The VDIP1 is a MCU to embedded USB host controller development module for the VNC1L IC device. The Vinculum VNC1L is the first of Vinculum family of embedded USB host controller integrated circuit devices. Not only is it able to handle the USB host interface and data transfer functions but owing to the inbuilt MCU and embedded flash memory, Vinculum can encapsulate the USB device classes as well. The VDIP1 module is targeted for MCU to USB host / slave interface applications. This module is supplied on a PCB designed to fit into a 24 pin DIP socket and provides access to the UART, parallel FIFO and SPI interface pins on the VNC1L device, via its AD and AC bus pins.
