The IT8995E 128 is not a "dumb" I/O chip; it executes internal ROM/RAM code. The datasheet details:
The is a highly integrated Super I/O (Input/Output) controller manufactured by ITE (Integrated Technology Express, Inc.). This chip is a cornerstone of modern motherboard design, particularly for industrial PCs, embedded systems, and high-end consumer laptops. Unlike basic I/O controllers, the IT8995E-128 bridges legacy interfaces (PS/2, LPC, UART) with advanced system management features. it8995e 128 datasheet
In motherboard schematics, you might see variations like or CXS . Generally, these revisions are cross-compatible during repairs. The chip also includes modern safety standards like RoHS compliance , built-in electrostatic discharge (ESD) protection , and overheating safeguards to ensure a long product lifecycle.
