Introduction

Vinculum-II is 2nd generation of USB Host device. The CPU has been upgraded from the previous VNC1L device, dramatically increasing the processing power. The IC architecture has been designed to take care of most of the general USB data transfers, thus freeing up processing power for user applications. Flash and RAM memory have been increased providing larger user areas of memory for the designer to incorporate his own code. The designers also have the ability to create their own firmware using the new suite of software development tools.
