• Generous I/O — Up to 720 user I/O pins to connect dense peripheral, sensor, or data-path interfaces.
• Robust electrical and thermal envelope — Supply voltage range of 1.14 V to 1.26 V and operating temperature range from –55 °C to 125 °C; surface-mount package.
• Package — 1657-BFCCGA (supplier package 1657-CCGA, 42.5 × 42.5 mm) for high-pin-count, board-level integration.
• Regulatory status — RoHS compliant and listed as a production device in the RTG4 device status.

Typical Applications

• Spaceflight and satellite systems — Radiation-resistant FPGA fabric and hardened registers make the device suitable for on-board processing and control in LEO, MEO, GEO, HEO and deep-space missions.
• High-altitude aviation — Military-grade temperature range and SEU-resistant configuration are suitable for avionics and high-altitude sensor processing.
• Medical electronics — Deterministic DSP blocks and high I/O density support real-time signal processing in medical instrumentation.
• Nuclear and industrial control — Radiation-tolerant architecture and robust thermal range address control systems operating in high-radiation or harsh environments.
• High-speed communication endpoints — Built-in SerDes and memory controller support for high-speed serial links and external memory interfaces.

Unique Advantages

• Radiation-hardened by design — Architecture and hardened registers reduce the risk of radiation-induced configuration upsets in hostile environments.
• Large, deterministic logic fabric — 151,824 logic elements enable complex control, signal processing and protocol implementations on a single device.
• Integrated high-speed interfaces — Native 3.125 Gbps SerDes plus DDR2/DDR3/LPDDR memory controller options minimize external component count and simplify board design.
• Wide operating range — Military-grade temperature rating (–55 °C to 125 °C) and a narrow, defined supply range (1.14 V to 1.26 V) for predictable behavior in demanding deployments.
• High I/O density — Up to 720 I/Os for flexible system partitioning and rich peripheral connectivity.
• Production-ready device — RTG4 RT4G150 family devices are listed as production devices in the datasheet device status.
