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).

1.2.4 Supply Pin VCC (Pin 7)
The pin VCC delivers the internal generated voltage supply to external loads. An external
short-circuit from the VCC pin to GND will not cause a destruction of the ASIC.

TP-UART-IC
The UART-interface works with a clock frequency of 307,2 kHz, if it is chosen 9.6 kbaud (32
sample spots per bit), or 614,4 kHz, if it is chosen 19.2 kbaud (32 sample spots per bit).
3.2.2 Resetbehavior
After connecting the operating voltage the TP-UART-IC generates an active reset
(level 0 V) at pin RESn. This is valid for all modes. If Normal Mode is activated the following
will happen at the UART-interface.
TxD will be 0 as long as there was no bus signal on the EIB for 40 Tbit (1 Tbit = 1/9600 s;
Attention: The bittime of RxD/TxD depends on the adjusted baudrate at the UART-interface,
for example 1 Tbit or 0,5 Tbit). This results in a complete time of 40 Tbit + 12 Tbit = 5,42 ms.
Then TxD changes for 1 Tbit to 1 and following the service TPUART-Reset.Indication is
transmitted. This signal behavior on TxD appears after each reset.
3.2.3 UART-Protocol Definition
The protocol between TP-UART-IC and the application controller is a two wire protocol with
software handshake. Each data byte transmitted to the TP-UART-IC is started with a control
byte. Each data byte received on the EIB is transparently transmitted through the TP-UART-
IC and is therefore started with the EIB control field. Additional Information from the TP-
UART-IC is transmitted with an ESC code on the EIB control field. The host controller which
is connected to the TP-UART-IC needs to detect a receive time-out of 2 to 2,5 ms to detect
an end of Packet.
