EM9202
Description
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. An FPGA bridge is included in the circuit such that with an external FPGA any protocol patible with the RF characteristics can also be emulated through the SPI port of the EM9201/02. 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...
