GENERAL DESCRIPTION
The TP - UART - IC (Twisted Pair - Universal Asynchronous Receive Transmit - IC) is a
transceiver which supports the connection of microcontrollers of sensors, actuators, or other
applications to the EIB (European - Installation - Bus).
This module supports every transmit- and receive - function and also the high ohmic decoupling
of energy from bus line. It generates further a stabilized 3.3V or 5V supply to use by a host
controller. Up to 256 subscribers can be connected to one bus line.
An UART interface is realized for communication with a host controller. The coupling can be
realized directly or via optical couplers.
The TP - UART - IC consists of two main parts: the digital part (UART - Interface) and the analog
part ( analog circuit part).
