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

(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).
