It delivers 100 dB DAC SNR and 90 dB ADC SNR at 48 kHz for portable digital audio systems requiring low-power playback and recording.
For engineers reviewing the ADSP-BF527KBCZ-5C2 datasheet, ADSP-BF527KBCZ-5C2 pinout, ADSP-BF527KBCZ-5C2 application, or ADSP-BF527KBCZ-5C2 equivalent, key selection factors include its integrated codec's 1.8 V analog/digital supply capability, USB-mode sampling rate support (8–96 kHz), programmable PGA line/mic inputs, and 289-ball CSP_BGA package with validated ball assignment.
Technical Context
The ADSP-BF527KBCZ-5C2 implements a dual-core Blackfin architecture with RISC-like register model and advanced debug/trace features. Its embedded codec includes oversampling Σ-Δ ADCs and DACs, programmable high-pass and de-emphasis filters, and configurable master/slave digital audio interface supporting I²S, left/right-justified, and frame-sync modes.
It integrates a programmable on-chip voltage regulator (exclusive to BF523/BF525/BF527 variants), lockbox secure technology with OTP memory, MMU-based memory protection, and dual-channel memory DMA controllers. Codec clocking supports CODEC_MCLK input (12/24 MHz) or crystal oscillator (XTI/XTO), with selectable CLKDIV2 and CODEC_CLKOUT division options.

FAQ
What is the maximum operating temperature rating for the ADSP-BF527KBCZ-5C2?
The ADSP-BF527KBCZ-5C2 is rated for operation from –40°C to +105°C (industrial extended temperature grade). This K-grade qualification distinguishes it from the B-grade (–40°C to +85°C) variants like ADSP-BF527BBCZ-5C and ensures reliable performance in thermally demanding environments such as automotive infotainment enclosures or industrial edge devices.
Does the ADSP-BF527KBCZ-5C2 include an on-chip voltage regulator?
Yes, the ADSP-BF527KBCZ-5C2 includes a programmable on-chip voltage regulator - a feature exclusive to the ADSP-BF523, ADSP-BF525, and ADSP-BF527 processors within the BF52x family. This regulator enables single-supply operation and dynamic voltage scaling, reducing external power management complexity compared to non-regulator variants like ADSP-BF526KBCZ-5C.
Which audio interface protocols does the ADSP-BF527KBCZ-5C2 codec support?
The ADSP-BF527KBCZ-5C2 codec supports I²S, left-justified, right-justified, and frame-sync (PCM) digital audio protocols - all MSB-first with 16–32-bit word length. Protocol selection is controlled via the FORMAT bits (Register R7, Bits D1:D0), and timing compliance is validated for master and slave configurations per the ADSP-BF52x Rev. A datasheet timing tables.
What are the supported sampling rates in USB mode for the ADSP-BF527KBCZ-5C2?
In USB mode, the ADSP-BF527KBCZ-5C2 supports sampling rates from 8 kHz to 96 kHz using 12 MHz or 24 MHz CODEC_MCLK (with CLKDIV2 enabled). Valid combinations include 44.118 kHz (12.000 MHz / 272), 48 kHz (12.000 MHz / 250), and 96 kHz (12.000 MHz / 125), as specified in Table 2 of the ADSP-BF52x Rev. A datasheet.
How is the ADSP-BF527KBCZ-5C2's microphone input gain configured?
The ADSP-BF527KBCZ-5C2 microphone input uses a two-stage gain architecture: first-stage gain is set by an external resistor (REXT) in series with MICIN (0–14 dB), and second-stage boost is selected via MICBOOST/MICBOOST2 bits (0/20/40 dB). Total gain ranges from 0 dB to 54 dB, with MUTEMIC bit (Register R4, Bit D1) enabling hardware mute independent of gain settings.
