SINGLE-CELL BATTERY 2.4GHZ RADIO TRANSCEIVER

23 DECEMBER 2008

EM Microelectronic, the semiconductor company of the Swatch Group and leading supplier of analog and mixed-signal semiconductors for Ultra Low Power applications, announced the world’s first single-cell battery 2.4GHz standalone radio compatible with Bluetooth low energy wireless technology. This new device is optimized for low voltage and low energy applications such as wireless sensors and wireless monitoring. The EM9201 is an ISM radio frequency (RF) 2.4GHz transceiver; with its integrated DC/DC converter, it is capable of operating the RF transceiver while delivering up to 100mA to an external device, thus ensuring the lowest power supply and power consumption on the market. Such a result can be achieved using a single-cell battery; furthermore, with operation voltage as low as 0.85V, it enables applications to take advantage of the wide choice of low cost batteries available. To optimize the systems power budget, a proprietary concept can be used to place the radio in the “Xtreme” low power idle mode in which the circuit itself consumes less than 3µA, while still supplying up to more than 2V/500µA to an external device. With an Ultra Low Power receiver (RX) and transmitter (TX), the EM9201 is significantly increasing battery life in portable wireless applications.
