FTDI Chip Specialized ICs - FT245BL FT245BL

The FT245BL is a lead-free USB FIFO integrated circuit designed for bi-directional data transfer between a peripheral and a host PC. It supports data transfer rates of up to 1 Megabyte per second using D2XX drivers and 300 Kilobytes per second with VCP drivers. The device features a 384-byte transmit buffer and a 128-byte receive buffer, facilitating high data throughput. It includes an integrated level converter for compatibility with both 5V and 3.3V logic levels, as well as an integrated 3.3V regulator for USB I/O. The FT245BL simplifies interfacing with microcontrollers, PLDs, and FPGAs through a 4-wire handshake interface, eliminating the need for USB-specific firmware programming. It supports USB 1.1 and USB 2.0 standards and is compatible with various operating systems, including Windows, macOS, and Linux. Additional features include programmable FIFO timeout, support for USB suspend/resume, and a new Bit-Bang mode that allows the data bus to function as a general-purpose I/O port. This device is suitable for applications such as upgrading legacy peripherals to USB, USB instrumentation, industrial control, and various USB data transfer needs. Its compact 32-LQFP package and RoHS compliance make it a viable option for engineers looking to integrate USB functionality into their designs.
