Host controller handles USB data transfers to boost processing power

VNC2 includes a 16-bit MCU core, 256kB on chip programmable e-Flash program memory and 16kB 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 8 channel PWM block, allowing precise 16-bit 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 sizes—32LD, 48LD and 64LD—supporting up to 44 user defined IO pins. Each pin-count size is available in LQFP or QFN package options.

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

Applications including camera, mobile accessories, data loggers, toys, keyboards, game controller interfacing, POS 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 (IDE) 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.

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