point DSPs
- High precision and wide dynamic range enabled through the 24-/32-bit accuracy of the floating-point DSP core
- Portability for traditionally wired applications through low power and rich connectivity peripherals
- Reduces system cost through high feature integration and low pricing starting at less than $11 USD @ 100u quantities
- Up to 20× lower standby power and 1/3 the power consumption of existing floating-point devices
