The Emerson/Motorola MVME2700 is a VME64 processor module built around the PowerPC 750 32-bit microprocessor running at 266 MHz. Designed for industrial and embedded applications requiring reliable computation in compact form factors, this module integrates 64 MB of ECC DRAM (expandable to 256 MB), 8 MB on-board Flash, and 1 MB socketed Flash storage. The processor features 32 KB/32 KB L1 cache and 1 MB backside L2 cache for efficient instruction and data handling.
