  • transceiver integrated circuit EM Microelectronic Marin
The EM9201/02 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 EM9201/02 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 EM9201/02 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
