[VNC1L-1A] USB Host Controller

VNC1L-1A는 USB Host Controller와 MCU가 포함된 칩으로 대분의 특정 펌웨어가 ROM파일 형태로 제공되 쉽게 USB Host Controller를 제어할 수 있도록 한 FTDI(http://www.vinculum.com/index.html) 칩이다.
FDI의 USB2Seral, USB2FIFO, USB2SPI 기능을 제공하여 USB메모리 스틱이나 외장 하드등의 MassStorage장치를 시리얼 이나 SPI등으로 제어할 수 있다.
쉽고 간단하게 USB Host를 구성할 수 있어 소량의 응용제품을 빠르게 개발해야 할 경우 편리하게 사용할 수 있을것 같다.

Introducing the Vinculum VNC1L USB Host Controller

FTDI VNC1L
USB Host Controller IC

The initial product member of the family is the VNC1L device which features two USB Ports which can be individually configured by firmware as Host or Slave ports.

Connect USB Flash drives to MCUs via the Vinculum's UART, SPI or parallel FIFO interfaces. Connect USB device classes including Mass Storage Class, Printer Class and HID Class devices, or even FTDI's own range of USB-UART and USB-FIFO ICs to an embedded system.

Key VNC1L features include:

? 8/32 bit V-MCU Core
? Dual DMA controllers for hardware acceleration
? 64k Embedded Flash Program Memory
? 4k internal Data SRAM
? 2 x USB 2.0 Slow/Full speed Host/Slave Ports
? UART, SPI and Parallel FIFO interfaces
? PS2 legacy Keyboard and Mouse Interfaces
? Up to 28 GPIO pins depending on configuration
? 3.3V operation with 5V safe inputs
? Low power operation (25mA running/2mA standby)
? FTDI firmware easily updated in the field
? LQFP-48 RoHS compliant package
? Multi-processor configuration capable

The Vinculum Firmware User Manual can be found on the Documents page.
This includes explanations of the application and capabilities of each build of firmware. VDAP Firmware is installed on all new VDRIVE and VDIP modules by default and will typically be the version applicable to most applications. VMUSIC modules require VMSC1 Firmware. To utilise VDPS Firmware external hardware is required for VDIP modules.
