Pinout
The IT5570E-128 is a 128-pin LQFP (Low-Profile Quad Flat Package) embedded controller IC, commonly used in laptop EC (Embedded Controller) applications.
Key Functions:
- Manages system power sequencing, keyboard/mouse interfaces, and battery charging.
- Interfaces with the host CPU via LPC (Low Pin Count) or eSPI bus.
- Supports GPIOs, PWM, ADC, and fan control.
- Includes built-in flash memory for firmware storage.
Pin Functions (Selected):
- VCC/GND: Power supply and ground pins.
- LPC/eSPI: Host communication interface.
- GPIOs: General-purpose I/O for peripheral control.
- PWM/ADC: For fan speed and sensor monitoring.
- KB/MS: Keyboard and mouse matrix connections.
For a full pinout, refer to the IT5570E datasheet.
