FT201XQ-R

Controllers Overview

The FT201XQ-R is a USB to I2C bridge controller manufactured by FTDI. It implements the USB 2.0 Full Speed standard with a data rate of 12 Mb/s. The device operates within a supply voltage range of 2.97 V to 5.5 V, typically at 5 V, and draws 8 mA during operation. It is housed in a QFN-16 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Controllers Feature Summary

• Provides a dedicated bridge interface converting USB protocols to I2C communication.
• Integrates complete USB protocol handling without requiring external firmware programming.
• Supports battery charger detection for enhanced power management capabilities.

Controllers Applications

• USB to I2C converter modules
• Interfacing microcontrollers or PLDs with I2C peripherals via USB
• Adding USB connectivity to legacy I2C-based systems

Controllers Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the QFN-16 footprint and thermal requirements for the specified operating temperature range.

Controllers Selection Notes

Select this component specifically for applications requiring USB to I2C translation rather than UART or SPI interfaces. Consider the 12 Mb/s full-speed limitation against higher bandwidth requirements. Evaluate the QFN-16 package suitability for the target PCB layout and assembly processes compared to other pin counts in the series.

Controllers Part Context

This part belongs to the FT201 series of USB interface ICs designed for serial protocol bridging. It shares the X-CHIP branding and CMOS process technology common to FTDI's compact interface solutions. The device complements the broader FT-X family by addressing specific I2C connectivity needs in embedded designs.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative vendors, as pinouts and electrical characteristics may differ significantly across manufacturers.
