The GOWIN GW5AT-15 is an Arora V FPGA built around programmable logic and integrated high-speed interfaces, including hard-core MIPI D-PHY and C-PHY and PCIe 3.0 up to x4. GOWIN lists 15,120 LUT4s and 630 kb of block SRAM. Its 4K-video positioning is an application target, not proof of a tested end-to-end 4K pipeline.
What the GW5AT-15 is
The GW5AT-15 belongs to GOWIN Semiconductor’s Arora V transceiver FPGA series. An FPGA combines configurable logic with fixed-function resources; this device adds high-speed serial transceivers and hard MIPI interface blocks alongside its programmable fabric.
GOWIN’s Arora V product page lists these GW5AT-15 resources:
- 15,120 LUT4s and registers
- 630 kb block SRAM across 35 block SRAM units, plus 118.125 kb of shadow SRAM
- 28 DSP blocks and two PLLs
- Four transceivers
- Up to 53 user GPIOs in the listed device configuration
These are manufacturer specifications, not independent measurements.

Which high-speed interfaces it supports
MIPI D-PHY and C-PHY
GOWIN specifies hard-core MIPI D-PHY at up to 2.5 Gbps, with RX and TX, four data lanes, and one clock lane. It specifies MIPI C-PHY at up to 2.5 Gsps, with RX and TX and three trios. Those are the units and limits given on the manufacturer’s product page.
A Hackster.io announcement report separately describes three-lane C-PHY at up to 5.75 Gbps per lane and four-lane D-PHY at up to 2.5 Gbps per lane. Treat the C-PHY figure as the report’s wording: GOWIN’s page gives its figure in Gsps, and the sources do not provide the technical definition needed to equate those units.
Rank #2
- Package Include: 1PCS* 60K Core Board
- 【Advanced Technology】Tang Mega 60K uses the 22nm process GW5AT-LV60P484A FPGA chip with 59904 lookup table units and 118 DSP units. It contains four high-speed transceivers with speeds ranging from 270Mbps to 6.6Gbps, which is suitable for transmitting data on high-speed ports such as PCIe.
- 【Wide Applications】Contains hard-core PCIe and MIPI C/D PHY controllers, which consume better resources and get better performance when using PCIe. It is suitable for high-speed communication, protocol conversion, high-performance computing and other occasions.
PCIe and transceivers
The product page lists PCIe 3.0 at x1, x2, or x4 and four transceivers. GOWIN gives an Arora V GW5AT-series operating range of 270 Mbps to 12.5 Gbps, but that family range is not a promise that every GW5AT-15 package can reach its maximum.
GOWIN says MBGA transceivers can reach 10.3125 Gbps and FCPBGA transceivers can reach 12.5 Gbps. The GW5AT-15 package table lists MG132 MBGA and CS130F WLCSP, not FCPBGA. Exact supported speed depends on device grade and configuration; check the applicable datasheet and package details before designing a link around a target rate.

Packages and I/O
GOWIN’s GW5AT-15 table identifies two packages:
| Package | Pitch |
|---|---|
| MG132 MBGA | 0.5 mm |
| CS130F WLCSP | 0.4 mm |
The same table lists 53 user I/Os, including 25 LVDS pairs. Package selection therefore affects both board-level routing and which high-speed configurations are practical; verify the full pinout and electrical limits in the relevant device documentation.
Does “targets 4K video” mean it has demonstrated 4K performance?
No. Hackster’s headline and report position the GW5AT-15 for 4K-resolution displays and high-speed display and camera interfaces. The available product description and announcement do not establish a particular resolution, frame rate, color depth, or complete video-pipeline demonstration. The 4K claim should be read as an intended application, not as a verified end-to-end performance result.

In a real design, the FPGA’s suitability depends on the entire signal path: the camera or display interface, lane configuration, pixel format and timing, required processing, memory bandwidth, board implementation, and device speed grade. The cited material does not supply a reference design or test result that resolves those system-level questions.
