TUSB2E112YCGR

Overview

The TUSB2E112YCGR is a USB 2.0 to eUSB2 repeater supporting host and device modes with LS, FS, and HS signaling. It operates on a 3.3V supply (3.0–3.6V) and an analog supply of 1.8V (1.62–1.98V). The I/O voltage for the I2C interface and GPIOs is fixed at 1.2V. It supports up to 20Ω channel ESR via strap pins or I2C configuration. The device features auto-resume ECR, L2 interrupt resume, BC 1.2 support, and CTA-936 UART mode. It is housed in a 15-pin DSBGA package.

Feature Summary

• Supports dual-role device operation for both host and peripheral modes
• Provides configurable high-speed channel compensation for trace loss
• Includes integrated battery charging detection and advertising capabilities
• Offers debug and manufacturing test access through I2C and GPIO interfaces

Applications

• Notebooks and desktops
• Cell phones
• Tablets
• Wearables
• Portable electronics

Procurement Notes

Verify the specific B1 device variant marking matches the required 1.2V I/O voltage level. Confirm that the system design accommodates the 15-pin DSBGA package dimensions. Ensure the I2C pull-up voltage aligns with the 1.2V specification for this part number. Check for any recent documentation updates regarding pin configurations.

Selection Notes

Select this variant when a 1.2V I/O interface is required for the eUSB2 PHY connection. The B1 version includes low-power features like auto-resume ECR not available in the B0 version. Consider the 1.2V constraint for all connected GPIOs and I2C lines. Verify compatibility with the target eUSB2 signal levels before implementation.

Part Context

This component belongs to the TUSB2E11 family of USB-to-eUSB2 repeaters. The TUSB2E112YCGR specifically denotes the B1 silicon revision with a 1.2V I/O voltage capability. It differs from the TUSB2E111YCGR, which supports 1.8V I/O. Both variants share the same physical package and core functionality.

Replacement Considerations

TUSB2E111YCGR: Supports 1.8V I/O instead of 1.2V; verify voltage compatibility.
