ATMEL DEBUTS IR RECEIVER IC FOR REMOTE CONTROL.

Atmel Corp., Heilbronn, Germany, (Nasdaq:ATML) has introduced a low-voltage IR (InfraRed) receiver IC for remote-control receiver applications such as TV, VCR, satellite receivers, mobile cameras, audio devices, air-conditioning systems, toys, wireless keyboards, and wireless mice. The T2526's low-voltage feature makes it also suited for all kinds of battery-driven devices, especially those operating at 3 V.

The T2526 operates at a supply voltage range of 2.7 to 5.5 V, but is optimized for the range of 2.7 to 3.6 V to support especially the 3-V mobile end products. These products will need less batteries and thus achieve smaller size which is an important issue for mobile applications. Also, the resulting lower current consumption (25% less than at 5 V) enables to design mobile end products with extended operating time. The current consumption is lower than 1 mA.

The T2526 is highly integrated, to design a complete reception unit (either module or discrete solution), only a high-performance IR-receiving diode (normally a PIN diode) has to be connected to the IC. No further external parts are required, which saves cost and space on the printed circuit board or within the module.

Additional benefits of the T2526 are its high sensitivity as well as high noise and disturbance suppression of the new receiver IC. The outstanding sensitivity performance (less than 1 nA), along with the connected PIN diode, enables a transmission distance of more than 30 meters even in dark environments when using a standard remote-control transmitter.

Due to a special regulation algorithm, noise suppression (against noise radiated from daylight or sunlight, as well as noise from energy-saving lamps, inverter-lamps and fluorescent lamps) is outstanding and thus ensures both proper operation and extended receiving distance under poor conditions.

Atmel's strategy is to provide various IR receiver solutions to meet the designers' different needs. The recently introduced IR receiver T2525 covers the conventional 5-V operating range to support the most popular high-volume applications, whereas the new T2526 is dedicated to the new emerging 3-V mobile applications with their specific need for low supply voltage and low current consumption.

The new T2526 is available with various carrier frequencies (30, 33, 36, 38, 40, 44, 56 and 78 kHz) and in 3 regulation versions. The standard version works with almost all transmission protocols used worldwide. The lamp-version ICs provide improved disturbance suppression, and the shortburst version is especially designed for applications with high data rates and short bursts. These three versions cover all popular infrared remote control applications.

Samples of the T2526 as die in tray and in SO8 packages are available now. Pricing for the T2526 in SO8 starts at 0.60 US$ (10 k).
