Interface_KNX/EIB Transceiver

All members of the Elmos KNX family can be used as bit transceivers in analogue mode if required. The two family members E981.03 and E981.23 feature a TP-UART-compatible protocol with up to 115kBaud.  The E981.33 functions only as a bit transceiver. With the E981.03, an SPI for configuration and diagnosis is available in addition. All family members have an integrated DC/DC voltage regulator that supplies either 5 or 3.3 volts. All of them also have a linear voltage regulator for 20V/25mA.
