The RAD750 is a radiation-hardened single-board computer manufactured by BAE Systems Electronics, Intelligence & Support.
Technology
The CPU has 10.4 million
, an order of magnitude more than the RAD6000 (which had 1.1 million).
It is manufactured using either 250 or 150
nanometre photolithography and has a die area of 130 mm
2.
It has a
clock rate of 110 to 200
megahertz and can process at 266 MIPS or more.
The CPU can include an extended L2 cache to improve performance.
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 °
Celsius and 125 °C, and requires 5 watts of power.
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.
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 ().
The RAD750 is based on the PowerPC 750.
