FTDI VNC1L Embedded USB Host Controller Development Module (VDIP1)

The FTDI VNC1L Embedded USB Host Controller Development Module (VDIP1) is a development module built around the FTDI Vinculum VNC1L IC, designed for rapid prototyping and development of embedded USB host applications.

Overview

The VNC1L IC integrates an MCU and embedded flash memory, enabling the module to handle USB host interfaces, data transfer, and USB device class encapsulation within a single device. The module is supplied on a PCB that fits into a standard 24-pin DIP socket, allowing straightforward integration into existing designs.

Interfaces and Connectivity

• Access to the VNC1L UART (serial), parallel FIFO, and SPI interfaces via the bus pins
• Jumper selectable configuration for switching between UART, parallel FIFO, or SPI interfaces
• One USB 'A' type socket for connecting peripheral devices
• A second USB port available via module pins where required

The module supports flexible communication with external microcontrollers and can be adapted to various host systems through jumper selection.

Power and Status

• Powered directly from a 5V USB connection, with no external power supply required
• Auxiliary 3.3V/200mA output for powering external logic circuits
• Power and traffic LEDs for visual status indication
• PROG# and RESET# control pins brought out to the jumper interface for firmware programming and updates via USB flash disk or the supported interfaces

Specifications

• Dimensions: 43 mm x 33 mm x 15 mm
• Weight: 100 g

The compact form factor and light weight make the module suitable for bench testing and embedded projects, supporting quick validation of USB host controller designs before final integration.
