FT230X - Single chip USB2.0 to basic UART interface IC

This USB2.0 Full Speed  IC offers a compact bridge to basic UART interfaces, with low power consumption (8mA), and is capable of operating up to 3MBaud. It includes the complete FT-X series feature set, enabling USB to be added into a system design quickly and easily over a UART interface.

Key features:

  • Single chip USB to asynchronous serial data transfer interface.
  • Entire USB protocol handled on the chip. No USB specific firmware programming required.
  • Fully integrated 2048 byte EEPROM for storing device descriptors and CBUS I/O configuration.
  • Data transfer rates from 300Baud to 3MBaud
  • FTDI's royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
  • Configurable CBUS I/O pin.
  • Device supplied pre-programmed with unique USB serial number.
  • Supports bus powered, self powered and high-power bus powered USB configurations.
  • Battery Charger Detection. May be used by mobile devices to detect the presence of a charger on the USB port to enable higher current / faster charging of batteries.
  • Low operating current of 8mA (typical) and USB suspend current of 125uA (typical) current.
  • Low USB bandwidth consumption.
  • UHCI/OHCI/EHCI host controller compatible.
  • USB 2.0 Full Speed compatible.
  • 16 Pin SSOP and QFN packages (both RoHS compliant).
