FT311D-32L1C-T

Controllers Overview

The FT311D-32L1C-T is a USB interface integrated circuit manufactured by Future Technology Devices International Ltd. It functions as a full-speed USB host controller designed for Android Open Accessory mode connectivity. The device bridges the USB port to user-selectable interfaces including GPIO, UART, PWM, I2C master, SPI master, and SPI slave. It operates within a supply voltage range of 2.97V to 3.63V and supports data rates up to 1 Mb/s. The component is housed in a 32-pin LQFP package with dimensions of 7x7 mm and is rated for an operating temperature range of -40°C to +85°C.

Controllers Feature Summary

• Supports Android Open Accessory protocol for peripheral hardware access
• Bridges USB to multiple user-configurable interface types
• Integrated ESD protection mechanisms

Controllers Applications

• Development of USB accessories connecting to Android platforms
• Providing access to peripheral hardware from Android devices via USB device ports
• Full-speed USB host implementations requiring GPIO or serial interface expansion

Controllers Procurement Notes

Verify the specific suffix 'T' against official FTDI documentation to confirm tray packaging status, as distributor listings may vary. Ensure compatibility with the target Android platform's hardware requirements before procurement. Cross-reference the 32-LQFP package dimensions for PCB layout accuracy.

Controllers Selection Notes

Select this component when designing embedded systems that require a dedicated USB host controller for Android devices. It is suitable for applications needing flexible interface conversion without complex microcontroller programming. Consider the 32-pin LQFP form factor for surface-mount assembly constraints.

Controllers Part Context

This part belongs to the FT311D series of USB interface ICs from FTDI. It is closely related to the FT312D series, which offers high-speed capabilities. The UMFT311EV evaluation module utilizes this IC family for development purposes. It serves as a specialized solution for Android accessory development rather than general-purpose USB-to-serial conversion.

Controllers Replacement Considerations

The FT311D-32L1C-R is a reel-packaged alternative within the same functional family. The FT312D series provides high-speed USB alternatives but requires design adjustments for speed differences.
