Atmel Corp. announced a reference design for wireless gaming applications that combines its low-cost 2.4GHz Smart RF transceiver and mcus reduce chip requirements" target=_blank>avr flash microcontroller (MCU) series atmega48/88/168. With this reference design, Atmel stated, system engineers can reduce development time with an application-specific tool for gaming products.

The reference design meets low cost requirements while providing excellent RF performance, the press release said. End users will enjoy link ranges beyond 10m, allowing them to freely move and ignore radio-specific limitations such as link range, line of sight or battery power drain. The design measures 17-by-28mm and is based on standard low-cost two-layer board material. Both the ATR2406 Industrial/Scientific/Medical Frequency Band (ISM) transceiver IC and the ATmega48/88/168 MCUs are clocked from a single crystal and operate at the same supply voltage. According to Atmel, this further reduces system costs.

Various components such as antenna, balun and filters are printed elements to ensure lowest BoM. The proprietary Smart RF firmware implements an adaptive frequency hopping scheme, allowing robust and reliable data transmission even in a crowded RF environment. The data rate enables throughput of up to 704kbps, while the over-the air data-rate is 1.152Mbps. The burst-mode operation reduces the current drain of the batteries, enabling extended gaming sessions without the need to recharge or change batteries.

The reference design is part of the Smart RF Transceiver ATR2406 evaluation kit, which is available for $299. Samples and kits can be ordered via Atmel sales offices or distributors.

Both the ATR2406 and the ATmega48/88/168 are manufactured in high-volume production, and are available in QFN packages as well as wafer.
