The Emerson/Motorola MVME2100-1 is a VMEbus Single Board Computer built on the MPC8240 PowerPC microprocessor, engineered for embedded systems in industrial automation, telecommunications, medical, scientific, and imaging applications. This VME64-compliant processor module delivers modular expansion through one 32-bit PMC slot and three 32-bit PC•MIP slots, enabling field-configurable I/O architectures. The design integrates 10/100Base-TX Ethernet, RS-232 serial ports, a real-time clock with NVRAM, and dual DMA channels, making it suitable for demanding embedded control and data acquisition tasks.
