Dallas, Tex. - Texas Instruments Incorporated's TMS320C5504 and TMS320C5505 ultra-low-power digital signal processors (DSPs) run at 150 MHz, providing 25 percent higher performance than previous C55x devices,allowing designers to create energy-efficient portable and battery-powered applications at higher levels of performance.
The C5504 and C5505 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.
The C5504 DSP provides a low-cost solution with the right combination of performance and standby and active power levels for emerging portable applications that require up to 256 kB on-chip memory, such as portable voice recorders and MP3 players. The C5504 features highly-integrated high-speed USB 2.0, I2S, UART, SPI, MMC/SD and GPIOs, 256 kB of on-chip memory, and a 16-bit dual-MAC CPU.
The C5505 DSP builds on the C5504 by adding an additional 64 kB on-chip memory, an integrated display controller and fast Fourier transform (FFT) hardware acceleration for end equipments such as noise-cancellation headphones, musical instruments, medical monitoring, biometrics and seismic sensors. The C5505 builds on the C5504 with an additional 64 kB on-chip memory (320kB total) and features an up to 1024-point programmable FFT hardware accelerator. In addition to peripherals supported by the C5504, the C5505 supports an LCD display controller and 10-bit 4-channel successive approximation (SAR) ADC.
Both devices are pin-to-pin and software compatible, offering the same energy efficiency and performance with a different peripheral set. This allows system designers to develop one platform that bridges different price markets by migrating between processors.

The TMS320C5504 DSP is priced at $6.20 in quantities of 1,000 units (1 ku). Both devices are sampling now. The TMS320C5505 is priced at $7.45 US in quantities of 1,000 units.
