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 32-
bits
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
