Aspeed Ast2500 Datasheet – No Ads

PCIe Gen 2.0 x1 interface for direct, high-bandwidth communication with the host processor/chipset.

Primarily runs Linux-based BMC firmware like OpenBMC . Key Features & Benefits AST2500 - ASPEED Technology

The ASPEED AST2500 operates as an autonomous, out-of-band management subsystem. It functions independently of the host CPU's state (whether operating, suspended, or completely powered off). The chip acts as a secure, secondary computer on the server motherboard. It continuously interfaces with environmental sensors, voltage rails, and power supply units (PSUs).

The is the most comprehensive publicly accessible version, running to 841 pages and covering: specifications, functional descriptions, pin definitions, electrical characteristics, application circuits, and register maps. Aspeed Ast2500 Datasheet

: Uses an optimized compression engine for real-time Remote Keyboard, Video, and Mouse (KVM) redirection over IP. 3. Peripheral Interfaces and Connectivity

Supports DDR3 (800Mbps) and DDR4 (1600Mbps) with a 16-bit bus. PCIe Gen 2

The ASPEED AST2500 is an designed primarily for server management, out-of-band (OOB) management, and KVM-over-IP functionality. Part of the AST2500/AST2520 series, it is developed by ASPEED Technology Inc. to act as a system-on-chip (SoC) that manages server health, provides video output, and allows administrators to control servers remotely, even if the primary host CPU is powered down or unresponsive. 2. Key Specifications from the AST2500 Datasheet

The absolute first page an engineer should look at is the . Here is the breakdown of what the AST2500 datasheet block diagram actually tells you.

Widely adopted with strong software support (e.g., OpenBMC). It functions independently of the host CPU's state

The following key specifications and features are highlighted in the official datasheet:

The is the industry-standard "brain" behind modern server management. This 6th-generation Server Management Processor acts as a Baseboard Management Controller (BMC) , allowing administrators to monitor, troubleshoot, and power-cycle servers remotely without physical access. Core Technical Specs Processor: 800MHz ARM11 CPU.

Emulates a USB 2.0 human interface device (HID) and storage controller to the host system.

The AST2500 has two dedicated Thermal Diode inputs (D1P/D1N). These are designed for reading CPU substrate diodes (transistor junction voltage). Do not plug a standard thermistor (10k NTC) into these pins—the biasing current is wrong. Use the standard ADC pins for thermistors.
