Datasheet New: Aspeed Ast2500

The ASPEED AST2500 is a cornerstone of modern data center infrastructure, serving as a 6th-generation Server Management Processor. As a specialized System-on-Chip (SoC), it functions as a Baseboard Management Controller (BMC), providing critical out-of-band management that allows administrators to monitor and control servers regardless of the operating system's state.

  • Pin L5 (JTAG_TRST_N): Previously "Reserved", now defined as "Reset Filter Bypass". Tying this high during boot disables the optional reset deglitch filter (useful for debug).
  • Pin G7 (MAC2_LINK): Now supports "Wake-on-LAN" direct signaling without waking the entire ARM core.
