Semiconductor solutions developer Atmel Corp. has revealed that its multi-channel transceiver is being used in Metl-Tech Racer's line of tiny, remote-controlled race cars.

Metl-Tech Racers are "matchbox-sized" remote control cars. Their high-tech electro-mechanical design makes them the first miniature indoor R/C racers. A unique high-frequency transmitter from Atmel sends data to the vehicle to precisely control steering and speed. It combines radio frequency, mechanical and microcontroller design to create a reliable, digital-proportional remote-controlled mini-vehicle. The cars have great maneuverability made possible by a patent-pending Digital Proportional electronic design. They provide players with hours of challenging driving enjoyment, racing against friends on a conference table or floor. They also can help develop driving skills by using them to learn parallel parking or maneuvering around objects on a desk.

Metl-Tech designers cite the level of integration of Atmel's SmartRF AT86RF211 transceiver that allowed them to meet the dimensional constraints of a car that's just 2-3/4-inches (7cm) long. They also commented that the Atmel transceiver includes all RF functions embedded on silicon, requiring a small number of external components and can be controlled by any low-cost microcontroller. Atmel's technical support was also mentioned as a key design attraction.

Prototypes submitted for lab testing complied with Part 15 of the Federal Communication Commission's regulations when first tested, this not being typically common for RF products. The FCC governs operation of RF transmitters in the unlicensed ISM 902-928MHz frequency bands.
