Microchip has released its new radiation-tolerant (RT) CAN FD transceiver ATA6571RT, a high-reliability communication solution tailored for space systems. Designed to support flexible data rates of up to 5 Mbit/s, the device enables efficient data exchange in satellites, spacecraft, and other mission-critical platforms where reliability and fault tolerance are paramount.The ATA6571RT represents a significant advancement over traditional CAN interfaces, which typically offer a bandwidth of only 1 Mbit/s. With data frames of up to 64 bytes, it delivers higher throughput, improved efficiency, and reduced bus load. Fully backward-compatible with classical CAN, the new transceiver ensures seamless integration into existing designs.

Enhanced with a cyclic redundancy check (CRC) mechanism for improved error detection, the ATA6571RT supports safe and reliable operation in critical space systems such as propulsion control, platform data handling, onboard computing for nanosatellites, robotics, and sensor bus management. The RT version maintains pin compatibility with existing COTS plastic and ceramic variants for easy PCB integration.Leon Gross, Corporate Vice President for Aerospace and Defence at Microchip, commented: “The ATA6571RT is a cost-effective, compact and power-efficient component developed to meet the rigorous demands of space environments. As a leading supplier in the aerospace and defence sector, we are proud to deliver solutions that support both near-Earth and deep-space missions.”

The transceiver is hardened against single-event effects (SEE) and total ionizing dose (TID) radiation and includes low-power management with local and remote wake-up functions, as well as short-circuit and overtemperature protection.With the ATA6571RT, Microchip expands its portfolio of radiation-tolerant communication interfaces, which also includes solutions for Ethernet, MIL-STD-1553, and SpaceWire. This launch underlines the company’s commitment to advancing secure, high-performance connectivity for aerospace and defence applications.The ATA6571RT is available at a unit price of 210 USD (for orders of 10 units or more). Additional details and purchasing options are available through Microchip’s sales representatives, authorized distributors, or via the company’s website at www.microchipdirect.com.
