The integrated ultra-low power receiver technology RFicient® was developed for ISM frequency bands and built in standard CMOS technology. The receiver operates
Multi-band sub-1-GHz, at 433 MHz, 868 MHz and 2.4 GHz and achieves a receiver sensitivity of -80 dBm. When operating in the standard configuration at a data rate of 1 kbit/s, the current consumption is reduced below 3 μA at 1.8 V with a response time of only 30 ms.
The integrated ultra-low power receiver RFicient® operates without the use of a microcontroller and recognizes two separate wake-up patterns. After receiving a specific wake-up pattern, a digital control signal is generated to activate any application hardware like a MCU.
Apart from the pure wake-up mode of operation, a selective activation using a 16-bit wide address range and reception of coded data streams is possible. Furthermore, basic functions, frequency bands and additional functionality can be modified to fit the customers’ needs.
The Fraunhofer Institute for Integrated Circuits IIS provides detailed documentation and support for the IP integration. Modifications, extensions and technology ports of the IP are available on request.
