ADSP-BF523KBCZ-5C2

Digital Signal Processor Dsp Overview

The ADSP-BF523KBCZ-5C2 is a Blackfin Embedded Processor with an integrated stereo audio codec, operating at up to 600 MHz. It features a RISC-like architecture, 132 KB of on-chip memory, and a programmable on-chip voltage regulator. The embedded codec includes 24-bit ADCs and DACs, supporting sampling rates from 8 kHz to 96 kHz. Key electrical specifications include a DAC SNR of 100 dB (A-weighted) and THD of –80 dB at 48 kHz with a 3.3 V supply. The device utilizes a 289-ball CSP_BGA package (12 mm x 12 mm) and supports external memory interfaces for SDRAM and asynchronous memories.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KBCZ-5C2 against Analog Devices official documentation to confirm pinout, temperature range, and package variant. Ensure compatibility with the ADSP-BF52xC revision A datasheet for codec-specific register configurations and timing requirements.

Digital Signal Processor Dsp Selection Notes

Select this component when a combined DSP and audio codec solution is required in a single package. The ADSP-BF523C variant specifically includes the programmable on-chip voltage regulator, which simplifies power design compared to variants without this feature. Confirm that the 132 KB on-chip memory meets application constraints before choosing over larger memory variants.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF52xC family, which extends the standard ADSP-BF52x series by adding an embedded stereo audio codec. The 'C' designation indicates the presence of the codec functionality, distinguishing it from the base ADSP-BF52x processors. This integration reduces board space and component count for audio-centric designs.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include ADSP-BF522C, ADSP-BF524C, ADSP-BF525C, ADSP-BF526C, and ADSP-BF527C. Selection depends on memory size, peripheral availability, and whether the programmable voltage regulator is required. Verify pin compatibility across the BF52xC series.

Digital Signal Processor Dsp FAQ

What are the supported audio sampling rates?

The codec supports sampling rates of 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz.

How is the codec control interface configured?

The control interface can operate as either a 2-wire TWI or 3-wire SPI interface, selected by the state of the CMODE pin.

What is the maximum full-scale input level for the ADC?

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