• Embedded memory — Multiple embedded memory options with 5,325 bits of on-chip RAM for configuration and application data storage.
• DSP and timing — On-chip multiply-accumulate blocks and fabric timing capable of supporting DSP operations up to 300 MHz.
• High-speed serial interfaces — Native SerDes support up to 3.125 Gbps for board‑to‑board and high-speed data links.
• Memory controller support — Integrated DDR2/DDR3/LPDDR memory controller capability for high-bandwidth external memory interfaces.
• Extensive I/O — 720 user I/O pins to support a wide range of peripherals and board-level connectivity.
• Power and supply — Core voltage supply range from 1.14 V to 1.26 V for the device core domain.
• Packaging and mounting — 1657-BCLGA package; supplier device package 1657-CLGA (42.5 × 42.5 mm), surface-mount construction for compact board designs.
• Military-grade operating range — Rated for operation from −55 °C to 125 °C and specified as Grade: Military.
• Radiation-hardened architecture — FPGA fabric hardened by design against radiation-induced single-event upsets (SEUs) for use in harsh radiation environments.

Typical Applications

• Space systems — Flight electronics and payload controllers where radiation tolerance and reliable reconfigurable logic are required.
• High-altitude aviation — Avionics subsystems that need robust logic, high I/O count, and extended temperature operation.
• Medical electronics — Critical instrumentation and imaging control that benefit from FPGA-based flexibility and hardened configuration.
• Nuclear control systems — Control and monitoring applications operating in environments with elevated radiation levels and strict reliability needs.

Unique Advantages

• Radiation-hardened by design — Fabric-level hardening reduces susceptibility to configuration upsets, supporting deployment in radiation-prone environments.
• Substantial programmable capacity — 151,824 logic elements allow implementation of complex control, signal processing, and protocol functions on a single device.
• Integrated high-speed interfaces — 3.125 Gbps SerDes and DDR memory controller support enable high-throughput data paths without extensive external logic.
• Wide thermal tolerance — −55 °C to 125 °C operating range suits systems that experience extreme temperature conditions.
• High I/O availability — 720 I/O pins simplify integration with sensors, transceivers, and external memory, reducing board-level multiplexing or expansion needs.
• Compact, surface-mount package — 1657-BCLGA (42.5 × 42.5 mm) provides a high-density package option for space-constrained PCB layouts.
