The new low-cost 2.4 GHz transceiver CYRF7936 was developed by Cypress Semiconductor Corporation and is specially designed for home automation, health-care applications, remote controls and wireless sensor networks. With its voltage range from 1.8 V to 3.6 V the device is ideally suited for battery powered systems.
A special feature protocol was developed based on the PSoC® microcontroller. It has a memory requirement of only 5 kByte for a node and 8 kByte for a hub. The highly effective CYFi Star Network Protocol recognizes the optimal data transfer rate and output power. In case of interruptions, it switches automatically from the highest data transfer rate of 1 Mbps in Gaussian Frequency Shift Keying to the safe Direct Spread Spectrum transmission method at 250 kbps. Output performance is increased to the maximum +4 dBm as soon as the connection is interrupted. When operating with two AA battery cells, the typical lifetime is 4 years due to the power saving protocol and very good technical parameters of the transceiver. Another remarkable feature is that designs based on the CYRF6936 can be used further, because matching and pinout comply with the CYRF7936. The demo kit CY3271 is from towards onward available at the MSC Vertriebs GmbH. For further information please contact: radio-frequency@msc-ge.com.
