The TSC695F (ERC32 Single-Chip) is a highly integrated, high-performance 32-bit RISC embedded processor implementing the SPARC architecture V7 specification. It has been developed with the support of the ESA (European Space Agency), and offers a full development environment for embedded space applications. The processor is manufactured using the Atmel 0.5 m radiation tolerant ( 3 00 KRADs ( Si)) CMOS enhanced process (RTP). It has been specially designed for space, as it has on-chip concurrent transient and permanent error detection. The TSC695F includes an on-chip Integer Unit (IU), a Floating Point Unit (FPU), a Memory Controller and a DMA arbiter. For real-time applications, the TSC695F offers a high security watchdog, two timers, an interrupt controller, parallel and serial interfaces. Fault tolerance is supported using parity on internal/external buses and an EDAC on the external data bus. The design is highly testable with the support of an On-Chip Debugger (OCD), and a boundary scan through JTAG interface.
