Radiation-hardened computer (2001) From Wikipedia, the free encyclopedia
The RAD750 is a radiation-hardened single-board computer manufactured by BAE Systems Electronics, Intelligence & Support.[1] The successor of the RAD6000, the RAD750 is for use in high-radiation environments experienced on board satellites and spacecraft.[2] The RAD750 was released in 2001, with the first units launched into space in 2005.[1][3]

The CPU has 10.4 million transistors, an order of magnitude more than the RAD6000 (which had 1.1 million).[3] It is manufactured using either 250 or 150 nm photolithography and has a die area of 130 mm2.[1] It has a core clock of 110 to 200 MHz and can process at 266 MIPS or more.[1] The CPU can include an extended L2 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 and motherboard) 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 $338,797 in 2023).[4] Customer program requirements and quantities, however, greatly affect the final unit costs.[citation needed]
The RAD750 is based on the PowerPC 750.[1] Its packaging and logic functions are completely compatible with the PowerPC 7xx family.[3]
The term RAD750 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:
