• DSP Resources — Dedicated multiplier resources (128 × 18×18 multipliers for the ECP3-70 device) for filtering, signal processing and acceleration of arithmetic-heavy algorithms.
• High‑Speed SERDES — Embedded SERDES supporting data rates up to 3.2 Gbps per channel and multiple SERDES channels in the 672‑package for serial interfaces and high-speed links.
• Rich I/O — 380 user I/Os with programmable sysI/O supporting a wide range of standards (LVTTL, LVCMOS, SSTL, HSTL, LVDS and others) for flexible interfacing to memory, transceivers and peripherals.
• Clocking and Timing — Up to ten PLLs and two DLLs enable complex clocking schemes, clock management and on-chip frequency synthesis for multi-rate systems.
• Configuration & System Support — Flexible configuration options including SPI boot, dual-boot images, TransFR I/O and Soft Error Detect; system-level support includes IEEE 1149.1 and IEEE 1532 compatibility, Reveal Logic Analyzer and ORCAstra configuration utilities.
• Power and Operating Range — Core voltage supply range of 1.14 V to 1.26 V and commercial operating temperature range of 0 °C to 85 °C.
• Package & Mounting — 672‑ball BGA package (672‑FPBGA, 27 × 27 mm) in a surface-mount form factor; RoHS compliant.

Typical Applications

• Networking & Communications — Implement protocol bridges, packet processing and line-side interfaces leveraging SERDES channels and abundant I/O for Ethernet, PCIe and serial protocols.
• Video & Broadcast — Frame buffering, timing and format conversion for SMPTE and high-speed video links using embedded memory and DSP resources.
• High‑Speed Data Acquisition — Front-end aggregation and real-time preprocessing for ADC/DAC interfaces using DSP slices, dedicated I/O features and on-chip memory.
• Embedded Compute & Acceleration — Offload compute-intensive kernels and custom accelerators to the FPGA fabric and sysDSP resources for latency-sensitive applications.

Unique Advantages

• High integration density: 67,000 logic elements and substantial embedded memory reduce external components and simplify board-level design.
