Programmable dual USB 2.0 host/slave SoC lowers design component count

March 03, 2010 // Julien Happich

Future Technology Devices International (FTDI) launched Vinculum VNC2, a user programmable dual USB 2.0 Host/Slave intelligent SoC controller delivered with a royalty free software development environment.

VNC2 includes a new, customised 16bit MCU core, 256kB on chip programmable e-Flash program memory and 16kB of SRAM data memory. The IO communication capability has been enhanced to include 2 SPI slave controllers, 1 SPI master controller, 1 high speed UART interface (up to 3M baud ) plus a flexible 8 channel PWM block allowing precise 16-bit control of motors, servos and other analog application areas.

In addition to these enhancements, VNC2’s 1-pin debugger interface, which functions independently of the MCU core, provides a simple yet sophisticated debugging / device programming interface. All these features come at a substantially lower cost than it predecessor VNC1.

VNC2 launches in 3 different pin-count sizes, 32LD, 48LD and 64LD supporting up to 44 user defined IO pins. Each pin-count size is available in LQFP or the more compact QFN package option, 6 variants in total. The 48LD LQFP version, offers a “close-fit” equivalent pin-out to the current VNC1L allowing easy system upgrades to the new VNC2, often with just a simple BOM change.

Operating from a single +3.3 VDC supply, the VNC2 has a low standby current of typically 128microA and also has 3 low power modes.

The Vinculum VNC2 suits a broad range of USB consumer and industrial related applications including camera, mobile accessories, data loggers, toys, keyboards, game controller interfacing, POS applications and USB to USB bridges. Engineering samples of VNC2 are now available with mass production expected from May 2010.

The IDE developed in-house, includes a compiler, linker and debugger to fully use the increased memory and multitude of communication protocols handled by VNC2. The software developed toolkit is based on the ‘C’ language and provides a comprehensive suite of object files to provide support for USB host functionality including USB Flash Drive (B.O.M.S.) storage, HID, USB COMMs class and FAT File functionality.
