| 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.
