Aspeed Ast2500 Datasheet New ((link)) Online
Overview — ASPEED AST2500 (new datasheet summary)
Key description
ASPEED AST2500 is a server-management SoC integrating a multi-core ARM processor, a BMC-focused feature set (IPMI/KCS/Redfish-capable firmware platforms), graphics and video compression, extensive I/O for system management, and low-power operation for rack and edge servers.
Open Source Ecosystem: The AST2500 is a cornerstone for the OpenBMC project, allowing developers to build custom, transparent management firmware on a reliable hardware foundation. aspeed ast2500 datasheet new
4. DDR4 Video Memory Timings
Older datasheets listed generic DDR4 parameters. The new revision provides vendor-specific timing tables for Micron MT40A256M16 and Samsung K4A8G165WB. If you are experiencing graphical glitches over IPMI, cross-referencing these exact timings is now mandatory. Overview — ASPEED AST2500 (new datasheet summary) Key
At its heart, the AST2500 utilizes an 800MHz ARM11 processor. A significant leap from its predecessors was the transition from DDR3 to DDR4 memory support, reaching speeds of up to 1600Mbps. This shift allows for the higher performance overhead required by increasingly complex modern server environments. Key Hardware Features According to official ASPEED documentation Supports DDR3L or DDR4 SDRAM (external) Memory frequency
Enterprise Servers: Providing standard IPMI 2.0 compliant management.
A robotics company in Ohio was about to scrap 10,000 legacy industrial PCs because their remote management chips were "obsolete." The new AST2500 datasheet proved otherwise. By reconfiguring the LPC (Low Pin Count) bus using the newly documented "Multi-PHY mode," those old BMCs could talk to CAN bus controllers and Modbus sensors directly.
2.3. Memory Controller
- Supports DDR3L or DDR4 SDRAM (external)
- Memory frequency up to 800 MHz (DDR3L) or 1066 MHz (DDR4)
- Maximum capacity often 1–2 GB (depending on design)
