Intel Arria® V FPGA GZ FPGA PCIe Board with Dual SFP+ and DDR3, QDRII+, or RLDRAM3

The A5-PCIe-S (A5PS) from BittWare is a low-profile PCIe x8 card based on the Intel Arria V GZ FPGA.


The high-performance, power- and cost-efficient Arria V GZ FPGA provides a high level of system integration and flexibility for I/O, routing, and processing. Up to 8 GBytes of on-board memory includes DDR3, QDRII/II+, or RLDRAM3. Two front-panel SFP+ cages allow two 10GigE interfaces.

The A5PS provides a variety of interfaces for high-speed serial I/O as well as debug support. Two SFP+ cages are available on the front panel, each supporting a 10GigE channel using optical transceivers as well as passive copper cabling up to 8 metres.

The Gen3 x8 PCIe interface provides 8 SerDes lanes to the Arria V GZ FPGA. A USB 2.0 interface and an optional JTAG connector are available for debug and programming support. The A5PS also features a Board Management Controller (BMC) for advanced system monitoring, which greatly simplifies platform management.

The A5PS features an extremely flexible memory configuration, with a SODIMM site that supports DDR3 SDRAM, RLDRAM3, and QDRII+. Memory card options include the following: up to 8 GBytes of DDR3 with optional error-correcting codes (ECC); up to 36 MBytes QDRII+ (2 banks x18); or up to 512 MBytes RLDRAM3 (2 banks x18). Additional on-board memory includes flash memory for storing multiple FPGA images. An on-board PROM provides access to the board’s MAC ID.
