EM9202 Overview
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 pliant with the emerging Bluetooth low energy technology standard. Control of the link-layer logic is possible though the SPI interface using an external host-controller.
