FT234XD
FT234XD is USB to BASIC UART manufactured by FTDI.
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 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.
Device supplied pre-programmed with unique USB serial number.
