Texas Instruments announces industry's lowest power DSPs, now running at 150 MHz performance

Texas Instruments TMS320C5504 TMS320C5505

Texas Instruments Incorporated announced the availability of TMS320C5504 and TMS320C5505 ultra-low-power digital signal processors (DSPs) at 150 MHz, providing 25 percent higher performance than previous C55x devices.

Texas Instruments: TMS320C5504, TMS320C5505

The C5504 and C5505 processors offer the industry’s lowest total power at less than 0.15 mW/MHz and standby power at less than 0.15 mW. The processors feature up to 320 KB of on-chip memory and multiple integrated peripherals that reduce system cost by more than 20 percent compared to earlier C55x processors. Dynamic voltage and frequency scaling can be used to maximize the battery life for different operating conditions, allowing up to 40 percent additional battery life compared to earlier C55x processors.
