Microchip Technology has introduced, what the company claims, is the first space-qualified Ethernet transceiver.

The VSC8541RT is a radiation-tolerant device based on a COTS solution that has been widely used in other industries.

The company has also received final qualification for its new Arm Cortex-M3-based SAM3X8ERT radiation-tolerant MCU and embedded Ethernet controller. The two products can be used for space applications separately or together.

Both devices feature enhanced characterized levels of radiation performance and high-reliability quality flow and are available in both plastic and ceramic packages. They both offer the same pin-out distribution to allow the use of COTS devices before moving to space-grade components to reduce development time and cost.

The VSC8541RT transceiver is a single-port Gigabit Ethernet copper PHY with GMII, RGMII, MII and RMII interfaces and verified and documented radiation performance. It is latch-up immune up to 78 Mev; TID has been tested up to 100 Krad. With the same rad-tolerant die and package, a 100 MB limited bitrate performance VSC8540RT is also available in plastic and ceramic qualified versions.

The SAM3X8ERT MCU delivers 100 DMIPS from the same ecosystem as the industrial variant. It features up to 512 Kbyte Dual Bank Flash, 100 Kbytes SRAM, ADC & DAC and dual CAN controller as well as its Ethernet capability.

The Arduino Due commercial kit can be used to support the SAM3X8ERT along with the VSC8541EV evaluation boards for the VSC8541RT. The SAM3X8ERT device is supported by Atmel Studio IDE for developing, debugging and software libraries.
