RT4G150-LGG1657M

The RT4G150-LGG1657M is a member of Microchip's RTG4™ family — a flash-based FPGA architecture designed for high-performance, radiation-tolerant applications. It integrates a dense FPGA fabric with hardened logic, high-speed serial interfaces and memory/memory-controller options for demanding embedded designs.

This device is targeted at systems requiring radiation resistance and extended environmental range. Key on-chip resources include 151,824 logic elements, approximately 5,325 bits of embedded memory, up to 720 user I/O pins, and support for high-speed SerDes and memory interfaces. The device is qualified to military-grade temperature and mechanical requirements and is supplied in a 1657-BCLGA surface-mount package.

Key Features

• Core FPGA Fabric: 151,824 logic elements with 4-input LUT-based logic and fast carry chains; fabric performance cited up to 300 MHz in RTG4 documentation.
• Embedded Memory and DSP: Approximately 5,325 bits of on-chip RAM and embedded multiply-accumulate resources supporting DSP operation up to 300 MHz as described in the RTG4 datasheet.
• High-Speed Interfaces: Native SerDes capability at 3.125 Gbps and on-chip DDR2/DDR3/LPDDR memory controller support for high-bandwidth system interfaces.
• I/O Density: Up to 720 user I/O pins for complex system interconnect and high pin-count designs.
• Radiation Tolerance and Reliability: Flash-based configuration with design-hardened registers to resist radiation-induced single-event upsets (SEUs), suitable for space, high-altitude aviation, medical and nuclear applications as described in the RTG4 family documentation.
• Power and Supply: Core supply voltage range 1.14 V to 1.26 V to match RTG4 recommended operating conditions.
• Package and Mounting: 1657-BCLGA package (supplier package 1657-CLGA, 42.5 × 42.5 mm) in a surface-mount form factor.
• Extended Temperature Range: Military-grade operating range from −55 °C to 125 °C for harsh-environment deployments.

Typical Applications

• Space Systems: FPGA fabric hardened by design and radiation-resistant configuration make the device suitable for Low-Earth Orbit, GEO/HEO and deep-space electronics as referenced in the RTG4 family materials.
• Avionics & High-Altitude Platforms: Extended temperature and radiation tolerance support use in high-altitude aviation and related flight electronics.
• Medical Electronics: Use in medical systems where radiation resilience and reliable, deterministic logic and DSP functions are required.
• Nuclear & Power-Plant Control: Designed-in radiation robustness and military-grade temperature specification support control and monitoring systems in nuclear environments.
• High-Speed Communication Systems: Native 3.125 Gbps SerDes and high I/O count enable high-throughput serial links and memory interface implementations.

Unique Advantages

• Highly integrated FPGA fabric: Large logic element count and embedded DSP/memory resources reduce the need for separate processors or accelerators in complex signal-processing applications.
• Radiation-hardened by design: Registers and configuration memory are designed to resist single-event upsets, reducing mitigation overhead in radiation-prone environments.
• Robust environmental qualification: Military-grade operating temperature and surface-mount 1657-BCLGA packaging support deployment in harsh thermal and mechanical conditions.
• Broad interface support: High I/O density and native high-speed SerDes plus DDR2/DDR3/LPDDR controller support simplify high-bandwidth system design.
• Deterministic DSP capability: Embedded multiply-accumulate blocks and DSP-capable fabric operating to the frequency ranges specified in the RTG4 documentation enable real-time signal processing.
