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). Features • Signaling for standard UART (LSB-First, Idle is 1) • Baud rate 9600 or 19200 baud for the communication: TP - UART <--> Host - Controller • Direct coupling to host controller (TxD, RxD), or via optical couplers (optional) • 2 - wire protocol with software handshake • Buffering of send frames • No critical timing during transmission • 64 Byte telegram buffer • Operating temperature range: -25°C to 85°C • Supervision of EIB bus voltage VB - Tx0 Rx IN MODE 0 MODE 1 TEST MODE X 1 X 2 TSTOUT RxD 11 12 13 14 15 16 17 18 19 20 10 9 8 7 6 5 4 3 2 1 VB + VSP CSA VCC DIV SAVE TSTIN VIF RESn TxD |
