C553X Ultra-Low-Power DSP Value Line

Texas Instruments' TMS320C5532, TMS320C5533, TMS320C5534 and TMS320C55835 are extremely low cost, low power 16-bit processors which help conserve energy at exceptional levels and enable longer battery life. With 240 MIPS performance, up to 320 KB on-chip memory, higher integration (including a hardware accelerator for FFT computation) than comparable devices, the C553x product generation provides a foundation for a range of signal processing applications, including voice and audio recorder, musical instruments, portable medical solutions and other consumer electronics in industrial and security applications.


  • Four devices, (C5532, C5533, C5534 and C5535) each with 50 MHz and 100 MHz performance options, enable math-intensive algorithms and the ability to run numerically-precise, low-cost, ultra-low-power applications
  • The industry’s lowest total power DSP, with total active core power at less than 0.15 mW/MHz at 1.05 V and standby power at less than 0.15 mW – up to six times lower power consumption than the nearest competition
  • 0.8 mm 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, and 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
