The USBMOD2 is a low-cost integrated module for transferring data to / from a peripheral and a host P.C at up to 8 Million bit (1 Megabyte) per second. Based on the FTDI FT8U245 USB FIFO ­ Fast Parallel Data Transfer IC, it's simple FIFO-like design makes it easy to interface to an CPU (MCU) either by mapping the device into the memory / I/O map of the PCU, using DMA or controlling the device via IO ports.
