• High-Speed SERDES Embedded SERDES capability with data rates up to 3.2 Gbps for serial protocols; family architecture supports multiple high-speed channels for interfaces such as PCI Express, Ethernet and SONET/SDH.
• sysDSP Slices Dedicated DSP resources in the ECP3 family provide high-performance multiply-accumulate operations for signal processing tasks (family-level feature).
• Programmable sysI/O Support for a wide range of I/O standards and pre-engineered source-synchronous interfaces, with DDR registers in I/O cells and dedicated read/write leveling and gearing logic (family-level features).
• Clocking and Timing Device family supports multiple PLLs and DLLs for flexible clock generation and deterministic timing (family-level capability).
• Package & Mounting 672-BBGA package (supplier 672-FPBGA 27 × 27 mm), surface-mount mounting type, and 380 user I/Os for high pin-count board integration.
• Power Core voltage supply range of 1.14 V to 1.26 V for the device core.
• Operating Range & Compliance Industrial temperature grade with operating range from −40 °C to 100 °C; RoHS compliant for environmental standards.
• System-Level Support Family-level features include IEEE 1149.1 and IEEE 1532 support, on-chip oscillator, dual-boot/configuration options and debug/configuration utilities.

Typical Applications

• High‑Speed Communications Implement multi‑protocol serial links (PCIe, Ethernet, SONET/SDH) using embedded SERDES and abundant I/O for line cards and network interfaces.
• Signal Processing & DSP Use dedicated sysDSP slices and embedded memory for real‑time filtering, codec acceleration and multi‑channel signal processing.
• Video & Broadcast Support broadcast standards and high‑bandwidth video transport (SMPTE/3G and similar protocols) with SERDES and large on‑chip buffers.
• Industrial Control & Instrumentation Apply the device’s industrial temperature rating, flexible I/O and deterministic clocking to motor control, sensor aggregation and deterministic control systems.

Unique Advantages

• High logic capacity: 92,000 logic elements enable integration of multiple system functions into a single device, reducing external glue logic and BOM complexity.
• Substantial on‑chip memory: Approximately 4.53 Mbits of embedded RAM for local buffering and state storage, minimizing external memory bandwidth needs.
• High‑speed serial support: Embedded SERDES with up to 3.2 Gbps capability facilitates modern serial protocols and scalable channel counts.
• Flexible I/O and package density: 380 user I/Os in a 672‑ball BGA footprint provide a high pin count for mixed I/O, memory interfaces and peripheral connections.
• Industrial operating range: −40 °C to 100 °C rating supports deployment in industrial environments requiring extended temperature tolerance.
• Comprehensive system features: On‑chip oscillators, boot options, and family support for JTAG and configuration/diagnostic standards simplify development and in‑field updates.
