Product details

Overview

ADSP-21479KBCZ-1A from Analog Devices is a 32-bit/40-bit floating-point SHARC® DSP optimized for high-performance audio processing, operating at up to 300 MHz with 5 Mbits of on-chip SRAM and 4 Mbits of ROM, supporting SIMD computation, S/PDIF transceiver, and AEC-Q100 qualification for automotive infotainment systems.

For engineers reviewing the ADSP-21479KBCZ-1A datasheet, ADSP-21479KBCZ-1A pinout, ADSP-21479KBCZ-1A application, or ADSP-21479KBCZ-1A equivalent, key selection criteria include its 196-ball CSP_BGA package, real-time clock (RTC), watchdog timer, thermal diode, and support for FIR/IIR/FFT acceleration in audio decoder and motor control implementations.

Technical Context

The ADSP-21479KBCZ-1A implements a dual-processing-element SIMD core (PEx/PEy) with independent ALU, multiplier, and shifter units per element, enabling 1.8 GFLOPS at 300 MHz. It features two 64-bit data buses (PMD/DMD) and a 48-bit instruction word supporting VISA compression for code density.

Its peripheral architecture includes a digital applications interface (DAI) with four precision clock generators (PCG), eight serial ports (SPORT), four asynchronous sample rate converters (ASRC), and an S/PDIF transceiver - all accessible via dedicated DAI routing pins and supported only in the 196-ball CSP_BGA package.

FAQ

What is the maximum operating frequency of the ADSP-21479KBCZ-1A?

The ADSP-21479KBCZ-1A operates at up to 300 MHz, delivering 1.8 GFLOPS peak performance in SIMD mode. This frequency is achieved using an internal PLL locked to an external differential clock input (CLKIN), and is validated across the full industrial temperature range (−40°C to +85°C) for AEC-Q100 Grade 3 compliance.

Does the ADSP-21479KBCZ-1A support SDRAM interfacing?

Yes, the ADSP-21479KBCZ-1A supports glueless SDRAM interfacing via its dedicated SDRAM controller, but only in the 196-ball CSP_BGA package. It supports up to four banks with 62M words in Bank 0 and 64M words in Banks 1–3, enabling large audio buffer expansion beyond the 5 Mbits of on-chip SRAM.

Which audio codecs are pre-programmed in the ADSP-21479KBCZ-1A's ROM?

The ADSP-21479KBCZ-1A's 4 Mbits of on-chip ROM contains factory-programmed, licensed audio decoders from Dolby and DTS. These include Dolby Digital (AC-3), Dolby Digital Plus, and DTS Coherent Acoustics - accessible directly at boot without external flash loading, subject to IP licensing agreements.

Is the ADSP-21479KBCZ-1A pin-compatible with other SHARC processors?

No, the ADSP-21479KBCZ-1A is not pin-compatible with earlier SHARC families due to its 196-ball CSP_BGA package and unique peripheral mapping. It shares code compatibility with ADSP-2146x/2147x devices, but hardware design requires dedicated layout for thermal diode, RTC_CLKOUT, and SDRAM signals not present in LQFP or LFCSP variants.

What development tools are supported for the ADSP-21479KBCZ-1A?

The ADSP-21479KBCZ-1A is fully supported by Analog Devices' CrossCore Embedded Studio IDE, including C/C++ compiler with VISA optimization, SHARC simulator, and EZ-KIT Lite evaluation hardware (ADZS-21479-EZLITE). Debugging uses JTAG with 64-bit key authentication enabled for secure ROM-based designs.
