The ACTIS Computer VSBC-6872/FHE-A is a high-performance Single Board Computer built around the Freescale MPC8270 PowerQUICC II processor running at 450 MHz with throughput up to 855 MIPS. Engineered for embedded systems requiring substantial computational capacity in a compact form factor, this VMEbus-based platform integrates dual-port SRAM, battery-backed real-time clock, and multiple serial communication interfaces alongside three Fast Ethernet ports and a PMC mezzanine slot.
Technical Specifications
