ADSP-BF524KBCZ-4C2

Digital Signal Processor Dsp Overview

The ADSP-BF524KBCZ-4C2 is a Blackfin embedded processor featuring an integrated low-power stereo audio codec. It operates at up to 600 MHz with a RISC-like architecture and includes 132 KB of on-chip memory. The device supports external SDRAM and asynchronous memories via a glueless controller. Key features include flexible booting from SPI, TWI, or UART, Lockbox Secure Technology for code security, and two dual-channel DMA controllers. The package is a 289-ball CSP_BGA (12 mm x 12 mm).

Digital Signal Processor Dsp Feature Summary

• Integrated stereo audio codec with 24-bit ADCs/DACs, supporting sampling rates from 8 kHz to 96 kHz.
• Up to 600 MHz high-performance Blackfin processor core with RISC-like instruction model.
• 132 KB on-chip memory with two dual-channel DMA controllers.
• External memory controller supporting SDRAM and asynchronous 8/16-bit memories.

Digital Signal Processor Dsp Applications

• Portable digital audio applications requiring high-quality stereo playback and recording.
• USB audio devices utilizing specific master clock frequencies (12 MHz or 24 MHz).
• Embedded systems needing secure boot options and code protection via Lockbox technology.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'C2' against the official Analog Devices ordering guide to confirm temperature range and packaging variations. Ensure compatibility with the published ADSP-BF52x data sheet for general specifications, as this document details only the codec differences. Confirm RoHS compliance status through manufacturer documentation.

Digital Signal Processor Dsp Selection Notes

Select this component when both high-performance DSP processing and integrated high-fidelity audio conversion are required in a single chip. Consider the 289-ball CSP_BGA package constraints for PCB layout. Evaluate power consumption requirements, noting the codec can operate at 7 mW for stereo playback at 1.8 V.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF52xC series, which extends the standard ADSP-BF52x Blackfin family by adding an embedded low-power audio codec. It shares the core processor architecture and peripheral set of the BF52x series but adds dedicated analog audio interfaces and control registers for the codec functionality.

Digital Signal Processor Dsp Replacement Considerations

Standard ADSP-BF524 processors lack the embedded codec. Verify if the application requires the integrated audio DAC/ADC or if external components are acceptable. If the codec is unnecessary, a standard BF524 variant may offer cost or availability advantages.

Digital Signal Processor Dsp FAQ

What are the supported digital audio sampling rates?

The codec supports sampling rates from 8 kHz to 96 kHz, including standard rates like 44.1 kHz and 48 kHz, as well as USB-specific rates like 44.118 kHz and 48 kHz.

How is the codec control interface configured?

The codec uses a 2-wire (TWI) or 3-wire (SPI) interface selected by the CMODE pin. TWI mode uses addresses 0011010 or 0011011 based on the CSB pin state.

What is the maximum input level for the ADC?

The maximum full-scale input level for the ADC is 1.0 Vrms when AVDD is 3.3 V. Exceeding this level causes data overloading and audible distortion.
