RT4G150-1LGG1657B

The RT4G150-1LGG1657B is a Microchip Technology RTG4™ field programmable gate array (FPGA) designed for high-reliability, mission-critical systems. It integrates a flash-based FPGA fabric with hardened logic elements and high-performance interfaces for applications that require resistance to radiation-induced configuration upsets and extended temperature operation.

This device targets space, high-altitude aviation, medical electronics and nuclear control environments where reliability, deterministic logic performance and robust I/O are required. The architecture combines a large logic element count, embedded memory and DSP capabilities with high-speed serial interfaces and DDR memory controller support.

Key Features

• Core Logic — 151,824 logic elements (registers/logic cells) with 4-input LUTs and fast carry chains for synchronous logic implementations and predictable timing.
• Embedded Memory & DSP — Multiple embedded memory resources (total RAM: 5,325 bits reported) and embedded multiply-accumulate blocks for DSP workloads operating up to 300 MHz.
• High‑Speed Serial Interfaces — Native SerDes communication at 3.125 Gbps and support for DDR2/DDR3/LPDDR memory controllers for high-bandwidth data transport.
• Radiation‑Hardened by Design — Fabric and registers are hardened against radiation-induced single-event upsets (SEUs) and designed to resist configuration upsets in harsh radiation environments.
• I/O Density — 720 user I/O pins to support complex system interfaces and wide peripheral connectivity.
• Package & Mounting — 1657-BCLGA package (supplier device package 1657-CLGA, 42.5×42.5 mm) with surface-mount mounting for high-density board designs.
• Power Supply — Core voltage supply range from 1.14 V to 1.26 V for core power planning and regulation.
• Wide Operating Temperature — Rated for −55 °C to 125 °C and specified as Military grade for harsh-environment deployments.
• Standards & Design Resources — Datasheet and technical briefs provide detailed specifications for I/O standards, SerDes, clock conditioning and system controller interfaces.
• RoHS Compliant — Device meets RoHS compliance requirements for lead-free manufacturing and assembly.

Typical Applications

• Space Systems — Radiation‑hardened architecture and extended temperature range make it suitable for LEO, MEO, GEO, HEO and deep-space missions where configuration integrity is critical.
• High‑Altitude Aviation — Use in avionics and flight systems requiring SEU-hardened logic, high I/O count and reliable serial links.
• Medical Electronics — Deterministic logic, on‑chip DSP resources and robust I/O for medical instrumentation and imaging applications.
• Nuclear Power Plant Control — Hardened registers and wide operating temperature accommodate control and monitoring equipment in nuclear environments.

Unique Advantages

• High Logic Capacity: 151,824 logic elements enable large-scale digital designs and complex control/state machines on a single device, reducing system BOM and board area.
• Deterministic Performance: 4-input LUTs with fast carry chains and fabric timing characterized up to 300 MHz support predictable timing for synchronous designs.
• Radiation‑Resistant Design: Hardened registers and configuration resistance to radiation-induced upsets improve mission reliability in harsh environments.
• Integrated High‑Speed I/O: 720 I/O pins plus 3.125 Gbps SerDes and DDR memory controller support simplify high-bandwidth interface designs.
• Military Temperature Qualification: −55 °C to 125 °C operating range and military grade listing support deployment in extreme-temperature and high-reliability applications.
• Compact, High‑Density Package: 1657-BCLGA (42.5×42.5 mm) surface-mount package provides a high pin-count footprint suitable for dense, complex systems.
