Atmel - one stop shop for Remote Access Control

With its AVR microcontrollers, Smart RF radios and reference software, Atmel provides a complete solution for Remote Access Control designs. "With a complete system including microcontroller, radio and software, we believe we provide customers with a problem-free and fast solution, allowing a shorter time to market," said Magnus Pedersen, Atmel's Director of AVR RF Marketing.

By using AVR microcontrollers, the system provides excellent performance and flexibility to meet the requirements for a modern RAC system. In addition, the AVR microcontroller is still left with resources to serve other parts of the application, such as motor control, lights, relays etc.

More than 10 years of life for battery-operated transmitter

By combining the very low power ATtiny45 microcontroller with the T575x PLL transmitter, the system enables a fast but very power-efficient solution. Spending most of the time in sleep mode combined with no more than 30 milliseconds response time in active mode, a battery life of more than 10 years is achieved by transmitter fobs.

RAC software with Advanced Encryption Standard (AES) encryption free of charge from Atmel

Security is provided by license-free AES software. Multiple security levels are available as the system supports 128-, 192- and 256-bit AES key strengths. The solution offers great flexibility based on a modular software architecture that is easily customized to fulfill customer needs. Even though the system offers multiple security levels and a modular approach, it is still very efficient with a response time of less than 30 milliseconds.

License-free ISM (Industrial, Scientific, Medical) frequency band operation

By using Atmel's own T575x PLL transmitters and ATA5743 RF receiver, the RAC solution enables operation in the ISM band at 315 MHz or 434 MHz. The T5753 transmitter supports 315 MHz while 434 MHz is supported by T5754. The T5743 receiver supports both 315 MHz and 434 MHz communication. The ISM band is license free and available in most parts of the world.

STK512 Remote Access Control - Unidirectional kit

Atmel's STK512 kit contains a unidirectional radio system consisting of a battery operated transmitter (ATtiny45 + T575x), and a receiver (ATA5743) for mounting on the STK500 AVR starter kit (STK500 is not included). Together with STK500, the STK512 provides a complete development environment for RAC applications.

The STK512 starter kit is available in two different versions covering 315 MHz or 434 MHz as designated by the part number suffix -3 or -4 respectively, both including fully featured Advanced Encryption Standard (AES) rolling code software.
