EM MICROELECTRONIC - MARIN SA EM9201 1Mbps, low power 2.4 GHz Transceiver Description Features EM9201 is a 1Mbps low power, low-voltage 2.4GHz transceiver IC with built-in link-layer logic suitable for proprietary wireless links in the 2.4 GHz ISM band. EM9201 features a radio core with a low-IF architecture and GFSK modulation scheme being compliant with the Bluetooth low energy technology standard. Control of the link-layer logic is possible though a standard SPI interface. To achieve this, an external host-controller MCU is required. EM9201 can operate from a 3V battery or any other source of power such as an external LDO regulator.
