AT697F

7703E–AERO–08/11

Description

The AT697F is a highly integrated, high-performance 32-bit RISC embedded processor

based on the SPARC V8 architecture. The implementation is based on the European

Space Agency (ESA) LEON2 fault tolerant model. By executing powerful instructions in

a single clock cycle, the AT697F achieves throughputs approaching 1MIPS per MHz,

allowing the system designer to optimize power consumption versus processing speed.

The AT697F is designed to be used as a building block in computers for on-board

embedded real-time applications. It brings up-to-date functionality and performance for

space application.

The AT697F only requires memory and application specific peripherals to be added to

form a complete on-board computer.

The AT697F contains an Integer Unit (IU), a Floating Point Unit (FPU), separate instruc-

tion and data caches, a hardware multiplier and divider, an interrupt controller, two 32-

bit timers and a watchdog, two UARTs, a general-purpose I/O interfaces, a PCI Inter-

face and a flexible memory controller. The design is highly testable with support from an

embedded Debug Support Unit (DSU) with trace buffers and a JTAG interface for

boundary scan.

An idle mode holds the processor pipeline and allows Timer/Counter, Serial ports and

Interrupt system to continue functioning.

The processor is manufactured using the Atmel ATC18RHA CMOS process. It has been

especially designed for space by implementing on-chip concurrent transient and perma-

nent error detection and correction.

The AT697F is pinout compatible with the AT697E.
