SPARC processor delivers 90 MIPS @100MHz
Keywords:processor? space application? Atmel SPARC?
The AT697F has been total dose tested up to 300Krad. It is also reliable against single event upset and transient with induced error rate better than 10-5 errors/device/day. It does not exhibit single event latch-up below a LET threshold of 95MeVcm2/mg @125C.
The design is based on the European Space Agency's LEON2-Fault Tolerant model and includes the latest techniques of radiation hardening 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 23MFlops (Whetstone) high performance, the AT697F offers computing power efficiency of 150 MIPs/W. The AT697F is software compatible with the other Atmel space SPARC processors and has improved SDRAM interface efficiency, running at up to 90MHz.
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. The AT697F engineering models, in all package versions, are available now. The AT697F processor flight models will be delivered and tested to QML Q&V and ESCC quality flows in December 2009.
