RAD750

The RAD750 is a radiation- resistant single-board computer manufactured by BAE Systems Electronic Solutions. As the successor of RAD6000, the RAD750 for use in environments with high levels of radioactivity, as developed on board satellites and spacecraft. The RAD750 was published in 2001, the first units were started in 2005 in space.

Overview

The CPU has 10.4 million transistors, almost an order of magnitude more than its predecessor RAD6000 ( 1.1 million ). It has a chip area of 130 mm ². He has a core clock from 110 to 200 MHz and can process 266 MIPS or more. The CPU may also include an enhanced L2 cache to improve performance. The processor itself can 200000-1000000 rd withstand ( 2,000 to 10,000 Gy), withstand temperature ranges from -55 to 125 ° C and requires 5 watts of power. The default RAD750 single board computers ( CPU and motherboard ) can 100,000 rd ( 1,000 Gy ) and the temperature range of -55 and 70 ° C to withstand and requires 10 W of power.

A RAD750 system has a RAD6000 comparable with the price of about $ 200,000 per board (as of 2002). However, the program needs of the customer and the purchase quantities large impact on the final cost per unit.

The RAD750 is based on the IBM PowerPC 750 Its packaging and logic functions are fully compatible with the PowerPC 7xx family.

Use

There are several spacecraft with RAD750 computers in operation. The comet Deep Impact probe, which was launched in January 2005, was the first spacecraft with a RAD750 computer. Two RAD750 computers are used in the WorldView-1 satellite, which draws high-resolution images of the Earth. Started this was on 18 September 2007. WorldView-1 is part of the National Geospatial -Intelligence Agency Nextview program.
