FT240X – Full Speed USB to 8- bit FIFO
This USB2.0 Full Speed IC offers a compact bridge to 8 bit wide FIFO interfaces. The device is a FIFO, capable of operating up to 1 MByte/s, with low power consumption (8mA). The FT240X includes the complete FT-X series feature set and enables USB to be added into a system design quickly and easily over a 8 bit wide FIFO interface
Key Hardware Features
- Entire USB protocol handled on the chip. No USB specific firmware programming required.
- Fully integrated 2048 byte MTP Memory for 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 to 1 MByte/s
- 512 byte receive buffer and 512 byte transmit buffer utilizing 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 pins.
- Transmit and receive LED drive signals.
- Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.
- 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.
- Device supplied pre-programmed with unique USB serial number.
- Supports bus powered, self powered and high-power bus powered USB configurations.
- Integrated +3.3V level converter for USB I/O.
