| EM MICROELECTRONIC - MARIN SA EM4083 3D Active Long Range Front-End General Description The EM4083 is a CMOS integrated circuit intended for hands-free or multidimensional wireless communication systems at 125kHz. It integrates a high sensitivity low frequency AM receiver together with digital functions accessible through a Serial Standard Interface. EM4083 provides a wake-up signal to an external microcontroller upon reception of a valid programmable header and then a high-speed data transfer and decoding for long range applications at 125kHz. Key Features 115kHz -140kHz Frequency Bandwidth 3 antennas interface for 3D reception Ultra low current consumption < 2A High sensitivity (1mVpp) More than 2.5m distance in typical applications. 32x16 bits EEPROM (432 bits user memory). On Chip capacitors for antenna tuning On Chip resistor for Antenna Quality Factor tuning 4 wires Microcontroller Serial interface (SPI). 8 bits (EEPROM programmable) Header detection. Manchester data decoder (data rate 4Kbd). Data transmission performed by 100% amplitude modulation (OOK) in Up-Link. -40C to +85C Temperature range. 3V power supply battery TSSOP16 package.
