MYiR Tech launches AMD XC7A100T Artix-7 FPGA system-on-module and development board with PCIe, SFP+ cages, dual GbE

MYIR MYC-J7A100T is a System-On-Module (SoM) powered by an AMD/Xilinx Artix-7 XC7A100T FPGA with up to 101,440 logic cells, 512MB DDR3 memory, 32MB QSPI FLASH, 32KB EEPROM, DC-DC power management, and other integral circuits in a compact 69.6 x 40mm form factor.

The module exposes up to 178 FPGA I/Os, four pairs of GTP high-speed transceiver interfaces, and a JTAG interface through its 260-pin edge connector. MYiR also provides a development board for the MYC-J7A100T module which looks like a PCIe 2.0 card and comes with SFP+ cages, HDMI input and output ports, dual GbE, and a GPIO expansion header.

Software, price, and availability

MYiR Tech provides a range of Vivado sample codes for testing purposes from a basic LED blinky to more complex HDMI input/output, PCIe, and SFP+ test programs. The company will not typically make those public and only provides software resources to paying customers.

It’s unclear why MYiR decided to launch Artix-7 FPGA at this time as the Xilinx (now AMD) XC7A100T FPGA has been around for many years, and we previously covered Trenz Electronic TE0725LP board in 2019 and the MicroNova Mercury 2 in 2020. We also wrote about a 3D game engine C to FPGA implementation running on Digilent Arty A7-100T board with the same XC7A100T FPGA.

The solution is said to be suitable for industrial control, automation, communication, computing, and other highly customized applications. MYIR MYC-J7A100T system-on-module and  MYD-J7A100T AMD XC7A100T FPGA development board are available now for $125 and $169 respectively. More details, including hardware documentation and purchase links, can be found on the product page.

  1. Despite the picture saying SFP+, this FPGA can only reach SFP (non-plus) speeds on the GTP transceivers (SFP+ is 10G, SFP is 1G)
