FTDI FT230XQ USB 2.0 to UART Converter IC, QFN-16

FTDI FT230XQ USB 2.0 to UART Converter IC delivers USB 2.0 Full Speed to UART bridging at data rates up to 3 Mbaud.

The FTDI FT230XQ is a fully integrated USB 2.0 Full Speed circuit that provides a compact and efficient bridge to basic UART (Universal Asynchronous Receiver-Transmitter) interfaces. This single-chip solution handles the entire USB protocol on-chip, eliminating the need for USB-specific firmware programming and enabling rapid integration of USB functionality into system designs.

The device supports data transfer rates from 300 baud up to 3 Mbaud, with a typical operating current of 8mA. It incorporates a fully integrated 2048-byte EEPROM for storing device descriptors and configurable CBUS I/O settings, providing flexibility for custom applications. The inclusion of 512-byte transmit and receive buffers, utilising advanced buffer smoothing technology, supports high data throughput and reliable communication.

Key Features

• Integrated Design: Fully integrated clock generation with no external crystal required, plus internal 3.3V/1.8V LDO (Low-Dropout) regulators.
• Driver Support: Includes royalty-free VCP (Virtual COM Port) and Direct (D2XX) drivers, removing the need for custom USB driver development.
• Flexible I/O: Configurable CBUS I/O pins, transmit and receive LED drive signals, and configurable I/O pin output drive strength.
• UART Interface: Supports 7 or 8 data bits, 1 or 2 stop bits, and odd, even, mark, space or no parity options, with a UART signal inversion option.
• Advanced Interfaces: Synchronous and asynchronous bit-bang interface options with RD# and WR# strobes.
• Power Management: Supports bus-powered, self-powered and high-power bus-powered USB configurations, with integrated battery charger detection for faster charging when connected to a USB port.
• Level Conversion: Integrated +3.3V level converter for USB I/O.
