USB to I2C-Bus Adapter is USB-powered.
Press Release Summary:
Model UCA93LV supports all I2C-Bus-compliant protocols, including Master and Slave in 8- and 10-bit/extended addressing formats in both 100 and 400 kHz high-speed modes. Product offers full data-logging mode and real-time data filtering and works with I2C-Bus systems running on supplies from 1.8-5 V. I2C-Bus voltage selection is software programmable. In addition to I2C-Bus port, unit includes 2 user-definable uncommitted TTL-level I/O lines.
Original Press Release:
Versatile, Unique USB-to-I2C Adapter for PCs
Fairport, New York. UCA93LV is a new fully-featured USB to I2C-Bus Communications Adapter made by CalibreUK, the industry standard leader in I2C-Bus Communications Adapters for PCs.
UCA93LV supports all I2C-Bus-compliant protocols including Master and Slave in 8-bit and 10-bit/extended addressing formats in both 100kHz and 400kHz high-speed modes. UCA93LV can also non-invasively real-time monitor an external I2C-Bus with new real-time data filtering features to allow specific addresses to be monitored, as well as a full data-logging mode.
UCA93LV builds on Calibre's well-proven ICA90 & PCI90 I2C-Bus Communications Adapters which are now widely regarded as the industry standard tool, thousands of which are currently in use worldwide.
UCA93LV can work with I2C-Bus systems running on supplies between 1.8V and 5V so it's ideally suited for use in low-power applications. Additionally, it's USB-bus-powered so it needs no external supply or batteries. I2C bus voltage selection is software programmable and UCA93LV includes protection circuitry to ensure that the unit is not damaged if accidentally connected to a bus voltage different from that for which it is configured. UCA93LV works authentically at its programmed voltage providing selectable bus pull-ups at the appropriate voltage and does not simply clamp the incoming levels to a lower voltage - it is truly voltage programmable, not simply 5V tolerant.
In addition to the I2C-Bus port, UCA93LV also includes two user-definable uncommitted TTL-level I/O lines which can be used for monitoring or driving external circuitry such as system resets, address select lines or interrupt flags. I2C is a two-wire bus that is widely used in television and audio systems, cellphones, power supplies and other systems to keep cable connections to a minimum.
The UCA93LV package includes the USB - I2C-Bus Adapter module, a 6 ft. USB cable, a comprehensive user manual, Windows 98/2000/Me/xP device drivers to enable users to integrate the product with their own software applications, and a real-time I2C-Bus monitor program. Ready-to-run WINI2C software for immediate control and development of I2C-Bus systems is also available as an optional extra and is strongly recommended for new users.
UCA93LV will be available from July 1, 2003 at $499 from Saelig Company (585-425-3753; 585-425-3835fax; sales@saelig.com; www.saelig.com).
