SAMRH71F20C-7GB-MQ

Microcontrollers Overview

The SAMRH71F20C-7GB-MQ is a rad-hard 32-bit microcontroller based on the ARM Cortex-M7 processor running at 100 MHz. It features 128 Kbytes of embedded Flash with ECC, 384 Kbytes of TCM SRAM, and 768 Kbytes of multiport SRAM. The device includes SpaceWire, MIL-STD-1553B, Ethernet MAC, and CAN-FD interfaces. Operating temperatures range from -55°C to +105°C for the TFBGA package.

Microcontrollers Feature Summary

• Radiation-tolerant design utilizing ATMX150RHA process for aerospace reliability
• Integrated SpaceWire router and MIL-STD-1553B interface for deterministic communication
• Hardened external memory controller supporting SDRAM with ECC
• Comprehensive safety mechanisms including hardware scrubbing and integrity check monitoring

Microcontrollers Applications

• On-board computing for critical space missions
• Sensor management in satellite systems
• Spacecraft connectivity and data handling

Microcontrollers Procurement Notes

Verify the specific revision code (C or E) required for your radiation tolerance specifications. Confirm that the TFBGA625 package meets your thermal and mechanical constraints. Ensure compatibility with existing aerospace supply chain requirements and quality certifications such as ESCC standards before finalizing procurement.

Microcontrollers Selection Notes

Select this component when high-performance processing combined with radiation hardness is mandatory. The integrated SpaceWire and 1553B links reduce external component count. Consider the extensive memory options if complex data analysis or large buffer storage is needed for autonomous operations.

Microcontrollers Part Context

Part of the SAMRH71 family designed specifically for harsh radiation environments. It leverages standard ARM Cortex-M7 architecture while adding hardened peripherals and error correction logic not found in commercial counterparts. This allows developers to use familiar tools while meeting strict aerospace compliance.

Microcontrollers Replacement Considerations

No direct public substitutes are listed. Evaluate other Microchip rad-hard MCUs like the SAMRH707 for lower performance needs or different pin counts. Verify that any alternative maintains the required SpaceWire and 1553B integration capabilities.
