ADSP-21161NKCA-100

Digital Signal Processor Dsp Overview

The ADSP-21161NKCA-100 is a 32-bit SHARC digital signal processor featuring a single-instruction multiple-data (SIMD) computational architecture. It operates at a maximum clock frequency of 100 MHz with a core instruction rate up to 110 MHz, delivering peak performance of 660 MFLOPs and sustained performance of 440 MFLOPs. The device integrates 1 Mbit of dual-ported on-chip SRAM, an I/O processor, and an SDRAM controller. Key interfaces include four serial ports supporting I2S, two link ports, an SPI port, and a host interface. It utilizes a 225-ball CSP_BGA package and supports IEEE 32-bit floating-point, 40-bit extended precision, and 32-bit fixed-point data formats.

Digital Signal Processor Dsp Feature Summary

• SIMD Architecture: Two parallel processing elements (PEX and PEY) enable double cycle performance for math-intensive DSP algorithms.
• Integrated Memory: 1 Mbit dual-ported on-chip SRAM allows independent access by the core and I/O processor in a single cycle.
• High Performance: Supports up to 660 MFLOPs peak and 440 MFLOPs sustained performance at 110 MHz core instruction rate.
• Extensive Peripherals: Includes four serial ports (I2S/TDM), two link ports, SPI, DMA controller with 14 channels, and glueless multiprocessing support.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout, temperature range, and voltage specifications. Ensure compatibility with existing board layouts regarding the 225-ball CSP_BGA package dimensions. Confirm that the required clock configuration via CLK_CFG pins meets system timing requirements.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-throughput SIMD processing within a low-cost SHARC derivative. Ensure the design accommodates the 1.71 V to 1.89 V core supply voltage range. Verify that the external memory interface requirements align with the available SDRAM controller and external port capabilities for the target application bandwidth.

Digital Signal Processor Dsp Part Context

The ADSP-21161N is a low-cost derivative of the ADSP-21160, designed to ease code portability from first-generation ADSP-2106x SHARC processors. It maintains source code compatibility in SISD mode while offering enhanced SIMD performance. The part belongs to the ADSP-21161N series, which shares the Super Harvard Architecture common to the SHARC family.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21160NKBZ-100 is a related component in the same family but features a 400-pin BGA package and different power specifications. Direct substitution requires verification of package footprint compatibility and power supply rail adjustments due to differing voltage requirements.
