Application Information

The TPMC866 is a standard single-width 32 bit PMC

module and has eight channels of high performance

asynchronous serial interface with front I/O and back I/O.

The TPMC866-10R offers 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-

Terminal-Ready (DTR), Data-Carrier-Detect (DCD) and

Ring-Detect-Indicator (RI).

The TPMC866-11R supports an 8 channel RS422

interface and offers RS422 signal levels by differential

transmitters and receivers. The Transmit Data (TxD +/-),

Receive Data (RxD +/-) and GND are provided for each

serial channel. The receiver signal termination (120ohms

between RxD+ and RxD-) is provided on the TPMC866

per channel.

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 transmitter and receivers. The FIFO trigger

levels are programmable.

For all modules the baud rate is individually programmable

up to 460.8 Kbaud per channel. All channels use the PCI

interrupt INTA together but for fast interrupt source

detection the TPMC866-xxR provides a special interrupt

status register. Receiver and transmitter are protected

against electrostatic discharge (ESD).

All TPMC866 modules are available in extended

temperature range as TPMC866-xxR-ET versions.

Software support (TPMC866-SW-xx) for different

operating systems is available.
