CAES UT700 LEON Microprocessor

Based on the industry-standard SPARC V8 architecture, the UT700 32-bit Fault Tolerant microprocessor is a system-on-chip and features a seven-stage pipelined monolithic, high performance, fault-tolerant SPARC V8/LEON3FT Processor.

The UT700 is part of the LEON product family that has a long lineage in the space industry.

Targeted for applications such as spacecraft on-board computers, payload processing, nuclear power plant controllers, critical transportation systems, high-altitude avionics, and medical electronics and X-ray cargo scanning.

CAES’s UT700 LEON3FT is SPARC V8 compliant so developers may use industry standard compilers, kernels and development tools. A full software development suite is available.

UT700-LEAP

The CAES UT700-LEAP evaluation board and mezzanine companion cards provides a flexible development platform for customers for accelerated development at a minimal cost. The LEAP has a CAES UT700 LEON 3 FT prototype grade device with 8 Mbytes NV memory storage and 32Mbytes SDRAM (both commercial memory), along with one USB UART interface and one 10T/100 Mbit/s Ethernet port. It also includes a JTAG interface for programming and debug of UT700 LEON 3FT (requires XILINX USB Platform Cable) along with one 192-pin mezzanine card expansion connector and an on-board Programmable LEAP main clock.
