ADSP-21061KSZ-160

Digital Signal Processor Dsp Overview

The ADSP-21061KSZ-160 is a commercial-grade SHARC DSP microcomputer from Analog Devices, operating at a 40 MHz clock rate. It features a 32-bit IEEE floating-point architecture with 120 MFLOPS peak performance and 50 MIPS throughput. The device integrates 1 Mbit of dual-ported on-chip SRAM, an instruction cache, and dedicated I/O peripherals including two serial ports and a host interface. Packaged in a 240-lead MQFP with a thermal slug, it supports single-cycle execution via Super Harvard Architecture.

Digital Signal Processor Dsp Feature Summary

• Super Harvard Architecture enabling simultaneous fetch of one instruction and two operands
• Integrated 1 Mbit dual-ported SRAM organized into two 0.5 Mbit blocks
• Dual synchronous serial ports supporting up to 50 Mbps data rates
• Hardware circular buffers via two Data Address Generators (DAGs)

Digital Signal Processor Dsp Applications

• High-performance communications signal processing
• Real-time graphics rendering and imaging applications
• Multiprocessor DSP systems requiring glueless interconnection

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '160' corresponds to the 40 MHz operational frequency required for the design. Confirm that the 240-lead MQFP package with thermal enhancement matches the PCB footprint and thermal management capabilities of the target system.

Digital Signal Processor Dsp Selection Notes

Select this component when a complete system-on-a-chip solution is needed, eliminating external memory requirements due to the integrated 1 Mbit SRAM. Ensure compatibility with existing ADSP-21000 family codebases, as the device maintains object code compatibility with predecessors like the ADSP-21060.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-21061/ADSP-21061L SHARC family. The 'K' indicates the 240-lead MQFP package, while 'S' denotes lead-free construction. The '160' suffix specifies the 40 MHz speed grade, distinct from the 50 MHz '176' or 33 MHz variants.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21061KS-160 is a direct pin-compatible predecessor. For higher performance, the ADSP-21061KSZ-176 offers a 50 MHz clock rate within the same package.
