VNC2-32Q

Datasheet Vinculum-II Embedded Dual USB Host Controller IC Version 1.8 Document No.: FT_000138 Clearance No.: FTDI# 143 Future Technology Devices International Ltd Vinculum-II Embedded Dual USB Host Controller IC Vinculum-II is FTDI’s 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. VNC2 has the following advanced features:  Embedded processor core  16 bit Harvard architecture  Two full-speed or low-speed USB 2.0 interfaces capable of host or slave functions  256kbytes on-chip E-Flash Memory (128k x 16-bits)  16kbytes on-chip Data RAM (4k x 32bits  Programmable UART up to 6Mbaud  Two SPI (Serial Peripheral) slave interfaces and one SPI master interface  Reduced power modes capability  Variable instruction length  Native support for 8, 16 and 32 bit data types  Eight bit wide FIFO Interface  Firmware upgrades via UART, SPI, and FIFO interface  12MHz oscillator using external crystal  General-purpose timers  +3.3V single supply operation with 5V safe inputs  Software development suite of ...
