Datasheet
The VNC1L is a single chip embedded ^•
dual USB host controller with the
following advanced features:
•
• Two independent USB 2.0 Low-speed/Full-
speed USB host ports.
• Individual ports can be configured as host or •
slave.
• Configurable options to interface to external
Command Monitor via either UART, FIFO or
•
SPI slave interface.
• Entire USB protocol handled on the chip.
•
• Integrated pull-up and pull-down resistors.
• Integrated FTDI proprietary, 8/32-bit
•
embedded MCU processor core -Vinculum
•
MCU (VMCU) - using “enhanced CISC”
technology.
•
• Integrated, reconfigurable, 64k bytes of
embedded Flash (E-FLASH) memory to store
firmware. 4k bytes data RAM.
•
• Field upgradeable firmware over UART or
USB.
•
• Integrated Numeric Co-Processor (NCP)
enhances 32 bit arithmetic speeds.
Twin DMA controllers (one per USB interface)
provide hardware acceleration of data transfer
from USB to external IO bus.
Operational configuration via a choice of free,
downloadable firmware – no external software
control required.
Four fully configurable data and control I/O
buses providing up to 28 pins of general
purpose I/O.
Integrated firmware allows read from and write
to FAT format USB Flash keys.
Supports bus powered, self powered and high-
power bus powered USB configurations.
Programmable via UART interface.
+3.3V single supply operation with 5V safe
inputs.
Low power operation (25mA operational, 2mA
in standby).
-40°C to +85°C extended operating
temperature range.
Available in compact Pb-free 48 Pin LQFP
package (RoHS compliant).
