EM MICROELECTRONIC - MARIN SA EM9201/02 World’s First Fully Integrated Single-Cell Battery 2.4 GHz Transceiver Description Features 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 compliant 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 compatible 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 such as an external LDO regulator. No external coil is needed then. EM9201: up to 1 Mb/s on air data rate EM9202: up to 2 Mb/s on air data rate Chip versions, programmable by 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 Typical Application Schematic Single cell 1.5V battery operation (Alkaline AA, AAA) Operation down to VBAT = 0.8 V (for start-up --> 1.0V) 3 V Lithium battery as alternative Bluetooth Low Energy-compliant GFSK modulation Low drift of PLL frequency by design On air data rate: 1Mb/s for EM9201, configurable 1Mb/s or 2Mb/s for EM9202.
