Texas Instruments announces industry’s lowest power DSPs, now running at 150 MHz performance
New TMS320C5504/05 ultra-low-power DSPs offer 25 percent higher performance while reducing system cost by more than 20 percent, targeting portable and battery-powered applications
Bangalore (September 9, 2010) – Allowing designers to create energy-efficient portable and battery-powered applications at higher levels of performance, Texas Instruments Incorporated (TI) recently 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.
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.
CC2533: Key features and benefits:
- On-chip memory: Offers options of 64-KB and 96-KB in-system programmable Flash optimized for ZigBee RF4CE applications; provides pin-compatible upgrade path to CC2531 with 256 KB of Flash and USB interface.
- Low power: Four flexible power modes offer lowest current consumption, including a 1-uA sleep mode, allowing up to 10 times longer battery life compared to IR-based remote controls.
- Best performance: Device integrates a best-in-class transceiver with a typical receiver sensitivity of
-97 dBm and output power of 7 dBm.
- Rich peripheral set: 5-channel DMA, 23 GPIOs, 2 USARTs, SPI, I2C and 4 timers allows for additional system integration with user interface, reducing overall system BOM.
- Free stack: TI offers a free, downloadable software stack, RemoTI network protocol, reference designs and tools to ensure customers have everything needed for system development.

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 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.
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.
