MALVERN, Pa. — August 9, 2006 — In a move to reduce time to market for designers using its ambient light sensors, Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new light sensing development kit that allows development engineers to measure and display ambient illumination, tune the sensor, define their software program responses, and complete a hardware layout. The development kit supports Vishay's recently introduced ambient light sensor portfolio.

For hardware, the built-to-order development kit includes an adapter board and sensor board. The sensor board includes the ambient light sensor chosen to be evaluated by the customer, an analog-to-digital converter, and I2C interface. The adapter board converts the I2C output from the sensor board to the RS-232 interface for direct PC connection. With the direct PC connection, development engineers can use the sensor and adapter board combination to quickly define system responses to various lighting conditions. To reduce prototype development time and cost, engineers can integrate the sensor board, connecting the I2C interface directly to their product's controller.

For software, the development kit includes Microsoft® Windows®-based software that displays the ambient illumination in a variety of formats including lux, microamps, voltage, decimal, and hexadecimal. In addition, a bar graph displays the ambient light in lux. The software is used to tune the sensor by programming the sampling rate and gain. There are two data sampling modes: continuous sampling at user defined intervals and single or trigger mode where a single data reading is taken.

Vishay's ambient light sensors help reduce power consumption in consumer electronics applications by controlling keypad backlights and adjusting the brightness of LCDs. In addition to improving display visibility and reducing power consumption, the sensors are an environmentally friendly alternative to cadmium-based photo resistors, the elimination of which has been mandated by Restriction of Hazardous Substances (RoHS) legislation.

The development kit is available now using one of the following ordering codes: TEMT6200FDevKit, TEMT6000DevKit, TEPT5700DevKit, TEPT4400DevKit, or TEPT5600DevKit. Lead time is four weeks.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets. Vishay’s product innovations, successful acquisition strategy, and "one-stop shop" service have made it a global industry leader. Vishay can be found on the Internet at www.vishay.com.
