Aspeed Ast2500 Datasheet New !!better!!

ASPEED AST2500 is the 6th generation of Server Management Processors, functioning primarily as a Baseboard Management Controller (BMC)

The AST2500 is supported by a rich and mature software ecosystem:

Access, monitor, and diagnose servers via Console Redirection and Keyboard/Video/Mouse (KVM) over IP.

Before diving into pinouts, it is vital to understand the market position. The AST2500 is the successor to the legendary AST2400. The "new" datasheet interest stems from three distinct factors:

As a specialized BMC, the AST2500 is a core component for remote server management. It operates through the Intelligent Platform Management Interface (IPMI) , providing system administrators with tools for: Remote KVM (Keyboard, Video, Mouse) aspeed ast2500 datasheet new

The , ASPEED’s 7th generation BMC, launched in late 2019 and offers significant performance and security improvements. However, the AST2500 remains a compelling choice for cost-sensitive and mature designs.

: Supports DDR3/DDR4 SDRAM (up to 1600Mbps), providing the necessary bandwidth for complex management firmware like OpenBMC or AMI MegaRAC.

Supports up to 1GB of DDR3 (800Mbps) or DDR4 (1600Mbps) SDRAM with a 16-bit data bus width and an ECC option.

: It features a built-in PCIe 2D Graphics engine that supports resolutions up to at 60Hz with 32bpp, ensuring clear remote console access. ASPEED AST2500 is the 6th generation of Server

: Providing standard IPMI 2.0 compliant management.

At its heart, the AST2500 utilizes an . 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

The is an ARM-based SoC (System on Chip) designed specifically for server management, often referred to as a BMC or IPMI (Intelligent Platform Management Interface) controller. It acts as a dedicated processor responsible for monitoring the physical state of a server—temperature, fan speed, power status, and operating system status—independent of the main CPU and OS.
