The ESP750 Enhanced Space Processor card has been designed for LEO and GEO missions. This board represents MDA's 6th generation of space computers and is designed and built to the highest mission/safety critical space standards.

Featuring levels of integration normally found only on commercial products, the 3U Compact-PCI ESP750 Board provides high performance processing capabilities and I/O peripherals functions available through a front panel connector.

The card is built around the IBM PowerPC 750FX™ processor operating at up to 733MHz and includes Level 1 (L1) and Level 2 (L2) cache memory, on-board SDRAM, EEPROM, FLASH RAM, Built-In Test (BIT), a secure digital watchdog timer and a compliment of General Purpose I/O (GPIO), interrupt and timer functions.
