FT245BL General Description
The FT245BL provides an easy cost-effective method of transferring data to / from a peripheral and a host P.C. at up to 8 Million bits (1 Megabyte) per second. Its simple, FIFO-like design makes it easy to interface to any microcontroller or microprocessor via IO ports.
To send data from the peripheral to the host computer, simply write the byte-wide data into the module when TXE# is low. If the (384-byte) transmit buffer fills up or is busy storing the previously written byte, the device keeps TXE# high in order to stop further data from being written until some of the FIFO data has been transferred over USB to the host. TXE# goes high after every byte written.
When the host sends data to the peripheral over USB, the device will take RXF# low to let the peripheral know that at least one byte of data is available. The peripheral can read a data byte every time RXF# goes low. RXF# goes high after every byte read.
By using FTDI's virtual COM port drivers, the peripheral looks like a standard COM port to the application software. Commands to set the baud rate are ignored - the device always transfers data at its fastest rate regardless of the application's baud-rate setting. Alternatively, FTDI's D2XX drivers allow application software to access the device "directly" through a published DLL based API. Details of the current VCP and D2XX driver can be found on FTDI's web site ( http://www.ftdichip.com )
