Atmel Launches First Rad Tolerant megaAVR MCU for Space Applications

(…) announced it is shipping the Atmel ATmegaS128 MCU targeting next-generation space applications. In addition to all the popular features of the megaAVR® family, the new ATmegaS128—the first uC Rad Tolerant device for Atmel—delivers full wafer lot traceability, 64-lead ceramic package (CQFP), space screening, space qualification according to QML and ESCC flow and total ionizing dose up to 30 Krad (Si) for space applications. The ATMegaS128 is “latch up” immune thanks to a dedicated silicon process: SEL LET > 62.5Mev at 125°C, 8MHz/3.3V. SEU to heavy ions is estimated to 10-3 error/device/day for Low Earth Orbit applications. With billions of commercial AVR devices widely deployed throughout the world, the new space-grade AVR family benefits from support of the Atmel Studio ecosystem and allows aerospace developers to use the industrial-version of the ATmega AVR to prototype their applications for a fraction of the cost. The ATmegaS128 is available in a ceramic hermetic packaging and is pin-to-pin and drop-in compatible with existing ATmega128 MCUs, allowing flexibility between commercial and qualified devices, enabling faster-time-to-market and minimizing development costs. With this cost-effective approach and a plastic Hirel-qualified version, the ATmegaS128 can be also considered in more general aerospace applications including class A and B avionic critical cases where radiation tolerance is also a key requirement.”
