C553x Ultra-Low-Power DSPs

Imagine what you could do with a $2 DSP. You could finally add sophisticated signal processing power to audio and voice applications such as headsets, speakers, smart phone audio accessories and intelligence to your sensor applications at an unprecedented price.

TMS320C553x ultra-low-power DSP generation featuring the lowest power and lowest cost DSP in the industry, starting at $1.95/1 ku, are now available to enable you to do that and much more. Offering the industry's lowest power with active power less than 0.15 mW/MHz at 1.05V and standby power less than 0.15 mW, these highly integrated processors enable developers to get DSP sophistication at a microcontroller price and power consumption.

Features and benefits

  • Four devices- C5532, C5533, C5534 and C5535, each with 50MHz and 100 MHz performance options enable math-intensive algorithms and the ability to run numerically-precise, low-cost, ultra-low-power applications
  • Industry’s lowest total power DSP with total active core power at less than 0.15 mW/MHz at 1.05V and standby power at less than 0.15 mW – up to 6 times lower power consumption than the nearest competition
  • 0.8mm BGA package allows use of four-layer printed circuit board (PCB) to reduce overall system cost
  • Integrated high-speed peripherals: USB 2.0 with PHY, SD/eMMC, I2S, UART, SPI, GPIO
  • On-chip memory options ranging from 64 KB to 320 KB for scalability according to application needs
  • Up to 1024-point programmable fast Fourier transform (FFT) co-processor
  • LCD display controller and 10-bit, four-channel successive approximation (SAR) ADC for intuitive interface
  • 1-3 low-dropout regulators (LDOs) enable integrated power management
