ADSP-21160NCB-100

Digital Signal Processor Dsp Overview

The ADSP-21160NCB-100 is a high-performance 32-bit floating-point digital signal processor from the SHARC family, manufactured by Analog Devices. It operates at a core instruction rate of 100 MHz with a 10 ns cycle time. The device features a Super Harvard architecture with four independent buses for dual data fetch, instruction fetch, and I/O. It includes two computational processing elements (PEX and PEY) supporting single-instruction multiple-data (SIMD) operations, providing up to 200 million fixed-point MACs sustained performance. The processor integrates 4 Mbits of on-chip dual-ported SRAM, an I/O processor with DMA capabilities, and various interfaces including serial ports, link ports, and a host port.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'NCBZ' or 'NCB' against the manufacturer's current ordering guide to ensure package type and lead-free compliance match requirements. Confirm that the '100' suffix corresponds to the 100 MHz speed grade. Check for RoHS compliance status as manufacturing processes may update component specifications over time.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21160N variant over the ADSP-21160M for higher performance (100 MHz vs 80 MHz) and lower power consumption due to the 0.18 micron CMOS process. Ensure the application requires SIMD processing capabilities to utilize the dual computational units effectively. Verify that the system design supports the required 3.3 V I/O and 1.9 V core voltage levels specified for the N series.

Digital Signal Processor Dsp Part Context

The ADSP-21160x family belongs to the SHARC DSP line, which is backward assembly-compatible with the ADSP-2106x series in SISD mode. The ADSP-21160N represents an advancement in the SHARC architecture, offering improved throughput through SIMD processing compared to its predecessors. It is designed for applications requiring high-speed mathematical computations and extensive memory bandwidth.
