Features a multi-channel 10-bit ADC engine used for monitoring precise system voltage rails, battery levels, and thermal thermistors.
The Aspeed AST2500 is a 7th-generation server management processor. It is a System-on-Chip (SoC) specifically designed for BMC applications. Unlike general-purpose microcontrollers, the AST2500 integrates a rich set of I/O, a high-performance 2D graphics controller, and a video capture engine to enable "KVM over IP" (Keyboard, Video, Mouse over Internet Protocol).
: Includes an option for Error-Correction Code (ECC) to enhance reliability. Aspeed Ast2500 Datasheet
Unlike a traditional consumer GPU, the integrated 2D VGA engine is built to drive a physical server rack console. It also powers the compressed virtual display engine for remote administrators. AST2500 - ASPEED Technology
: Utilizes SPI flash memory for firmware storage. Package : 456-pin TFBGA package, measuring 19mm x 19mm. Graphics and Remote Management (iKVM) A primary function of the
The 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. | Machine | Application | |---|---| | ast2500-evb
