Plastic ARM-based microcontroller is space-ready
Frontgrade Technologies has developed a plastic-encapsulated version of its UT32M0R500 radiation-tolerant microcontroller aimed at space missions. Built around a 32-bit Arm Cortex-M0+ core, the plastic UT32M0R500 is set for flight grade production in July 2024 after meeting NASA’s PEM INST-001 Level 2 qualification.
Housed in a 14.5×14.5-mm, 143-pin plastic BGA package, the UT32M0R500 offers the same I/O configuration and features as its ceramic QML counterpart. It tolerates up to 50 krads of total ionizing dose (TID) radiation. For design flexibility, the device combines two independent CAN 2.0B controllers with mission read/write flash memory and system-on-ship functionality. This integration enables designers to manage board utilization, while reducing both cost and complexity.
“The proliferation of satellites for LEO missions is increasing the demand for highly reliable components with efficient SWaP-C characteristics and radiation assurances,” said Dr. J. Mitch Stevison, president and CEO of Frontgrade Technologies. “Adding another plastic device to our portfolio that is qualified to NASA’s Space PEM Level 2 strengthens our position as a trusted provider of high reliability, radiation-assured devices for critical space missions.”
The UT32M0R500 is supported by Arm’s Keil suite of embedded development tools.
