Aspeed Ast2500 Datasheet Here

The datasheet lists the following external interfaces. Pay attention to voltage domains here.


The Aspeed AST2500 is not glamorous. It runs at 800MHz; it doesn't have multiple cores; its GPU is 2D-only. But when you read its datasheet line-by-line, you understand why it dominates the server BMC market: it is robust, well-documented, and impeccably designed for remote manageability.

Whether you are designing a switch, a storage array, or a router, the AST2500 datasheet provides everything you need to implement:

As server architectures move towards the Open Compute Project (OCP) and DC-SCM standards, the AST2500 remains a reference point for what a good BMC should be. For your next server motherboard layout or OpenBMC port, keep the AST2500 datasheet open on one monitor – it will answer 90% of your hardware questions.


Final Word: Always verify the revision of your AST2500 (e.g., AST2500-A2 vs. A3). As the datasheet’s revision history shows, later steppings fix errata related to USB hub stability and I2C clock stretching. Happy engineering.

    The Powerhouse Under the Hood: A Deep Dive into the ASPEED AST2500

    If you’ve ever peeked at the motherboard of a modern enterprise server from giants like Supermicro

    , you’ve likely seen a small, unassuming chip branded with the logo. That chip is the

    , the sixth generation of ASPEED’s Server Management Processor.

    While it doesn't run your databases or host your websites, it is the "brain" that keeps the server alive, manageable, and secure from miles away. Here is a breakdown of why this specific chip became an industry standard. 1. Performance and Efficiency The datasheet lists the following external interfaces

    The AST2500 represents a significant leap from its predecessors. It features an 800MHz ARM11 processor

    and was one of the first in its class to migrate memory support from DDR3 to DDR4 (up to 1600Mbps)

    . This boost ensures that remote management tasks—like loading heavy web-based interfaces or processing high-resolution video for iKVM—don't lag, even when the host system is under heavy load. 2. Integrated 2D Graphics One of the most practical features found in the AST2500 datasheet is the on-chip PCIe 2D VGA Local Display:

    It provides local display capability without needing an expensive, dedicated VGA add-on card. Remote Management:

    It supports remote video redirection, allowing admins to see exactly what’s on the server monitor via a browser, regardless of the OS state. 3. Comprehensive Connectivity

    The chip acts as a bridge between various communication protocols. According to technical discussions on , the AST2500 supports: Network Interfaces: Often paired with controllers like the Intel I210AT Realtek RTL8211E via RGRMII/NCSI for dedicated management traffic. LPC/eSPI Bridges: Essential for communicating with the host CPU and BIOS. UART/COM Ports: Providing serial console access for low-level debugging. 4. The Open Source Revolution: OpenBMC and u-bmc
