2.2 Functional Block Descriptions  
USB Host / Slave Transceivers 1 and 2 - The two USB transceiver cells provide the USB host / slave physical USB  
1.1 / USB 2.0 full-speed device interface. On each the output drivers provide 3.3V level slew rate control signalling,  
whilst a differential receiver and two single ended receivers provide USB data in, SEO and USB Reset condition  
detection. These cells also incorporate internal USB pull-up or pull down resistors as required for host or slave mode.  
USB Host / Slave Serial Interface Engine ( SIE ) - These blocks handle the parallel to serial and serial to parallel  
conversion of the USB Physical layer including bit sufng / unstufng, CRC generation / checking, USB frame  
generation and error checking.  
12 MHz Oscillator - The 12MHz Oscillator cell generates a 12MHz reference clock input to the Clock Multiplier PLL  
from an exteral 12MHz crystal.  
Clock Multiplier PLL - The Clock Multiplier PLL takes the 12MHz input from the Oscillator Cell and generates 24MHz  
and 48MHz reference clock signals, which is used by the USB SIE Blocks, the MCU core, System Timer and UART  
Prescaler blocks.  
Program and Test Logic - this block provides a means of programming the onboard E-Flash memory. When PROG#  
is pulled low and the device is reset, the onboard E-Flash memory is bypassed by an internal hard coded BootStrap  
Loader ROM which contains code to allow the E-Flash memory to be programmed via commands to the UART  
interface. FTDI provides a software utility which allows the VNC1L to be programmed using this method. The TEST  
pin is used in manufacturing to enhance the testability of the various internal blocks and should be tied to GND.  
DMA Controller 1 and 2 - The twin DMA controllers in the VNC1L greatly enhance performance by allowing data  
from the two USB SIE controllers, UART, FIFO and SPI to be transferred between each other via the data SRAM with  
minimal MCU intervention.  
Data SRAM - This 4k x 8bit block acts as the data ( variable ) memory for the Vinculum MCU, though it can also be  
accessed transparently to the MCU by the twin DMA controllers.  
NPU ( Numeric CoProcessor ) - Most Vinclum MCU operations are 8-bit, however there are some scenarios such as  
transversing disk FAT tables which involve extensive 32 bit arithmetic. In order to speed up these operations, the MCU  
has a dedicated 32 bit co-processor block.  
UART Prescaler - this block provides the master transmit / receive clock for the UART block. By varying the prescalar  
value, the baud rate of the UART can be adjusted over a range of 300 baud to 1M baud.  
SYSTEM TIMER - The system timer provides a regular interrupt to the Vinculum MCU, typically at 1mS intervals. This  
is used by the MCU to provide timeouts and other timing functions.  
VINCULUM MCU CORE - The “heart” of the VNC1L is the VMCU core based on FTDI’s proprietary 8-bit embedded  
MCU ( EMCU ) architectiure. VMCU has a Harvard architecture i.e. separate code and data space and supports  
64k byes of program code, 64k byes of ( paged ) data space and 256 bytes of IO space. It uses “enhanced CISC”  
technology - typically VNCU instructions would replace several lines of code in conventional CISC or RISC processors  
giving RISC like performance in a CISC architecture with the advantage over both of excellent code compression in  
the program ROM space.  
E-FLASH Program ROM - The VNCL1L has 64k bytes 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.  
Common methods of programming the E-FLASH ( both under control of the VMCU ) are via the UART by pulling the  
PROG# pin low and resetting the device OR by using the programming via a USB FLASH drive feature provided in  
many of the VNC1L rmware packages.  
BOOTSTRAP LOADER ROM - This is a small block of hard encoded ROM ( 512 x 8 bits ) whivh bypasses the main  
e_FLASH memory when PROG# is pulled low. This provides a means of programming the entire E-Flash memory via  
the UART interface.  
UART and FIFO Logic - These provide optional serial and parallel interfaces to the VNC1L equivalent to the  
interfaces on FTDI’s FT232 and FT245 USB UART and FIFO products.  
GPIO Blocks - general purpose IO pins. See the tables below to determine which are available for any specic  
conguration.
