ADSP-21060LKSZ-160

Digital Signal Processor Dsp Overview

The ADSP-21060LKSZ-160 is a 32-bit SHARC floating-point digital signal processor from Analog Devices, operating at a clock rate of 40 MHz. It features a Super Harvard Architecture with four independent buses for dual data fetch and instruction fetch. The device includes 512 kB (4 Mbit) of dual-ported on-chip SRAM and integrated I/O peripherals, forming a complete system-on-a-chip. Key computational units include a 32-bit IEEE floating-point multiplier, ALU, and shifter capable of single-cycle execution. It supports multiprocessing via link ports and a host interface.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'LKSZ-160' against the manufacturer's current ordering guide to confirm package type (240-lead MQFP_PQ4), voltage (3.3 V), and temperature range. Confirm RoHS compliance status as specifications are subject to change without notice. Check for any product change notifications or end-of-life statuses prior to procurement.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-speed floating-point DSP performance with integrated memory and I/O. Ensure the design supports 3.3 V operation, as indicated by the 'L' suffix in the part number. Verify that the 240-lead MQFP package fits the PCB layout constraints. Consider the need for external memory if the internal 512 kB SRAM is insufficient for the application's code and data storage requirements.

Digital Signal Processor Dsp Part Context

The ADSP-21060LKSZ-160 belongs to the ADSP-2106x SHARC family, which builds upon the ADSP-21000 DSP core. This family offers high levels of DSP performance through a complete system-on-a-chip design. The 'L' variant specifically denotes 3.3 V operation, distinguishing it from the 5 V ADSP-21060 variants. The 'KSZ' suffix typically indicates the package type and thermal enhancement features.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include other ADSP-21060 variants with different voltages or packages, such as ADSP-21060KS-160 (5 V) or ADSP-21060CZ-160 (5 V CQFP). For 3.3 V alternatives, consider ADSP-21060LCW-160 or ADSP-21060KBZ-160, ensuring pin compatibility and voltage level matching.
