XCZU47DR-L1FSVE1156I

Soc System On Chip Overview

The XCZU47DR-L1FSVE1156I is a Zynq UltraScale+ RFSoC System on Chip manufactured by AMD. It integrates a Processing System (PS) with quad-core ARM Cortex-A53 and dual-core ARM Cortex-R5 processors, alongside Programmable Logic (PL) featuring approximately 930K logic cells and extensive DSP resources. The device includes eight 14-bit RF-ADCs and eight 14-bit RF-DACs, supporting direct RF sampling up to 6 GHz. The -L1 suffix indicates a lower speed grade compared to the standard -2 variant, while the FFVE1156 package provides 1156 pins in a 35x35 mm FCBGA form factor suitable for high-density applications.

Soc System On Chip Part Context

This component belongs to the Zynq UltraScale+ RFSoC family, specifically the 47DR series which denotes the density of programmable logic and RF converter resources. The 'L1' speed bin represents a lower frequency capability than the '-2' industrial grade variants, offering flexibility for designs where maximum clock speeds are not required but cost or power efficiency is prioritized. It shares the same physical footprint as other FFVE1156 devices in the series.

Soc System On Chip Replacement Considerations

Direct pin-compatible replacements include other members of the XCZU47DR family such as the XCZU47DR-2FFVE1156I, though the -2 variant offers higher speed grades. Designers must verify that the reduced timing margins of the -L1 grade meet their system's clocking requirements when substituting with faster bins.
