Vinculum-II Embedded Dual USB Host Controller IC
Version 1.5
Document No.: FT_000138 Clearance No.: FTDI# 143
4 Function Description
VNC2 is the second of FTDIs Vinculum family of Embedded USB host controller integrated circuit devices.
VNC2 can encapsulate certain USB device classes by handling the USB Host Interface and data transfer
functions using the in-built EMCU and embedded Flash memory. When interfacing to mass storage
devices, such as USB Flash drives, VNC2 transparently handles the FAT file structure using a simple to
implement command set. VNC2 provides a cost effective solution for introducing USB host capability into
products that previously did not have the hardware resources to do so.
VNC2 has an associated software development tool suite to allow users to create customised firmware.
4.1 Key Features
VNC2 is a programmable SoC device with a powerful embedded microprocessor core and dual USB
interfaces, large RAM and Flash capacity and the ability to develop and customise firmware using the
VNC2 Toolchain. VNC2 has an enhanced feature list over and above VNC1L, however the 48 pin LQFP
package is backward compatible with the VNC1L.
4.2 Functional Block Descriptions
The following paragraphs describe each function within VNC2. Please refer to the block diagram shown in
4.2.1 Embedded CPU
The processor core is based on FTDIs proprietary 16-bit embedded MCU architecture. The EMCU has a
Harvard architecture with separate code and data space.
4.2.2 Flash Module
VNC2 has 256k bytes (128k x 16-bits) of embedded Flash (E-FLASH) memory. No special programming
voltages are necessary for programming the onboard E-FLASH as these are provided internally on-chip.
4.2.3 Flash Programming Module
The purpose of the flash programmer module is to perform all necessary operations for programming the
flash, from general usage to first power on sequencing. This block is responsible for handling device
firmware upgrades which can be accessed by the debugger interface, a USB cable or Flash drive
interface.
