Atmel has worked with the European Space Agency �ESA) to develop a new radiation-hardened SPARC processor for space applications delivering 90 MIPs at 100 MHz over full temperature and voltage ranges for only 0.7W.
The AT697 Revision F is the fully radiation hardened version of the SPARC V8 architecture achieving 100 MHz operation for only 0.7W with radiation performance of a total dose tested up to 300 Krad, three times the previous version.
It is extremely reliable against Single Event Upset and Transients, with SEU and SET induced error rate better than 10-5 errors/device/day, and has no single event latch-up below a LET threshold of 95 MeV.cm²/mg @ 125°C.
The design is based on the ESA LEON2-FT �Fault Tolerant model and includes the latest techniques of radiation hardening by design including Full Triple Modular Redundancy, EDAC and parity bit protections. The European Space Agency has supported the design of this product.
With its 90 MIPs (Dhrystone 2.1) and 23 MFlops (Whetstone) high performance, the AT697F offers the industry’s best computing power efficiency of 150 MIPs per Watt. The AT697F is software compatible with the other Atmel space SPARC processors and has drastically improved the SDRAM interface efficiency, running at up to 90 MHz.
Samples of the AT697F are available in a MCGA349 package as well as in a MQFPF256 package. The AT697F package versions are pin out compatible with those of the AT697E. Flight models will be delivered and tested to QML Q&V and ESCC quality flows in December 2009.
