The RadiSys EPC-26A is a PC/AT-compatible CPU module built on the EMC form factor for embedded applications requiring industrial-grade processing and reliability. It centers on an Intel 486DX2 processor running at 50 MHz paired with the Pico-Power Redwood 2-chip chipset (176-pin TQFP). The module meets UL-1950 safety and low EMI standards, with filter networks and ESD protection on all front-panel accessible ports.
