Texas Instruments TMS320C553x Digital Signal Processors

Texas Instruments announced their new TMS320C553x digital signal processors. There are currently four devices: C5532, C5533, C5534 and C5535. The DSP devices feature total active core power of less than 0.15 mW/MHz at 1.05V and standby power of less than 0.15 mW. Pricing of the TI C553x DSPs start at $1.95 (in quantities of 1,000 units). They are ideal for adding signal processing to consumer audio and voice applications, portable medical equipment, biometric security, voice-activated home automation and flow meters.

TI C553x DSP Features

  • 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
  • Active core power at less than 0.15 mW/MHz at 1.05V and standby power at less than 0.15 mW
  • Up to two times lower active power consumption and up to six times lower standby power consumption than the nearest DSP competitor
  • 0.8mm BGA package enables 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
  • Ideal for consumer audio and voice applications, portable medical equipment, biometric security, voice-activated home automation and flow meters
  • Supported by the $55 C5535 eZdsp development kit
