The range is apparently designed to provide cheap and power-saving performance for a wide range of applications that need lots of I/O at the edge. AMD brags that the Spartan UltraScale+ devices offer the industry's best I/O to logic cell ratio in FPGAs built in 28nm and lower process technology.
AMD claims it delivers up to 30 per cent less power use than the previous generation and has the most robust security features.
AMD Adaptive and Embedded Computing Group boss Kirk Saban said that for more than 25 years, the Spartan FPGA family has helped power some of humanity's finest achievements, from life-saving automated defibrillators to the CERN particle accelerator, which is pushing the limits of human knowledge.
"Building on proven 16nm technology, the Spartan UltraScale+ family's improved security and features, common design tools, and long product lifecycles further boost our market-leading FPGA range and show our commitment to delivering cost-optimized products for customers."
AMD said that the family offers the industry's best I/O to logic cell ratio of FPGAs built on 28nm and below process technology. It has up to 572 I/Os and voltage support up to 3.3V, making any-to-any connectivity possible for edge sensing and control applications.
The 16nm fabric and support for a wide range of packaging, starting as tiny as 10x10mm, give high I/O density in a small footprint. The huge AMD FPGA range also provides scalability with cost-optimized FPGAs and goes up to midrange and high-end products.
Through 16 nm FinFET technology and hardened connectivity, the Spartan UltraScale+ family is expected to offer up to a 30 per cent power cut compared to the 28nm Artix 7 family.
They are the first AMD UltraScale+ FPGAs with a hardened LPDDR5 memory controller and PCIe Gen4 x8 support, giving customers power efficiency and future-ready features.
AMD said the range supports post-quantum cryptography with NIST-approved algorithms and offers state-of-the-art IP protection against changing cyber-attacks and threats. A physical, unclonable function gives each device a unique fingerprint for extra security.
It offers PPK/SPK key support to help manage old or hacked security keys, while differential power analysis helps protect against side-channel attacks. The devices have a permanent tamper penalty to further protect against misuse.
The AMD range of FPGAs and adaptive SoCs are supported by the AMD Vivado Design Suite and Vitis Unified Software Platform, letting hardware and software designers use the benefits of these tools and included IPs via a single designer cockpit from design to verification.
AMD Spartan UltraScale+ FPGA family samples and evaluation kits are expected to be available in the first half of 2025.
