Atmel announced that it will deliver ATmegaS128 MCUs for the next generation of space applications. In addition to all the popular features of the established megaAVR series, the new ATmegaS128 – the first µC radiation-resistant device for Atmel – also features full wafer batch traceability, 64-lead ceramic packaging (CQFP), space screening ESQ flows and total ionizing doses up to 30 Krad (Si) in QML-compliant and space-certified space applications. Thanks to a special silicon process, ATMegaS128 has a "latch" immunity function: SEL LET> 62.5Mev at 125C, 8MHz / 3.3V. For low earth orbit applications, the SEU for heavy ions is estimated to be 10-3 errors / equipment / day.
With billions of commercial AVR devices deployed worldwide, the new space-grade AVR series benefits from the support of the Atmel Studio ecosystem and enables aerospace developers to use the industrial version of ATmega AVR to prototype their applications Make a part. cost. ATmegaS128 is packaged in a ceramic hermetic package, pin-to-pin compatible with existing ATmega128 MCUs, and directly compatible with them, thus providing flexibility between commercial and qualified devices, speeding time to market and minimizing Development costs. With this cost-effective method and a plastic Hirel-certified version, ATmegaS128 can also be considered for use in more general aerospace applications, including Class A and B avionics critical situations, and radiation tolerance is also a key requirement.
"With nearly three decades of aerospace experience, we are excited to bring one of our most popular MCU cores, the AVR MCU, to space," said Patrick Sauvage, general manager of the aviation business unit at Atmel Corporation. "By leveraging our proven Atmel AVR core and ecosystem to improve radiation performance, the new ATmegaS128 provides developers with a smaller footprint, lower power consumption and full analog integration for space applications, such as motor and sensor control And payload and platform data processing capabilities. We look forward to putting more Atmel solutions into space. "

Ecosystem and Starter Kits-To simplify the design process and speed time to market, Atmel provides a complete STK600 starter kit and development system for ATmegaS128 AVR MCUs, allowing designers to quickly begin developing prototypes and advanced design features on AVR Code. Test the new design. Users can also start from the industrial version of ATmega128 (with the exact pins of ATmegaS128) to save costs. The new AVR is supported by the mature Atmel Studio IDP for developing and debugging Atmel | SMART ARM processor-based MCUs and Atmel AVR MCU applications and the Atmel software framework.
