Texas Instruments has released two new digital signal processors (DSPs), which it claims to offer up to 320KB of on-chip memory and multiple integrated peripherals that reduce system cost by more than 20%.
The two new DSPs, TMS320VC5505 and TMS320VC5504 with standby power of less than 340uW and active power of less than 0.3mW/MHz are expected to allow up to 40% additional battery life.
The company said that the C5505 DSP, running at 100MHz, is suited for the end equipments such as noise-cancellation headphones, musical instruments, medical monitoring, biometrics and seismic detectors. In addition, the company’s C5504 DSP would also fit for end equipments that do not require as much on-chip memory – portable voice recorders, MP3 players and other emerging portable applications.
TI is also announcing the C5505 DSP EVM that could be used with both the C5505 and C5504 processors. C5504 DSP has up to 256KB of on-chip memory and C5505 builds on C5504 with an additional 64KB on-chip memory.
The TMS320VC5505 is priced at $6.75 and the TMS320VC5504 DSP is priced at $5.60, both in quantities of 1,000 units.
Texas Instruments develops analogue, digital signal processing, RF and DLP semiconductor technologies.
