FT200XD-R
Overview
The FT200XD-R is a compact USB to I2C bridge controller designed to simplify the addition of a USB interface to system designs. It handles the entire USB protocol on-chip, requiring no USB-specific firmware programming, and provides a standard I2C slave interface for communication with microcontrollers or other peripherals. The device features an integrated clock, MTP memory for configuration, and a small 10-pin DFN footprint for space-constrained applications.
Why Choose This Part
This bridge eliminates the need for an external crystal and provides a simple I2C interface that is 5V tolerant, facilitating easy integration with various logic levels. It includes built-in battery charger detection to help systems identify the power source capacity from a USB port. The integrated MTP memory allows for easy customization of USB descriptors without an external EEPROM.
Applications
Key Specifications
Getting Started
To begin development, download the FTDI VCP or D2XX drivers which provide standard serial port emulation or direct API access. Hardware prototyping can be done using the UMFT200XD breakout module to verify I2C timing and USB enumeration. Use the FT_Prog utility for Windows to configure the internal MTP memory for custom VID/PID and string descriptors.
