ADSP-21369KBPZ-3A

Digital Signal Processor Dsp Overview

The ADSP-21369KBPZ-3A is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements (PEx, PEy). The core operates at a maximum instruction rate of 400 MHz, delivering up to 2.4 GFLOPS. On-chip memory includes 2 Mbits of SRAM and 6 Mbits of mask-programmable ROM. Key peripherals include an S/PDIF transceiver, four asynchronous sample rate converters, eight serial ports, and a digital applications interface (DAI). The device supports shared memory configurations in the 256-ball BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix KBPZ-3A against the manufacturer's current data sheet to confirm package type, temperature range, and security key status. Ensure compatibility with existing design files if replacing earlier revisions. Check for moisture sensitivity levels and recommended soldering profiles during procurement planning.

Digital Signal Processor Dsp Selection Notes

Select this component when high-density floating-point arithmetic is required alongside dedicated audio interfaces. The 256-ball BGA package enables shared memory support, which is critical for multiprocessor architectures. Consider the 6 Mbits of ROM for secure boot code storage using the 64-bit JTAG key feature. Evaluate pin count requirements as the LQFP_EP variant lacks shared memory support.

Digital Signal Processor Dsp Part Context

The ADSP-21369 belongs to the third-generation SHARC family, offering improved performance over previous models like the ADSP-21367. It maintains source code compatibility with ADSP-2126x and ADSP-2116x processors. The K-series designation typically indicates extended industrial temperature ranges compared to commercial variants.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21367 and ADSP-21368 are obsolete models removed from the Rev H datasheet. Direct pin-compatible replacements within the same family may require software adaptation due to peripheral differences. Verify that any substitute supports the required 400 MHz clock speed and SIMD architecture.
