FT232RL USB-to-UART Serial Interface IC

The FT232RL is a USB-to-UART serial interface IC from FTDI designed to provide a simple and reliable connection between a USB host and asynchronous serial devices. It is widely used in microcontroller development boards, USB-to-TTL adapters, embedded systems, industrial equipment, and serial communication interfaces.

The device integrates a USB 2.0 Full-Speed interface with an asynchronous serial UART, allowing a computer or other USB host to communicate with a microcontroller through a standard serial interface. It supports configurable baud rates and provides commonly used UART control signals for flexible embedded-system designs.

The FT232RL also integrates USB termination resistors, a clock multiplier, and an internal EEPROM for storing device configuration information, helping reduce the number of external components required in a USB-to-serial design.

With its compact 28-pin SSOP package and broad operating-voltage support, the FT232RL is a practical choice for adding USB connectivity and serial communication to custom electronic circuits and development projects.
