Space-qualified, Low-power SBC Offers 1.0 GHz Processing

AIT_0817-AThe SP0, a space-qualified, radiation-tolerant 3U CompactPCI SBC from Aitech, performs at an exceptionally low power of only 10 W for manned spacecraft and unmanned satellite subsystems and platforms. The compact MPC8548E, PowerQUICC-III PowerPC-based SBC provides high levels of on-board functionality and integration combined with low power dissipation. It can achieve a processing speed of 1.17 GHz and 333.3 MHz of core complex bus and DDR-1 memory speeds, while adhering to the low power and small form factor requirements necessary in most satellite and spacecraft, mission-critical applications. The SP0's processor includes an e500 SoC integrating both an L1 cache with 32 KB instruction and 32 KB data, and a 512 KB L2 cache. The large on-board memory also includes up to 512 MB of fast DDR1 SDRAM with ECC protection for high data integrity as well as 512 KB of redundant Boot Flash, two Gigabit Ethernet ports and four asynchronous, high-speed serial communications ports.
