TEWS TPMC371 Conduction Cooled PMC, 8 Channel RS232/RS422

Application Information

The TPMC371 is a conduction cooled single-width 32 bit

PMC module and offers 8 channels of high performance

asynchronous serial interface.

Three different standard modules are available: The

TPMC371-10xR provides 8 RS232 interfaces. The

TPMC371-11xR provides 8 RS422 interfaces. The

TPMC371-12xR provides 4 RS232 and 4 RS422 interfaces.

Other configurations are available as factory build option

on a per channel base.

All modules offer P14 I/O. Each RS232 channel supports

RxD, TxD, RTS, CTS and GND. Each RS422 channel

supports RxD+/-, TxD+/- and GND. Two channels of the

TPMC371-10xR/-12xR offer full modem support (TxD,

RxD, CTS, RTS, DSR, DTR, CD, RI and GND) for RS232.

Two channels of the TPMC371-11xR support RxD+/-,

TxD+/-, RTS+/-, CTS+/- and GND for RS422.

Each channel has 64 byte transmit and receive FIFOs to

significantly reduce the overhead required to provide data

to and get data from the transmitters and receivers. The

FIFO trigger levels are programmable and the baud rate is

individually programmable up to 921.6 kbps for RS232

channels and 5.5296 Mbps for RS422 channels. The

UART offers readable FIFO levels.

All channels generate interrupts on PCI interrupt INTA. For

fast interrupt source detection the UART provides a

special Global Interrupt Source Register.

All serial channels use ESD protected transceivers. ESD

protection is up to ±15KV.

The TPMC371 can operate with 3.3V and 5.0V PCI I/O

signaling voltage.

Software Support (TDRV002-SW-xx) for different

operating systems is available.
