Aspeed Ast2500 Datasheet New Verified May 2026

Unlocking the BMC: A Deep Dive into the New ASPEED AST2500 Datasheet

• Core Processor: ARM926EJ-S CPU running at 800MHz (compared to 400MHz on AST2400). The new datasheet clarifies dynamic voltage scaling to reduce heat under low load.
• Graphics: Integrated 2D graphics controller with hardware cursor. Supports up to 1920x1200 @ 60Hz (DisplayPort) and 1280x1024 (VGA). New note: The latest revision adds timing corrections for 4K H.264 decoding via the dedicated video engine.
• Memory: DDR4 DRAM controller (up to 1GB) or DDR3L (up to 2GB). Critical update in the new datasheet: Supported DDR4 part numbers are strictly limited to x16 organizations; x8 are not supported without a heat sink.
• PCIe: PCIe Gen2 x1 (Root Complex or Endpoint mode). New Errata: Under heavy USB 2.0 traffic, PCIe link retraining may require a specific 10ms delay during system reset.

Verdict for new designs: The AST2500 is superior for legacy LPC (Low Pin Count) interfaces and extreme temperature ranges (-40°C to +105°C vs AST2600's -20°C to +95°C).

Memory Support:

Supports both DDR3 (800Mbps) and DDR4 (1600Mbps) SDRAM with a 16-bit data bus and optional ECC, accommodating up to 1GB of memory. aspeed ast2500 datasheet new
