The RadiSys EPC-2 386 Embedded Computer is a dual-slot, C-size VXI module built on IBM PC Architecture that functions as a VXIbus System Controller or Resource Manager in industrial embedded applications. Built around an Intel 386DX processor running at 20 MHz, it delivers deterministic control and data processing within standard VXIbus chassis. The module generates a 16 MHz SYSCLK signal for bus synchronization, manages bus arbitration and timeout detection, and initiates interrupt-acknowledge daisy chains. In Slot 0 configuration, it produces 10 MHz ECL CLK10 signals and controls MODID module identification.
