The AST2500 is found across a wide range of server platforms. generation systems use the AST2500 as their BMC, providing VGA output at 1920 × 1200 resolution with 1 GB of DDR4 memory. The chip supports dedicated 1 GbE management networking alongside NCSI (Network Controller Sideband Interface) for shared port management.
| Parameter | Specification | |---|---| | CMOS I/O voltage | 2.5 V / 1.8 V DC | | DACRSET external resistor | 18 kΩ | | IV11D internal voltage | 1.15 V (revised from 1.1 V) | | PLL power ball | T11 (requires isolated power rail with low noise) |
Whether you are designing a switch, a storage array, or a router, the AST2500 datasheet provides everything you need to implement: Aspeed Ast2500 Datasheet
Supports RGMII and RMII configurations to connect with physical layer transceiver (PHY) chips or NC-SI (Network Controller Sideband Interface) sideband links shared with standard server NICs. 4. Hardware Monitoring and Peripherals
Multiple versions of the AST2500 datasheet have been indexed by technical document repositories:
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.

One of the most vital sections of the datasheet covers the Integrated Remote Console (iKVM), which allows for "lights-out" management.
The Aspeed AST2500 is a single-chip BMC that integrates multiple functions, including a 32-bit ARM Cortex-A9 processor, memory interfaces, and a rich set of peripherals. The chip supports a wide range of interfaces, including USB, UART, I2C, SPI, and PCIe, making it an ideal solution for managing complex server systems. The AST2500 is designed to operate in a variety of environments, with a temperature range of -40°C to 85°C and a voltage range of 3.3V to 5V.
: It operates on standby power ("always-on"). The chip supports dedicated 1 GbE management networking
: Redirects USB devices (keyboard, mouse, storage) over the network.
