UT699E 32-bit Fault-Tolerant SPARC V8/LEON 3FT Processor


Log in for pricing

The UT699E is an enhanced version of the UT699 featuring a seven stage pipelined monolithic, high-performance, fault tolerant SPARCTM V8/LEON 3FT Processor. L1 cache has been increased to 16kB for both instruction and data caches.  Performance is increased to 1.2 DMIPS/MHz. RMAP protocol is supported for all four SpaceWire ports. Other enhancements include cache snooping. The UT699E provides a 32-bit master/target PCI interface, including a 16 bit user I/O interface for off-chip peripherals. A compliant 2.0 AMBA bus interface integrates the on-chip LEON 3FT, SpaceWire, Ethernet, memory controller, cPCI, CAN bus, and programmable interrupt peripherals.  The UT699E is SPARC V8 compliant; therefore, developers may use industry standard compilers, kernels, and development tools. A full software development suite is available including a C/C++ cross-compiler system based on GCC and the Newlib embedded C-library. Software developed for the UT699 will be 100% compatible with the UT699E.  BCC includes a small run-time kernel with interrupt support and Pthreads library. For multi-threaded applications, a SPARCTM compliant port of the eCos real-time kernel, RTEMS 4.x, and VxWorks 7.x is supported.
