ADSP-21060LCW-160

Digital Signal Processor Dsp Overview

The ADSP-21060LCW-160 is a 32-bit floating-point digital signal processor from the Analog Devices SHARC family. It operates at a maximum clock frequency of 40 MHz, delivering 120 MFLOPS peak performance and 80 MFLOPS sustained throughput. The device features 4 Mbits of dual-ported on-chip SRAM and utilizes a Super Harvard Architecture with four independent buses for simultaneous instruction fetch and data access. Designed for low-power applications, it functions on a 3.3 V supply voltage. The component is housed in a 240-lead thermally enhanced MQFP package (MQFP_PQ4) and supports IEEE JTAG emulation.

Digital Signal Processor Dsp Feature Summary

• SHARC Core: 40 MIPS execution rate with single-cycle instruction execution and parallel ALU/multiplier operations.
• Memory: 4 Mbits of dual-ported on-chip SRAM organized into two 2 Mbit blocks for independent core and DMA access.
• I/O Interfaces: Includes six link ports, two synchronous serial ports with companding hardware, and a host processor interface.
• DMA Controller: Ten DMA channels enable zero-overhead data transfers between internal memory, external peripherals, and serial/link ports.

Digital Signal Processor Dsp Applications

• High-performance communications systems requiring real-time signal processing.
• Graphics and imaging applications utilizing FFT and filter algorithms.
• Embedded parallel signal processing and instrumentation architectures.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'CW-160' against the manufacturer's current ordering guide to confirm package type and temperature range. Confirm RoHS compliance status as specifications are subject to change without notice. Check for product change notifications regarding lead content or manufacturing site updates before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-throughput floating-point arithmetic with integrated multiprocessing capabilities. Ensure the system design accommodates the 3.3 V I/O voltage levels, distinguishing it from the standard 5 V ADSP-21060 variants. Verify that the 240-lead MQFP footprint fits the PCB layout constraints and thermal management requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2106x SHARC processor family, which includes variants like the ADSP-21060, ADSP-21062, and their low-voltage counterparts. The 'L' designation indicates 3.3 V operation, while the 'C' suffix typically denotes commercial temperature ranges. The ADSP-21060LCW-160 specifically integrates the full 4 Mbit SRAM capacity found in the base ADSP-21060 but optimized for lower power consumption.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package include other ADSP-21060LC variants with different speed grades or temperature ratings, such as ADSP-21060LCB-133 (PBGA package) or ADSP-21060LCW-133. Cross-family migration to newer SHARC processors requires architectural review.
