TPMC866-11R  TEWS 8 Channel Serial Interface

Product Description

The TPMC866 is a standard single-width 32 bit PMC module and provides eight channels of high performance serial interface with front I/O and P14 back I/O.
The TPMC866-10R provides an 8 channel RS232 interface and supports Receive Data (RxD),
Transmit Data (TxD), Ready-To-Send (RTS), Clear-To-Send (CTS) and GND for each channel.
Additionally serial channel one and serial channel two provide Data-Set-Ready (DSR), Data-TerminalReady (DTR), Data-Carrier-Detect (DCD) and Ring-Detect-Indicator (RI).
The TPMC866-11R provides an 8 channel RS422 interface using differential line transceivers. The Transmit data (TxD +/-), Receive Data (RxD +/-) and GND signals are provided for each serial channel. The receiver signal termination for each channel (120ohm between RxD+ and RxD-) is provided on board the TPMC866.
Each channel of the TPMC866-10R/11R has a 64 byte transmit FIFO and a 64 byte receive FIFO to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers.
The baud rate is individually programmable for up to 460.8Kbaud per channel.
All channels use the PCI interrupt INTA. For fast interrupt source detection the TPMC866-xx provides an Interrupt Status Register covering all interrupt sources. I/O line transceivers are protected against electrostatic discharge (ESD).
All TPMC866 modules are available in extended temperature range as TPMC866-xx-ET versions.
