Aspeed Ast2500 Datasheet
The AST2500 is a highly integrated server management processor built on an advanced ARM architecture designed to minimize power consumption while maximizing independent system control. ARM1176JZF-S core. Clock Speed: Up to 800 MHz.
) pins to prevent digital switching noise from skewing ADC sensor readings.
: Dual 10/100/1000 Mbps Gigabit Ethernet MACs.
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). Aspeed Ast2500 Datasheet
Modern server management requires robust security, and the AST2500 datasheet documents several hardware security capabilities. The chip includes:
You are integrating the AST2500 onto a motherboard for a custom server or industrial controller.
The memory controller provides a 16-bit data bus width. It supports a total capacity of up to 1 GB, including an optional Error-Correcting Code (ECC) configuration. It accommodates two main memory types: : Operating at speeds up to 800 Mbps. DDR4 SDRAM : Operating at speeds up to 1600 Mbps. Flash Memory Layout The AST2500 is a highly integrated server management
Short conclusion The AST2500 is a central component for BMC-driven remote management in many servers; the datasheet is essential for hardware, firmware, and platform engineers to ensure correct integration, reliable boot, and secure operation.
