VNC2 controller

Future Technology Devices International (FTDI) has introduced a user programmable dual USB 2.0 host/slave intelligent SoC controller.

The Vinculum VNC2 includes a 16bit MCU core, 256Kbyte on-chip programmable e-flash program memory and 16Kbyte of SRAM data memory. The I/O communication capability has been enhanced to include two SPI slave controllers, an SPI master controller, high-speed UART interface (up to 3M baud ) plus a flexible eight-channel PWM block, allowing precise 16bit control of motors, servos and other analog applications. VNC2's 1-Pin debugger interface functions independently of the MCU core.

VNC2 is offered in three different pin-count sizes32LD, 48LD and 64LDsupporting up to 44 user-defined IO pins. Each pin-count size is available in LQFP or QFN package options.

Operating from a single +3.3Vdc supply, the VNC2 has a low standby current of typically 128?A and has three low-power modes.

Applications including camera, mobile accessories, data loggers, toys, keyboards, game controller interfacing, point-of-sale applications and USB to USB bridges.

VNC2 comes with a royalty-free software development environment, which includes a compiler, linker and debugger. The Integrated Design Environment is based on 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.

For 10,000+ quantities, the VNC2 48-pin LQFP is priced at $2.75. Engineering samples are now available with mass production expected from May 2010.
