Introduction The IT8995E-128 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

| Pin | Signal | Description | |------|--------|-------------| | 1 | LCLK | 33 MHz clock from PCH | | 2 | LFRAME# | Frame signal for cycle start/end | | 3 | LRST# | LPC reset (active low) | | 4 | LAD0 | Multiplexed address/data line 0 | | 5 | LAD1 | Multiplexed address/data line 1 | | 6 | LAD2 | Multiplexed address/data line 2 | | 7 | LAD3 | Multiplexed address/data line 3 | | 8 | LDRQ# | DMA request line | | 9–12 | GND | Digital ground | Most pins on the IT8995E-128 are multi-function. The datasheet defines a register map to select between GPIO, UART, fan control, or ADC input. | Symbol | Parameter | Min | Max
