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. Applications Keyless entry systems Tire pressure systems Intelligent sensors Intelligent access control Pinout Key Features 115kHz –140kHz Frequency Bandwidth 3 antennas interface for 3D reception Ultra low current consumption < 2µA 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. -40°C to +85°C Temperature range. 3V power supply battery TSSOP16 package. & BENEFITS Long and accurate communication range Extended battery life of the system Accurate Antenna Tuning using the Receive Strength Signal Indicator function Minimal use of external components Typical Application EM4083 Microcontroller EM6640 or EM6812 Wakeup n ASK ss_n SI Sclk So IRQ V Bat V SS V Filt RF Emitter LF Transmitter Control Unit RF Receiver HF Downlink LF Uplink (up to 2.5m) EM MICROELECTRONIC - MARIN SA 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 Vss SO ASK Wakeup_n RSSI Coil3b Coil3a Coil2b Sclk Si / Reset SS_n Vbat Vilt Coil1a Coil1b Coil2a |
