Insights
Microchip released a radiation-tolerant CAN FD transceiver supporting up to 5 Mbps and space-grade protections.
Microchip delivers the ATA6571RT as a pin‑compatible, radiation‑tolerant CAN FD transceiver built for satellites and spacecraft. It raises link throughput to 5 Mbps and supports 64‑byte frames, while remaining backward compatible with classic CAN. The device includes CRC error checking, Single‑Event Effects resistance, Total Ionizing Dose tolerance, short‑circuit protection and overtemperature safeguards.
The business effect flows from clearer system integration and reduced bus load when replacing 1 Mbps CAN parts with this 5 Mbps device. Adoption depends on subsystem validation, flight heritage requirements and qualification cycles for space programs. The part targets platform data handling, propulsion and robotics, so procurement decisions will hinge on qualification status and integration testing timelines.
Watch for evidence of formal space‑qualification, flight acceptance on a named mission and distributor uptake over the next 6–24 months. Note the published unit price of
