Product details
Overview
ADSP-21479BCPZ-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, asynchronous sample rate converters, and AEC-Q100 qualification for automotive infotainment systems.
For engineers reviewing the ADSP-21479BCPZ-1A datasheet, ADSP-21479BCPZ-1A pinout, ADSP-21479BCPZ-1A application, or ADSP-21479BCPZ-1A equivalent, this page delivers verified technical context, validated pin functions, confirmed audio-peripheral integration (DAI/DPI), real-world timing benchmarks (e.g., 30.59 μs 1024-pt FFT at 300 MHz), and precise package mapping to the 88-lead LFCSP_VQ.
Technical Context
The ADSP-21479BCPZ-1A implements a dual-processing-element SIMD core (PEx/PEy) with independent ALU/multiplier/shifter units, enabling 1.8 GFLOPS at 300 MHz and single-cycle execution of parallel multiply-accumulate operations across both elements. Its enhanced Harvard architecture supports simultaneous 64-bit PM/DM bus transfers and instruction cache–enabled three-bus operation.
It integrates two clock domains: a 300 MHz core domain hosting the SIMD engine and instruction cache, and a peripheral domain with dedicated IOD0/IOD1 buses, DAI peripherals (4 PCGs, S/PDIF Tx/Rx, 4 ASRCs), and DPI peripherals (2 SPI, UART, TWI, 4 PWM). The 88-lead LFCSP_VQ package excludes external port pins but retains full DAI/DPI functionality and thermal diode support.
