ADSP-21060LKS-160

Digital Signal Processor Dsp Overview

The ADSP-21060LKS-160 is a 32-bit floating-point digital signal processor from the Analog Devices SHARC family, operating at a maximum clock frequency of 40 MHz. It features a Super Harvard architecture with four independent buses for simultaneous instruction fetch and dual data access. The device integrates 512 kB of on-chip SRAM organized into two dual-ported blocks, supporting single-cycle execution via an instruction cache. Key peripherals include a DMA controller with ten channels, six link ports, two synchronous serial ports, and a host processor interface. It operates on a 3.3 V supply and is housed in a 240-lead MQFP package.

Digital Signal Processor Dsp Feature Summary

• SHARC Core: 40 MIPS performance with 120 MFLOPS peak throughput using parallel ALU, multiplier, and shifter units.
• Memory Architecture: 512 kB dual-ported on-chip SRAM with separate program and data buses for unconstrained data flow.
• I/O Interfaces: Includes six link ports, two 40 Mbps serial ports, and a host interface for direct memory access by external processors.
• DMA Controller: Ten dedicated channels enable zero-overhead data transfers between internal/external memory and peripherals.

Digital Signal Processor Dsp Applications

• Communications systems requiring high-performance signal processing
• Graphics and imaging applications utilizing FFT and filter algorithms
• Multiprocessor DSP architectures with glueless interconnection

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as manufacturing processes may evolve. Check for lead-free packaging specifications if required by assembly standards. Ensure ESD precautions are followed during handling due to moisture sensitivity level 3 classification.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 3.3 V operation and 40 MHz processing speed. Choose the LKS suffix variant specifically for the 240-lead MQFP package with exposed pad. Compare against ADSP-21060 (5 V) or ADSP-21062 (2 Mbit SRAM) variants if voltage or memory requirements differ. Ensure thermal management supports the power dissipation characteristics of the MQFP package.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2106x SHARC family, which includes variants like the ADSP-21060, ADSP-21062, and their low-voltage counterparts. The 'L' indicates 3.3 V operation, 'K' denotes the MQFP package, and 'S' typically signifies a specific temperature grade or revision within the series. It shares architectural compatibility with other SHARC processors while offering distinct memory and voltage configurations.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package and voltage domain should be evaluated. Consider the ADSP-21060LC series for similar functionality in CQFP packages. Verify that any substitute maintains the 40 MHz clock speed and 512 kB SRAM capacity to ensure software compatibility.
