The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronic Solutions. The successor of the RAD6000, the RAD750 is for use in high radiation environments such as experienced on board satellites and spacecraft. The RAD750 was released in 2001, with the first units launched into space in 2005.
The CPU has 10.4 million transistors, nearly an order of magnitude more than the RAD6000 (which had 1.1 million). It is manufactured using either 250 or 150 nm photolithography and has a die area of 130 mm² It has a core clock of 110 to 200 MHz and can process at 266 MIPS or more. The CPU can include an extended L2 cache to improve performance. 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. 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.
The RAD750 system has a price that is comparable to the RAD6000 which is US$200,000 per board (per 2002 reference). However customer program requirements and quantities will greatly affect the final unit costs.
The RAD750 is based on IBM's PowerPC 750. Its packaging and logic functions are completely compatible with the PowerPC 7xx family.
