ADSP-21062KS-160

Digital Signal Processor Dsp Overview

The ADSP-21062KS-160 is a 32-bit floating-point digital signal processor from the SHARC family, manufactured by Analog Devices Inc. It operates at a clock rate of 40 MHz with a 25 ns instruction cycle time. The device features 2 Mbit (256 kB) of on-chip dual-ported SRAM and supports IEEE single-precision and extended-precision floating-point formats. Key electrical parameters include a 5.00 V core and I/O voltage supply. It utilizes a 240-lead MQFP_EP package with exposed pads for thermal enhancement.

Digital Signal Processor Dsp Feature Summary

• Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch and dual data access in a single cycle.
• Integrated multiprocessing capabilities including six link ports and distributed bus arbitration for glueless connection of up to six processors.
• On-chip DMA controller with ten channels supporting background transfers at up to 40 MHz without processor intervention.
• Dual data address generators (DAGs) implementing hardware circular buffers for efficient delay line and filter processing.

Digital Signal Processor Dsp Applications

• Real-time complex background image processing and target tracking systems.
• Communications applications requiring high-performance signal processing.
• Graphics and imaging applications utilizing parallel computation units.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as packages are specified as compliant. Check for lead-bearing deviations via Product Change Notifications if sourcing from secondary markets. Ensure proper handling for moisture sensitivity level 3 components.

Digital Signal Processor Dsp Selection Notes

Select this model when 2 Mbit of on-chip memory is sufficient, distinguishing it from the 4 Mbit ADSP-21060 variants. Choose the KS suffix for the 240-lead MQFP_EP package suitable for surface mount assembly. Verify 5.00 V power supply requirements against system constraints, as the L-series variants operate at 3.3 V.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2106x SHARC processor family, which includes the ADSP-21060, ADSP-21060L, ADSP-21062, ADSP-21062L, ADSP-21060C, and ADSP-21060LC. The ADSP-21062 variant specifically provides 2 Mbit of SRAM, whereas the ADSP-21060 provides 4 Mbit. All share the same core architecture and instruction set compatibility.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21060KS-160 serves as a functional substitute with identical pinout and performance but offers 4 Mbit of on-chip SRAM instead of 2 Mbit. Ensure software memory allocation is adjusted to accommodate the larger memory space if used as a drop-in replacement.
