Atmel's new LEON based rad-hard SPARC processor improves speed versus power consumption ratio by eight
Atmel Corporation has announced the availability of the AT697, a new generation of radiation hardened 32-bit SPARC processor (V8) for the space industry. Compared to the former SPARC processors, the AT697 improves the speed versus power consumption ratio by eight, providing the spacecraft computers with an increased calculation capacity in a three-time smaller package. The AT697 is also software compatible with the previous Atmel SPARC processors, including the SPARC V7 TSC695F, which are today widely used in flight as the central component of the spacecraft computers.
The AT697 processor implements the LEON2 FT (fault tolerant) VHDL model. It is produced on Atmel's 0.18 um CMOS process in Atmel's France manufacturing site. It includes a SPARC V8 Integer Unit, a Floating Point Unit, separate instruction and data caches, a PCI interface and a flexible memory controller that can interface with SRAM, PROM and SDRAM.
