XCZU42DR-L1FFVE1156I

Soc System On Chip Overview

The XCZU42DR-L1FFVE1156I is an AMD Zynq UltraScale+ RFSoC device built on a 16nm FinFET process. It integrates a Processing System (PS) with quad-core ARM Cortex-A53 and dual-core ARM Cortex-R5 processors, alongside Programmable Logic (PL) containing approximately 700K logic cells. The chip features eight 14-bit RF-ADCs and eight 14-bit RF-DACs, supporting direct RF sampling up to 6 GHz. The -L1 suffix indicates a low-speed grade, while the 'I' suffix denotes industrial temperature operation from -40°C to +100°C.

Soc System On Chip Feature Summary

• Integrated 8-channel 14-bit RF-ADCs and 8-channel 14-bit RF-DACs for direct RF sampling
• Heterogeneous architecture combining ARM Cortex-A53/R5 processing cores with FPGA fabric
• ~700K system logic cells with extensive DSP slices for signal processing
• Industrial temperature rating (-40°C to +100°C) for robust environmental operation

Soc System On Chip Applications

• Software-defined radio (SDR) systems
• Electronic warfare and signal intelligence platforms
• Test and measurement instrumentation
• Satellite communication ground stations

Soc System On Chip Procurement Notes

Verify the specific speed grade '-L1' against design timing requirements, as it represents a lower performance tier compared to standard grades. Confirm the package type is 1156-pin FCBGA (35x35 mm). Ensure the industrial temperature range aligns with the target deployment environment. Request official datasheets to validate pinout compatibility and power specifications before integration.

Soc System On Chip Selection Notes

Select this model when high channel count RF conversion is required but maximum switching speeds are not critical. Compare resource utilization against the XCZU47DR series if higher logic density or faster ADC/DAC rates are needed. Evaluate thermal management solutions suitable for the 1156-FCBGA package. Consider the trade-off between the lower speed grade and potential cost or availability benefits.

Soc System On Chip Part Context

This component belongs to the Zynq UltraScale+ RFSoC family, designed to merge RF front-end capabilities with programmable logic. It serves as a successor to traditional multi-chip RF architectures by integrating converters directly onto the silicon die. The XCZU42DR variant offers a balance of RF channels and logic resources, targeting mid-range high-performance applications within the broader RFSoC portfolio.

Soc System On Chip Replacement Considerations

Direct functional replacements within the same package and pinout include other XCZU42DR variants with different speed grades (e.g., XCZU42DR-1FFVE1156I). For upgraded performance, consider the XCZU47DR series, which provides increased logic resources and higher converter speeds. Verify pin-to-pin compatibility and firmware compatibility when migrating between speed grades.
