EM Microelectronic EM9203
The EM9203 is a 1Mbps or 2Mbps low-power, low-voltage, completely-integrated 2.4GHz ISM band RF transceiver ideal for battery operated wireless applications such as wireless sensors and control, audio streaming, human interface devices, and security networks. The EM9203’s built-in baseband processor (with link-layer) permits implementation of optimized proprietary wireless protocol links in the license-free 2.4000GHz to 2.4835GHz ISM band. It includes a low-IF receiver architecture and uses GFSK modulation compliant with the emerging Bluetooth Low Energy (4.0) standard.| Part No. | EM9203 |

DESCRIPTION
An industry-standard SPI interface provides for simple control of the baseband using an external host controller. The EM9203 Version 11 features an integrated step-up (boost) DC/DC converter that allows operation with supply voltages as low as 0.8V with an external coil. This converter is designed to support an additional load such as a lowpower microcontroller (host) and interface circuits with a dedicated application profile. The EM9203 Version 12 can be supplied by a 3V battery or other voltage source. Available chip versions:● Version 11: with DC/DC converter for use with 1.5V battery (down to 0.8V)
● Version 12: without DC/DC converter for use with any voltage from 1.9V to 3.6V Simplified Application Schematic SW_DCDC VSS_DCDC VBAT VCC2 XTAL1 XTAL2 VDD
