The AT697E is a highly-integrated, high-performance 32-bit RISC embedded proces-
sor implementing the SPARC architecture V8 specification. The implementation is
based on the European Space Agency (ESA) LEON2 fault tolerant model.
The processor is manufactured using the Atmel standard 0.18 碌m CMOS commercial
process. It operates at a low voltage. It has been especially designed for space, as it
has on-chip concurrent transient and permanent error detection.
The AT697E includes an on-chip Integer Unit (IU), a Floating Point Unit (FPU), sepa-
rate instruction and data caches, hardware multiplier and divider, interrupt controller,
debug support unit with trace buffer, two 24-bit timers, Parallel and Serial interfaces,
Idle mode function, Watchdog, a PCI Interface and a flexible Memory Controller.
The design is highly testable with the support of a Debug System Unit (DSU) and a
boundary scan through JTAG interface.
