M-Series Agilex Featuring DDR5

The Intel Agilex M-Series FPGAs are optimized for applications that are throughput- and memory-intensive.

  • 64GBytes DDR5: A hardened memory NoC supports the two large banks of DDR5 on the IA-865m.
  • 400G: Configurable networking support for the most demanding bandwidth requirements.
  • PCIe Gen5 and CXL Support: Data transfer speeds 2x faster than Gen4, and high-speed interface between CPUs and workload accelerators.

400G Networking

IA-865m provides up to 3x 400G to support the most demanding bandwidth requirements. Configurable networking support includes hard Ethernet media access control (MAC), physical coding sublayer (PCS), and forward error correction (FEC) for a range of speeds.

DDR5 Memory Support

 Intel® Agilex™ M-Series FPGAs—with  support for DDR5—feature a new hardened memory network-on-chip (NoC) to enhance transport layers with more performance, improved efficiency, and fewer FPGA resources required. 

PCIe Gen5 and CXL

PCIe Gen5 supports data transfer speeds 2x higher than PCIe Gen4, providing greater performance capabilities to developers of PC interconnect, graphics adapters, and chip-level communications. And Compute Express Link (CXL) support enables high-speed, low-latency interface to CPUs.

Generation 5.0

Double the Bandwidth!

Built with the latest PCIe Gen5 interface, the IA-860m can transfer up to twice the bandwidth of Gen4 devices.

Enterprise-class for Deployment

Ramp to product with the power of Molex

The IA-865m is built on BittWare’s enterprise-class foundation stones: existing products and processes that are already proven through extensive validation. When it’s time to ramp to production, this means a faster turnaround and utilizing the same hardware you have been using for development.

Flexible Expansion IO

With QSFP-DDs and MCIO connectors, the IA-865m offers a range of flexibility to meet your application needs:

  • Three QSFP-DDs provide up to 3x 400G (12x 100G, or 24x 10/25/50G).
  • MCIO expansion port lets you optimize the IA-865m for your application with PCIe expansion.

Inquire about customized Molex connectors/cables as required for your application.

Supporting CXL

CXL (Compute Express Link) is an industry-supported cache-coherent interconnect between processors, memory expansion, and accelerators. CXL technology maintains memory coherency between the CPU memory space and memory on attached devices, which allows resource sharing with lower latency, reduced software stack complexity, and lower overall system cost. 

* CXL requires licensing that is sold separately from the card
