TheRAD750 is aradiation-hardenedsingle-board computer manufactured byBAE Systems Electronics, Intelligence & Support.[1] The successor of theRAD6000, the RAD750 is for use in high-radiation environments experienced on boardsatellites andspacecraft.[2] The RAD750 was released in 2001, with the first units launched into space in 2005.[1][3]
TheCPU has 10.4 milliontransistors, an order of magnitude more than the RAD6000 (which had 1.1 million).[3] It is manufactured using either 250 or 150nmphotolithography and has adie area of 130 mm2.[1] It has acore clock of 110 to 200 MHz and can process at 266 MIPS or more.[1] The CPU can include an extendedL2 cache to improve performance.[3]The CPU can withstand an absorbed radiation dose of 2,000 to 10,000 grays (200,000 to 1,000,000 rads), temperatures between −55 °C and 125 °C, and requires 5 watts of power.[1][3] The standard RAD750 single-board system (CPU andmotherboard) can withstand 1,000 grays (100,000 rads), temperatures between −55 °C and 70 °C, and requires 10 watts of power.[3]
The RAD750 system has a price that is comparable to the RAD6000, the latter of which as of 2002 was listed at US$200,000 (equivalent to $349,639 in 2024).[4] Customer program requirements and quantities, however, greatly affect the final unit costs.[citation needed]
The RAD750 is based on thePowerPC 750.[1] Its packaging and logic functions are completely compatible with thePowerPC 7xx family.[3]
The termRAD750 is a registered trademark of BAE Systems Information and Electronic Systems Integration Inc.[5]
In 2010, it was reported that there were over 150 RAD750s used in a variety of spacecraft.[6] Notable examples,[2] in order of launch date, include:
