The AST2500 has 16 ADC channels. The older datasheet offered ±5°C accuracy. The new calibration guide (bundled with the datasheet) provides a two-point calibration formula (30°C and 80°C) to achieve ±1.5°C accuracy for the internal thermal sensor.

The BMC allows administrators to remotely power cycle, monitor, and configure servers even when the host operating system is powered down or entirely unresponsive.

ASPEED AST2500 represents a significant milestone in the evolution of Baseboard Management Controllers (BMCs), serving as the sixth generation of server management processors from ASPEED Technology

The updated AST2500 datasheet details a highly compact physical footprint designed to fit standard server PCB spacing constraints. Packaging Details LFBGA (Low-profile Fine-pitch Ball Grid Array) Ball Count: 416-ball package Dimensions: 19mm x 19mm with a 0.8mm ball pitch. Voltage Domains

: Its built-in security features help protect against unauthorized access and ensure that management operations are securely performed.

Typically requires a minimum of 32MB to 64MB SPI NOR flash memory. AMI MegaRAC Structure: Proprietary commercial firmware stack.
