FACT SHEET | EM9203 Subject to change without notice Version 3.0, 13-Oct-14 Copyright © 2014, EM Microelectronic-Marin SA www.emmicroelectronic.com 1Volt, 2Mbps, 2.4GHz GFSK Transceiver General Description Features 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. I Low Voltage: · Single-cell, 1.5V battery operation (down to 0.8V); or · 3V battery operation (1.9V to 3.6V) 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. An industry-standard SPI interface provides for simple control of the baseband using an external host controller. The EM9203 Version 01 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 low-power microcontroller (host) and interface circuits with a dedicated application profile. The EM9203 Version 02 can be supplied by a 3V battery or other voltage source. Available chip versions: I Version 01: with DC/DC converter for use with 1.5V battery (down to 0.8V) I Version 02: without DC/DC converter for use with any voltage from 1.9V to 3.6V Simplified Application Schamtic I Low Power: · 14mA in RX Mode (2Mbps) · 14mA in TX Mode (0°dBm output power, 2Mbps) · <3µA in Xtreme Mode (Version 01) · <1µA in Power-Down Mode (Version 02) I High Performance: · -85dBm sensitivity at 2Mbps · Programmable output power from -18dBm to +3dBm I Compact radio design with low BOM cost: · MLF28 4mm x 4mm package · Operating Temperature: -40°C to +85°C · Direct antenna interface · Integrated DC/DC converter (Version 01) · Supply Voltage Level Detector (SVLD) · 26MHz crystal oscillator, frequency tolerance ±50ppm I Flexible interface: · Microcontroller compatible SPI interface · FPGA access to modulator and demodulator · External PA control signal available Applications VSS_DCDC VCC2 VBAT I Wireless audio streaming XTAL2 I Wireless mice, keyboards, toys etc. I Wireless watch sensors, sports equipment Pin Assignment IRQ SDI ANTP SDO ANTN AVSS_PLL1 XTAL1 XTAL2 EM9203 CK_FPGA AVSS_PA CSN VSS_PR AVDD_PA CSN Host Controller / Sensor-Interface IRQ AVSS_PR SDO AVSS_RF EM 9203 SDI ANTP SCK NC MLF28 4x4mm VDD AVSS_PA VBAT VCC2 AVDD_PA VCC1 VSS_DCDC BIAS_R Step-up conversion opon; for simplicity, not all supply pins indicated ANTN VSS AVSS_PLL2 BIAS_R NC VSS SW_DCDC Sensor VDD SCK I Remote sensing and control XTAL1 DATA_FPGA SW_DCDC
