Acromag XMC-7A5x-AP323

The FPGA can be programmed with Xilinx Vivado® design tools, and the company provides software development tools for VxWorks, Linux, and Windows environments, as well as an example FPGA program described as follows:

IP integrator block diagram provided for PCIe bus 1 lane Gen 1 interface, DMA controller, on chip block RAM, flash memory and control of field I/O.

It is part of an Engineering Design Kit (EDK) software that provides users with the basic information required to develop a custom FPGA program and must be ordered with the first purchase of a XMC-7A50-AP323 series module. Besides the VHDL example, the EDK also includes schematics, parts list, part location drawings, and other utility files.

Acromag XMC-7A50-AP323 module starts at $2,750, with the recommended EDK software adding $360. Further information may be found on the product page and announcement.
