Intel(R) 7 Series/C216 Chipset Family SMBus Host Controller - 1E22 Driver

The Intel(R) 7 Series/C216 Chipset Family SMBus Host Controller – 1E22 driver helps Windows identify the chipset’s System Management Bus controller, which supports low-speed communication with compatible motherboard components. It is relevant when reinstalling Windows, resolving an unrecognized SMBus controller in Device Manager, or restoring chipset device identification after a system recovery.

Key Features

• SMBus controller recognition: Helps Windows correctly identify the Intel 7 Series/C216 SMBus host controller rather than displaying it as an unknown device.
• Chipset configuration support: Provides device information Windows uses to associate the controller with the appropriate system components. Some chipset packages primarily supply INF identification files rather than a standalone functional driver.
• Legacy Windows coverage: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Compatibility depends on the individual package and your system’s architecture.
• Hardware-specific matching: The controller is typically identified by PCI hardware ID `PCIVEN_8086&DEV_1E22`, which helps distinguish it from other chipset devices.

How to Install Intel(R) 7 Series/C216 Chipset Family SMBus Host Controller – 1E22 Driver

1. Confirm the device. Open Device Manager and locate the SMBus controller, often under Other devices or System devices. Open Properties, select Details, and check Hardware Ids for `VEN_8086&DEV_1E22`.
2. Check package compatibility. Before choosing an Intel(R) 7 Series/C216 Chipset Family SMBus Host Controller – 1E22 driver download for Windows, confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 11 is not among the listed supported operating systems.
3. Verify the source and provider. Although this listing names Synaptics as the vendor, the controller is Intel hardware. Confirm that the package explicitly supports your controller and computer model; prefer your PC manufacturer’s or Intel’s official resources when available. A free download alone does not establish authenticity.
4. Install the compatible package. Extract the downloaded archive if necessary, then run the included installer. For an INF-based package, use Device Manager’s Update driver option and browse to the extracted folder.
5. Restart and verify. Restart if prompted, then check Device Manager for correct identification and any remaining warning icons.

When considering an update, choose the latest version explicitly compatible with your hardware and operating system—not simply the newest package available. If the controller already works correctly, review the release notes before changing drivers; an update does not automatically improve performance.
