ADSP-21065LCCAZ240

Digital Signal Processor Dsp Overview

The ADSP-21065LCCAZ240 is a 32-bit floating-point digital signal processor from the SHARC family, manufactured by Analog Devices Inc. It operates at a maximum clock frequency of 66 MHz, delivering 66 MIPS and 198 MFLOPS peak performance. The device features 544 Kbits of configurable on-chip SRAM organized into two dual-ported blocks. Key interfaces include a host port, an external port with SDRAM controller support, and four serial ports (SPORTs) capable of I2S and TDM modes. It utilizes a Super Harvard Architecture with four independent buses for single-cycle instruction and data fetches. The component is housed in a 196-ball Mini-BGA package and supports 3.3V operation.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance if required by your manufacturing standards. Confirm the 'C' package code corresponds to the 196-ball Mini-BGA form factor. Check current product status as older SHARC models may have end-of-life implications. Ensure development tools like VisualDSP++ are compatible with the target revision.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance floating-point math is required alongside integrated memory and I/O peripherals. The 196-ball BGA package suits space-constrained designs requiring dense pin counts. Consider the 66 MHz speed limit; higher-frequency variants like the ADSP-21065LKCA-264 (66 MHz but different package/performance metrics) or newer SHARC cores may be needed for stricter timing budgets.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-2106x family, which is code-compatible with earlier ADSP-21060/21061/21062 processors. It represents a cost-sensitive optimization within the SHARC line, offering full IEEE floating-point precision without sacrificing the single-cycle execution capabilities of the architecture. It serves as a bridge between legacy 5V SHARC designs and modern 3.3V systems.

Digital Signal Processor Dsp Replacement Considerations

For direct architectural replacements, consider the ADSP-21065LKCA-264 for similar functionality in a BGA package. For migration to newer SHARC generations, the ADSP-21375 offers enhanced performance and power efficiency while maintaining software compatibility.
