• I/O and Packaging — 349 I/O signals in a 484‑ball FCCSP package (484‑FCCSP, 19×19 mm) for high-density board integration and flexible external interfacing.
• Power — Device core supply specified at 820 mV.
• Commercial Temperature Grade — Operating range from 0 °C to 85 °C, suitable for commercial applications.
• Clocking and Timing — On‑chip oscillator, PLLs, and a multi-layer clocking structure including global, regional and edge clocks plus dynamic clock control options as outlined in the platform overview.
• Memory and DSP Subsystems — Dedicated sysMEM and sysDSP blocks provide memory and signal‑processing resources for embedded buffering and arithmetic workloads.
• Programmable I/O and PHY — Programmable I/O cell (PIC) architecture, sysI/O banking, DDRPHY overview and SERDES/PCS blocks enable configurable I/O standards and high‑speed interface support described in the Avant documentation.
• Configuration and Diagnostics — Enhanced configuration options, JTAG support, and SEU handling mechanisms are included in the Avant platform specification.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• High‑capacity Logic Implementations — Use the large logic element count for complex control, protocol handling, or custom processing blocks in commercial embedded systems.
• On‑chip Memory‑intensive Designs — Leverage approximately 4.24 Mbits of embedded RAM for buffering, lookup tables, and intermediate data storage without external memory in some designs.
• Flexible I/O and Interface Control — 349 I/Os and programmable I/O cells support diverse interface needs including memory interfaces, peripheral control, and multi‑protocol PHY integration.
• DSP and Accelerator Functions — sysDSP and sysMEM resources enable implementation of arithmetic pipelines, filters, and embedded data‑path accelerators within the FPGA fabric.

Unique Advantages

• High Logic Density: 637,000 logic element cells enable integration of large, complex designs on a single device, reducing the need for multiple FPGAs.
• Multi‑Megabit Embedded Memory: Approximately 4.24 Mbits of on‑chip RAM with FIFO, cascading, and multi‑port modes simplifies buffering and memory architecture.
• Rich Clocking Architecture: On‑chip oscillator, PLLs and configurable clock domains provide flexible timing strategies for mixed‑frequency designs.
• Flexible I/O and PHY Support: 349 I/Os combined with programmable I/O cell architecture and DDR/serdes building blocks support diverse external interfaces.
• Compact, High‑density Package: 484‑FCCSP (19×19) package supports dense board layouts where area and I/O count are priorities.
• Commercial Grade Reliability: Specified for 0 °C to 85 °C operation and RoHS compliant for standard commercial deployments.
