EM 9201 transceiver

The EM9201 is a low-voltage 2.4GHz transceiver IC with built-in link-layer logic permitting proprietary wireless links in the 2.400 2.485 GHz ISM band. It has a radio core with a low-IF architecture and GFSK modulation scheme
being compatible with the emerging Bluetooth low energy technology standard. The specification of this new wireless technology will be released during the second half of 2009 and it is expected to be in devices within the following couple of months.

The EM9201 can be operated from a single 1.5V battery by making use of the on-chip step-up (boost) DC/DC converter. This converter is designed to support an extra load such as a low-power microcontroller (host) or sensor interface circuit with a dedicated application profile. The EM9201 can also operate without the DC/DC converter, when supplied from a 3 V battery or any other source such as an external LDO regulator. No external coil is needed then. These two possibilities are programmable by a metal mask option:

V1: with DC/DC converter for 1.5V battery
V2: w/o DC/DC converter for any voltages 1.9 3.6V

Applications:
* Remote sensing in general
* Wireless mice, keyboards etc.
* Wireless sensors in watches
* Wireless sports equipment
* Alarm and security systems
