• High-Density I/O — 298 user I/O pins with the Avant programmable I/O cell (PIC) architecture and sysI/O banking scheme for flexible signaling and register options.
• Clocking and Timing — On-chip oscillator, PLLs, global and regional clock networks, dynamic clock select/control, DLL delay and clock synchronizers referenced in the platform architecture to support complex timing domains.
• High-Speed Interface Support — Platform-level support for DDR memory interfaces (DDRPHY) and SERDES/PMA and multi-protocol PCS/MPPHY integration as described in the Avant datasheet.
• Package and Mounting — Available in a 676-BBGA / 676-FCBGA (27×27) package suitable for surface-mount assembly.
• Industrial Temperature and Supply — Rated for operation from −40 °C to 100 °C; voltage supply specified at 820 mV.
• Configuration and Reliability — Platform-level features include enhanced configuration options, JTAG support, and SEU handling mechanisms as described in the Avant platform overview.
• Compliance — RoHS-compliant device.

Typical Applications

• Industrial Control — Programmable logic and industrial temperature rating support custom motor control, automation I/O aggregation, and protocol bridging in harsh environments.
• High-Bandwidth Memory Interfaces — DDRPHY support and embedded sysMEM capabilities enable designs requiring local buffering and high-throughput memory access.
• Protocol and Interface Bridging — Programmable I/O cells and SERDES/PCS building blocks facilitate implementation of custom interface logic and multi-protocol PHY integration.
• Signal Processing and Acceleration — The combination of a large logic element count and sysDSP/sysMEM resources is suited to on-device acceleration and real-time processing tasks.

Unique Advantages
