TMS320C5534NZAY10

Digital Signal Processor Dsp Overview

The TMS320C5534NZAY10 is a fixed-point digital signal processor based on the C55x core, operating at up to 100 MHz with a 10-ns instruction cycle time. It features 64 KB of dual-access RAM (DARAM) and 192 KB of single-access RAM (SARAM), alongside 128 KB of ROM. The device includes four DMA controllers with 16 channels total, USB 2.0 high-speed PHY, two SD interfaces, four I2S modules, and an RTC. Power management utilizes three integrated LDOs for analog, DSP, and USB domains.

Digital Signal Processor Dsp Feature Summary

• C55x DSP CPU with dual MAC units and parallel bus architecture
• 256 KB total on-chip RAM (64 KB DARAM + 192 KB SARAM)
• USB 2.0 High-Speed Device mode with integrated PHY
• Four DMA controllers providing 16 independent data transfer channels

Digital Signal Processor Dsp Applications

• Wireless audio devices such as headsets and speakerphones
• Voice applications and echo cancellation headphones
• Portable medical devices
• Industrial controls and software-defined radio

Digital Signal Processor Dsp Procurement Notes

Verify that the 'N' suffix in the part number corresponds to the industrial temperature range (-40°C to +85°C) as defined by Texas Instruments nomenclature. Confirm package availability for the 144-terminal BGA array. Ensure power supply sequencing adheres to the manual's guidelines for the isolated DSP_LDO, ANA_LDO, and USB_LDO domains.

Digital Signal Processor Dsp Selection Notes

Select this model over the TMS320C5533 if 192 KB of SARAM is required, or over the TMS320C5535 if the FFT hardware accelerator and SAR ADC are not needed. The A10 speed grade supports 100 MHz operation at 1.3 V. Verify that the system design accommodates the specific voltage requirements for the 1.05 V (50 MHz) and 1.3 V (100 MHz) core domains.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C553x family of low-power fixed-point DSPs. It shares the same 144-pin BGA package and base C55x architecture as the C5532, C5533, and C5535. Key differentiators include its specific memory configuration (64 KB DARAM/192 KB SARAM) and the inclusion of USB 2.0 connectivity without the FFT accelerator found in the C5535.

Digital Signal Processor Dsp Replacement Considerations

TMS320C5534AZHH10: Same device family with standard commercial temperature range instead of industrial.
