LX7720MLF Evaluation Board User Guide

Description

The LX7720MLF evaluation board (EVB) contains a soldered in place LX7720MLF and peripherals to allow LX7720

functionality to be quickly evaluated. Demonstration firmware is available for RTG4 FPGAs and SAM rad hard MCUs.

The LX7720MLF EVB uses a 40-way header for connection to FPGA or MCU controllers. The kit includes linker boards

for direct plug-in connection to an RTG4 FPGA FPGA DEV-KIT, an RT PolarFire FPGA RTPF-DEV-KIT, a PolarFire

MPF300-EVAL-KIT, a SmartFusion2SoC FPGA M2S150-ADV-DEV-KIT, a SAMRH71F20 MCU Evaluation Kit and

SAMRH71-TFBGA-EK Evaluation Kit, and a SAMRH707F18 MCU Evaluation Kit.
