ADSP-21573KBCZ4D6

ADSP-21573KBCZ4D6 is a device in Analog Devices’ ADSP-2157x SHARC+ DSP family. It is a high-performance 32-bit floating-point digital signal processor designed for real-time audio, communications, and signal-processing tasks. It combines a SHARC+ DSP core with on-chip RAM/ROM, peripheral interfaces, and a memory controller for standalone DSP or embedded processing with a host.
The KBCZ4D6 suffix encodes packaging, temperature rating, and pin count per ADI’s naming conventions (see the datasheet for exact details). Typical capabilities include:
- High-throughput MAC engines and 32-bit floating-point arithmetic
- Streaming peripherals (SPORTs, I2S, SPI), DMA, and timers
- On-chip memory map with external memory interface
- Development support via Analog Devices’ CCES and software libraries
Used for audio codecs, effects processing, high-end filtering, and real-time control tasks. For exact specs, package dimensions, and electrical parameters, consult the ADSP-21573KBCZ4D6 datasheet and packaging guide on Analog Devices’ website.
