Atmel’s ATA874x single-chip UHF ASK/FSK RF transmitter family targets a broad range of proprietary wireless industrial and consumer applications such as metering, alarm systems and home control applications. This new AVR® product family offers RF performance operating in the license-free ISM frequency bands (868 to 928 MHz, 433 MHz, and 315 MHz).
With a low-power AVR CPU, a highly effective RF transmitter, and a sleep-mode power consumption of only 160 nA, the ATA874x family members are uniquely optimized to address battery-driven applications such as remote controls or garage door openers. The tiny QFN24 packages, measuring only 5 mm x 5 mm, allow the creation of extremely small designs. The new ATA874x devices incorporate Atmel's RF transmitter technology.
The ATA874x devices use the ATtiny44V CPU, allowing in-system flash memory re-programming. By executing powerful instructions in a single-clock cycle, the ATtiny44V achieves throughputs approaching 1 MIPS per MHz that enable system designers to optimize power consumption versus processing speed. The powerful AVR controller simplifies hardware and software designs.
The key features of Atmel's new, microcontroller-based RF solution include technologies shipped in various products since 2001. The 8-bit microcontroller AVR CPU has been incorporated into countless products and Atmel has shipped more than a billion units. Atmel's RF technology reportedly satisfies even the strictest quality and reliability demands of the automotive market. Customers that have worked with AVR or earlier RF products can reuse existing RF transmitter or AVR designs and software, thus reducing both development costs and time-to-market.
The ATA874x single-chip narrow band transmitter family complements Atmel ISM band receivers, including the ATA8201, ATA8202 or ATA8203/4/5.
To simplify and accelerate product design, a complete design kit for uni-directional RF applications, as well as Atmel's AVR Studio® for new software development (STK512-EKx-IND), are available for customer lab measurements and performance evaluations.
