Copyright 2011 Future Technology Devices International Limited Datasheet Vinco Touch-Key Shield Version Document No. FT_000514 Clearance No. FTDI#242 1 Introduction The Vinco Touch-Key is a shield that mates with the FTDI Vinco development module to allow touch pad operation. The shield includes an STMPE821 device, which is an 8-channel GPIO capacitive touch-key sensor. The sensor communicates to the Vinculum-II VNC2 on the Vinco module via I2C protocol. Vinco is a development module inspired by the Arduino concept and uses the Vinculum-II VNC2 dual port USB Host/device IC. Vinco uses a VNC2-64Q package to facilitate 38 GPIO options on pitch sockets. Vinco is designed as a prototyping platform for VNC2 based designs and applications. Software libraries for I2C are available with the free with the free VNC2 IDE. Figure VINCO Development Module and the Touch-Key Shield VNC2 VNC2 is the second of FTDI’s Vinculum family of embedded dual USB host controller devices. The VNC2 device provides USB host interfacing capability for a variety of different USB device classes including support for BOMS bulk only mass storage , Printer and HID human interface devices . For mass storage devices such as USB Flash drives, VNC2 transparently handles the FAT file structure. Communication with non USB devices, such as a low cost microcontroller, is accomplished via either UART, SPI or parallel FIFO interfaces. VNC2 provides a new, cost effective solution for providing USB Host capability into products that previously did not have the hardware resources available. VNC2 allows customers to develop their own firmware using the Vinculum II software development tool suite. These development tools provide compiler, assembler, linker and debugger tools complete within an integrated development environment IDE . The Vinculum-II VNC2 family of devices are available in Pb-free RoHS compliant 32-lead LQFP, 32-lead QFN, 48-lead LQFP, 48-lead QFN, 64-Lead LQFP and 64-lead QFN packages For more information on the ICs refer to VNC2.
