FTDI FT232RNL USB to UART Interface Bridge IC 28-Pin SSOP

The FTDI FT232RNL-REEL is a highly integrated, single-chip solution for USB full-speed to serial UART interfacing. This advanced IC simplifies USB to serial designs by incorporating essential components directly on the device, including an internal oscillator, USB termination resistors, and an EEPROM. It handles the entire USB protocol onboard, eliminating the need for complex USB-specific firmware programming, making it an ideal choice for straightforward integration and rapid development.

This interface bridge supports versatile voltage requirements with an I/O voltage range from 1.8V to 5V and operates from a supply voltage of 3.3V to 5.25V. It delivers robust data transfer with speeds of up to 3MBaud and supports full-speed (12Mbps) USB communication. For effective data flow control, it offers fully assisted hardware handshaking or X-On/X-Off software handshaking, along with in-built support for event characters and line break conditions.
