Produktbeskrivning
The VNC1L is a single chip embedded dual USB host controller with the following advanced features:
Two independent USB 2.0 Low-speed/Fullspeed 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 highpower 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.
