Microsemi™ (Actel) Prototyping ALDEC has developed a prototyping solution for RTAX-S/SL and RTSX-SU devices using reprogrammable flash-based ProASIC3E FPGA's (both the RTAX/RTSX and ProASIC3E device families belong to Actel). The RTAX-S/SL and RTSX-SU prototyping package includes a prototyping adaptor board that maps the footprint of the ProASIC3E device to the footprint of the RTAX-S/SL and RTSX-SU device (e.g. CQ208, CQ256, CQ352, CG624). Support is also available for the larger CG1272 packages, call for details. After soldering the adaptor to the PCB, the ProASC3E device can be reprogrammed through the JTAG interface connector.
