The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronic Solutions.[1] The successor of the RAD6000, the RAD750 is for use in high radiation environments such as 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, nearly 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 itself can withstand 200,000 to 1,000,000 rads (2,000 to 10,000 gray), temperature ranges 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 100,000 rads (1,000 gray), temperature ranges 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 which is US$200,000 per board (per 2002 reference).[4] However customer program requirements and quantities will greatly affect the final unit costs.

The RAD750 is based on IBM's PowerPC 750.[1] Its packaging and logic functions are completely compatible with the PowerPC 7xx family.[3]

Deployment

There are several spacecraft in operation using RAD750 computers.[2]

As of 2010 there are over 150 RAD750s used in a variety of spacecraft.[5]
