The "new" AST2500 datasheet is interesting because it frequently references the AST2600. Here is how the chips differ according to the latest comparative tables:
A major headache in older designs was bus contention on I2C channels 0 and 1. The new datasheet introduces a "bus park" mode register (0xE000_01C4) that prevents the BMC from locking the bus during host reset cycles. aspeed ast2500 datasheet new

Why do engineers hunt for a new datasheet of an old chip? Because ASPEED often publishes critical implementation details months after the chip launches. Here are the top three hidden gems found only in the latest AST2500 literature: Introduction: The Quiet Giant of Server Management Why
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.
