Original Press Release:

Macraigor Systems Demonstrates New USB 2.0 JTAG Interface Devices at Embedded Systems Conference

SAN JOSE, CA-April 3, 2006-Macraigor Systems LLC today announced usb2Demon and usb2Sprite, two new USB 2.0 JTAG debug interface devices being demonstrated at the Embedded Systems Conference in Booth 1935. These new devices are immediately available for ARM, Xscale and PowerPC processors. The usb2Demon and usb2Sprite devices are identical in functionality, but differ in speed to provide embedded developers with flexibility in choosing an appropriate price/performance ratio for their projects.

usb2Demon is the high-speed version of the product. With pricing set at $750 USD, this device matches the price of Macraigor's popular Raven parallel JTAG interface while providing a significant download speed improvement (see table below for sample download speed comparisons). usb2Sprite is a low-cost, slower version of the device for price-sensitive projects or situations where maximum download speed is not an issue. Pricing for usb2Sprite has been set at $210 USD.

Both new devices support Windows and Linux hosts and are fully compatible with all of Macraigor's software tools, including the Flash Programmer, J-Scan suite of JTAG hardware debug tools and the free, low-level OCD Commander debugger and pre-built GNU tools suite.
