CSEM's new Sub-1V Bluetooth Smart RF transceiver IP offers best-in-class per-formance for wearable sensors and IOT

Switzerland, August 20, 2014- CSEM has announced the availability of IcyTRX-65, a 2.4GHz sili-con RF IP optimised for low power Bluetooth Smart (Bluetooth Low Energy) circuits. Consuming only 5mW and directly powered from a 1V battery, IcyTRX-65 sets a new benchmark for low pow-er BLE circuits.

When IcyTRX was released in 2012 it set a new level of performance for low power 2.4GHz RF IPs. The last two years have witnessed an explosion of demand for BLE-connected sensors, for sports, healthcare and wearable sensors, driving new demands for even higher performance solutions.

CSEM has now introduced "IcyTRX-65", a 65nm CMOS version of the IcyTRX IP, offering even lower power performance: 5mA current consumption directly from a 1V battery, a best-in-class sensitivity of -97dBm and a transmitter frequency synthesizer settling time of only 5μs, along with full BT4.1 compliance. IcyTRX-65 operates down to 0.9V, allowing the use of small coin-cell batteries. The unique architecture results in a highly integrated solution, with a die size of less than 2mm2, and no external matching components required. Furthermore the flexible and programmable baseband offers a programmable data-rate up to 4MB/s and allows use with IEEE802.15.4 protocols (e.g. Zigbee) as well as with proprietary protocols.

IcyTRX-65 is silicon proven and available for license. It is fully characterized, exceeding the requirements of BT4.1, and samples and evaluation kits are available.
