Low power DSPs from Texas Instruments offer up to 40 percent additional battery life for voice, biometrics, medical and other portable devices
To meet the power levels needed for the latest portable designs, Texas Instruments today announced the availability of the TMS320VC5505 and TMS320VC5504 digital signal processors (DSPs), which offer the best combination of standby and active power, up to 320 KB of on-chip memory and multiple integrated peripherals that reduce system cost by more than 20 percent.
With standby power of less than 340uW and active power of less than 0.3mW/MHz, these DSPs allow up to 40 percent additional battery life.
The C5505 DSP, running at 100 MHz, offers the right combination of performance, standby and active power levels for end equipments such as noise-cancellation headphones, musical instruments, medical monitoring, biometrics and seismic detectors. For end equipments such as portable voice recorders, MP3 players and other emerging portable applications that do not require as much on-chip memory, an integrated display controller or FFT hardware acceleration, the C5504 DSP provides an even lower cost solution. The lower cost C5504 is pin-to-pin and software compatible with the C5505 device and offers the same power efficiency and performance with a reduced peripheral set.
To help customers get started quickly, TI is also announcing the C5505 DSP EVM that can be used with both the C5505 and C5504 processors and comes ready with application demos and code.
