FT234XD USB TO BASIC UART IC Version 1.2 Document No.: FT 000753 Clearance No.: FTDI 324 Future Technology Devices International Ltd. FT234XD (USB to BASIC UART IC) USB Battery Charging Detection. Allows for USB The FT234XD is a USB to serial UART peripheral devices to detect the presence of a interface with optimised packaging (3mm higher power source to enable improved x 3mm 12 pin DFN) for smaller PCB charging. designs and the following advanced Device supplied pre-programmed with unique USB serial number. features: USB Power Configurations supports bus- powered, Single chip USB to asynchronous serial data self-powered and bus-powered with power switching transfer interface. Integrated +3.3V level converter for USB I/O. Entire USB protocol handled on the chip. No USB specific firmware programming required. True 3.3V CMOS drive output and TTL input Fully integrated 2048 byte multi-time- Operates down to 1V8 with external pull ups. programmable (MTP) memory, storing device Tolerant of 5V input. descriptors and CBUS I/O configuration. Fully integrated clock generation with no external Configurable I/O pin output drive strength crystal required plus optional clock output selection 4 mA (min) and 16 mA (max). enabling a glue-less interface to external MCU or Integrated power-on-reset circuit. FPGA. Fully integrated AVCC supply filtering - no Data transfer rates from 300 baud to 3 Mbaud external filtering required. (RS422, RS485, and RS232) at TTL levels. UART signal inversion option. 512 byte receive buffer and 512 byte transmit buffer utilising buffer smoothing technology to + 5V Single Supply Operation. allow for high data throughput. Internal 3.3V/1.8V LDO regulators FTDIs royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement Low operating and USB suspend current for USB driver development in most cases. 8mA (active-typ) and 70uA (suspend-typ). Configurable CBUS I/O pin. UHCI/OHCI/EHCI host controller compatible. Transmit and receive LED drive signals. USB 2.0 Full Speed compatible. UART interface support for 7 or 8 data bits, 1 or 2 Extended operating temperature range -40 to stop bits and odd / even / mark / space / no parity 85 C. Synchronous and asynchronous bit bang interface Available in compact Pb-free 12 pin DFN package options with RD and WR strobes. (3mm x 3mm) RoHS compliant.
