Efinix Titanium Ti375 FPGA offers quad-core hardened RISC-V block, PCIe Gen 4, 10GbE

Efinix Titanium Ti375 SoC combines high-density, low-power Quantum compute fabric with a quad-core hardened 32-bit RISC-V block and features a LPDDR4 DRAM controller, a MIPI D-PHY for displays or cameras, and 16 Gbps transceivers enabling PCIe Gen 4 and 10GbE interfaces.

The Titanium Ti375 also comes with 370K logic elements, 1.344 DSP blocks, 2,688 10-Kbit SRAM blocks, and 27,53 Mbits embedded memory, as well as DSP blocks optimized for computing and AI workloads, and XLR (eXchangeable Logic and Routing) cells for logic and routing.

Manufacturing Process – TSMC 16nm

Right now, eight 529-ball FBGA SKUs are available with different temperature ranges (commercial vs industrial) and speed grades. I could not find any information about the 1,156-ball FBGA devices, so I’d assume they may be coming later on.

The Ti375 is the most powerful Titanium FPGA from Efinix so far, although the Ti550, Ti750, and Ti1000 FPGAs are in the pipeline with up to around one million logic elements and the introduction of 25.8 Gbps transceivers.

All Efinix FPGAs, including the new Titanium Ti375, are supported by the Efinity software (RTL-to-bitstream compiler) available for Windows 10/11 64-bit and Linux (Ubuntu/Red Hat Enterprise). The RISC-V block in the FPGA is based on the company’s Sapphire soft-core that can run bare metal code, RTOS, or Linux. Efinix provides BR2-Efinix custom Buildroot external tree for building Linux with OpenSBI, U-boot, Linux, and Buildroot configuration files as well as patches. You’ll find the code and instructions to get started on GitHub.

There’s no public information about an evaluation board for the Titanium Ti375 at this time. Potential applications include PCIe cards, RF repeaters and radio units, small cell/massive MIMO, cable modems, machine vision, automotive, AV equipment and broadcast, medical imaging, and video bridges.

I could not find pricing and availability information, but Efinix commits to supporting the Titanium family of FPGAs in customer designs until at least 2037. Additional information may be found on the product page.
