Embedded USB Host
Controller IC
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
enhances 32 bit arithmetic speeds.
(NCP)
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.
