TMS320C5532AZAYA10

Digital Signal Processor Dsp Overview

The TMS320C5532AZAYA10 is a fixed-point digital signal processor based on the C55x DSP core, operating at a maximum clock rate of 100 MHz with a 10-ns instruction cycle time. It features 64 KB of dual-access RAM (DARAM) and 128 KB of single-access ROM (SAROM). The device includes four DMA controllers with 16 channels total, four I2S interfaces, two SD/eMMC interfaces, SPI, I2C, and UART. It utilizes a 144-terminal BGA package and supports isolated power domains for analog, CPU, and peripheral sections.

Digital Signal Processor Dsp Feature Summary

• C55x Fixed-Point DSP Core: 100 MHz operation with up to 200 Million Multiply-Accumulates per second
• Memory Configuration: 64 KB DARAM and 128 KB SAROM
• Peripheral Interface Set: Four I2S modules, two SD/eMMC interfaces, SPI, I2C, and UART
• Power Management: Three integrated LDOs (ANA_LDO, DSP_LDO, USB_LDO) supporting isolated power domains

Digital Signal Processor Dsp Applications

• Wireless Audio Devices (Headsets, Microphones)
• Voice Applications
• Portable Medical Devices
• Industrial Controls

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'A10' against the manufacturer's current datasheet revision to confirm the 100 MHz speed grade and voltage specifications. Ensure the package type matches the required PCB footprint for the 144-terminal BGA array. Check for any lead-free or RoHS compliance documentation relevant to the manufacturing batch.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance audio processing is required within a low-power constraint. The absence of an onboard USB PHY distinguishes it from higher-tier models like the C5535 or C5534; external USB solutions are necessary if that interface is needed. Verify that the 64 KB SARAM capacity meets application memory requirements, as this model lacks the larger SARAM found in other variants.

Digital Signal Processor Dsp Part Context

This component belongs to the Texas Instruments TMS320C553x family of fixed-point DSPs. It shares the same C55x core architecture and pinout as the C5533, C5534, and C5535 but offers reduced on-chip SRAM and omits the USB 2.0 High-Speed PHY and FFT hardware accelerator found in more expensive variants.
