AT697F-KG-E 技术参数

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 on-chip Integer Unit (IU), a Floating Point Unit (FPU), separate instruc-

tion and data caches, hardware multiplier and divider, interrupt controller, debug support unit

with trace buffer, two 32-bit timers, Parallel and Serial interfaces, a Watchdog, a PCI Interface

and a flexible Memory Controller. The design is highly testable with the support of a Debug Sup-

port Unit (DSU) and a boundary scan through JTAG interface.

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 0.18 µm CMOS process. It has been especially

designed for space, by implementing on-chip concurrent transient and permanent error detec-

tion and correction.

The AT697F is pinout compatible with the AT697E.

Refer to section “Differences between AT697F and AT697E”, page 146“ for detailed description

of the differences between AT697F and AT697FE.
