MCU packs RF transmitter, low-power CPU

The ATA874X MCU range features low-power AVR CPU, highly-effective RF transmitter, and sleep-mode power consumption of 160nA. This can be optimally used in battery-driven applications such as remote controls or garage door openers. The QFN24 packages, measuring 5mm x 5mm, can be used to create small designs at competitive costs. Customers can benefit from a BOM cost savings of up to 30 per cent and board-area savings of up to 50 per cent, when compared with conventional solutions.

The ATA874x devices offer maximum flexibility using 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 optimise power consumption versus processing speed. The powerful AVR controller simplifies hardware and software designs.

The ATA874x single-chip narrow band transmitter family complements the Atmel ISM band receivers and seeks to provide a total end-to-end solution to its customers.

Samples of the ATA874x family are now available in small-outline QFN24 packages. Pricing starts at Rs.48.82 ($1) for quantities of 200,000. To simplify and accelerate product design, a complete design kit for unidirectional 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.
