Atmel Space Rad-Hard
Processors
Our Unrivalled Flight Heritage
Atmel® Aerospace components are all fully designed, assembled, tested, and qualified in Europe.
Over the last 16 years, Atmel has steadily built a space microprocessor strategy based on the SPARC® architecture. With
worldwide sales of over 3000 flight models featuring the Atmel TSC695—and already over 1000 flight models with the
Atmel AT697F—the Atmel SPARC processor roadmap boasts an unrivalled flight heritage.
The Atmel Rad-Hard SPARC V8 Processors comprises a unique solution that combines a powerful 100MHz radiation-
hardened processor and a reprogrammable SRAM-based FPGA. It offers the industry’s best reconfigurable solution for
in-flight space applications.
The Atmel AT7913E SpaceWire Remote Terminal Controller is a highly integrated processor delivering lower power con-
sumption and reduced size thanks to full system-on-chip integration. Based on the LEON2FT processor core, the AT7913E
embeds a 64KB EDAC protected on-chip memory and ADC/DAC, CAN and SpaceWire interfaces.
