Taiwan's Terasic Technologies, into FPGA kit design and turnkey solutions and the exclusive board manufacturer for Altera Corporation, has launched its new TR4 high-density Altera Stratix IV FPGA platform in two flavors - Altera’s Stratix IV GX with 230K or 530K logic elements.

The TR4 has a high number of available I/O pins, high speed, and low-power and features a stacking mechanism that enables engineers to choose the number of logic elements required for the end design.

The TR4 enables stacking through multiple High Speed Mezzanine Card (HSMC) connector ports featuring back-side male connectors for connecting to other TR4 boards. In total, there are 492 free I/O pins as well as transceivers that support a data rate up to 8.5 Gbps. The number of ports allows engineers to match the TR4 board to exact specifications by using add-on cards from Terasic or custom solutions.

The TR4 includes two Gen.2 x4 PCIe connectors that allow high-speed communication with a host computer. For memory, a DDR3 SO-DIMM module is provided, as well as on-board flash memory and high-speed SSRAM. The TR4 also features an on-board USB Blaster for direct FPGA programming via USB.
