Product Introduction
The FT234XD is a USB to serial UART interface with optimised packaging (3mm x 3mm 12 pin DFN) for smaller PCB designs.
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 multi - time programmable (MTP) memory, storing device descriptors and CBUS I/O configuration.
- Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue - less interface to external MCU or FPGA.
- Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, and RS232) at TTL levels.
- 512 byte receive buffer and 512 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
- 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.
- Transmit and receive LED drive signals.
- UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity.
- Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.
- USB Battery Charging Detection. Allows for USB peripheral devices to detect the presence of a higher power source to enable improved charging.
- True 3.3V CMOS drive output and TTL input; Operates down to 1V8 with external pull ups.
- Tolerant of 5V input.
- UART signal inversion option.
- Internal 3.3V/1.8V LDO regulators.
- Low operating and USB suspend current; 8mA (active - typ) and 70uA (suspend - typ).
- UHCI/OHCI/EHCI host controller compatible.
- USB 2.0 Full Speed compatible.
Applications
- - USB to RS232/RS422/RS485 Converters - Upgrading Legacy Peripherals to USB - Utilising USB to add system modularity - Incorporate USB interface to enable PC transfers for development system communication - Cellular and Cordless Phone USB data transfer cables and interfaces - Interfacing MCU/PLD/FPGA based designs to add USB connectivity - USB Audio and Low Bandwidth Video data transfer - USB Smart Card Readers - USB Instrumentation - USB Industrial Control - USB FLASH Card Reader and Writers - Set Top Box PC - USB interface - USB Wireless Modems - USB Bar Code Readers - USB dongle implementations for Software/Hardware Encryption and Wireless Modules - Detection of dedicated charging port for battery charging at higher supply currents.
