Gowin Semi introduces Arora V 138K eval board

Apr 21, 2023 — by Giorgio Mendoza 592 views

Gowin Semiconductors announced this week an evaluation board based on the GW5AT-138 FPGA series targeting communications, server imaging, automotive and other high-speed applications.

The GW5AT FPGA (22nm process) belongs to the fifth generation product from the Gowin Arora family. Refer to the GOWINSEMI Arora V FPGA page for more information.


  • GW5AT-LV138FPG676A — 138K LUT4, 298 DSP, 12x PLLs, 2x ADC; 0.9/1.0V core voltage

According to the datasheet, the dev board includes 2x Micron MT41J128M16JT-125:K chips, which are 2Gbit (256MB) DDR3 chips (4Gbit in total) with 32-bits bus width. The storage system interfaces directly with the FPGA as shown above.

The dev board features a GD25Q128 Flash memory chip to retain data after powering down the device. Additionally, there is an industrial-grade PCIe x4 interface for high-speed data communication.
