Product Information

IT8764E-I: Super I/O with Low Pin Count Interface or eSPI Interface (LQFP 48)

The IT8764E-I is a highly integrated Super I/O using the Low Pin Count interface or eSPI interface. It provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, including H/W Monitor and Fan Speed Controller. The device's LPC and eSPI interfaces comply with Intel "LPC Interface Specification Rev. 1.1" and "eSPI specification V 1.0".


Integrated in the IT8764E-I are five logical devices, which can be individually enabled or disabled via software configuration registers, and four 16C550 standard compatible enhanced UARTs perofrmacing asynchronous communication. The devices also provide GPIO port controlling up to 24 GPIO pins.


The IT8764E-I utilizes power-saving circuitry to reduce power consumption, and once a logical device is disabled, the inputs are inhibited with the clock disabled and the outputs are tri-stated. The device operates with +3.3V power supply. The IT8764E-I is available in 48-pin LQFP.
