Preliminary
Description
The TSC695FL (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 碌m radiation tolerant (魯 300
KRADs (Si)) CMOS enhanced process (RTP). It can operate at a low voltage for opti-
mized power consumption (see datasheet TSC695FL). It has been specially designed
for space, as it has on-chip concurrent transient and permanent error detection.
The TSC695FL includes an on-chip Integer Unit (IU), a Floating Point Unit (FPU), a
Memory Controller and a DMA arbiter. For real-time applications, the TSC695FL
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.
The TSC695FL is a selection of the TSC5695F performed for a narrow 3.3V biasing
voltage range (鹵 0.15V), as such, this specification can be only met by the products
solds as TSC695FL. Where computing power is not the key factor, it allows for a dra-
matic power consumption reduction (70%).
