TPMC460

16 Channel Serial Interface RS232/RS422

TPMC460-10R

Application Information

The TPMC460 is a standard single-width 32 bit PMC

module and offers 16 channels of high performance

asynchronous serial interface.

Five different standard modules are available: The

TPMC460-10R

provides

16

RS232

interfaces.

The

TPMC460-11R

provides

16

RS422

interfaces.

The

TPMC460-12R provides 8 RS232 and 8 RS422 interfaces.

The TPMC460-13R provides 12 RS232 and 4 RS422

interfaces. The TPMC460-14R provides 4 RS232 and 12

RS422 interfaces.

Other configurations are available as factory option on a

per channel basis.

All modules offer front panel I/O with a HD68 connector

and P14 I/O. Each RS232 channel supports RxD, TxD,

RTS and CTS. Each RS422 supports RxD+/- and TxD+/-.

A transparent 32 bit / 66 MHz PCI-to-PCI Bridge provides

access to the two Exar XR17D158 octal PCI-UARTs. The

PCI-to-PCI Bridge allows 32 bit accesses on the local PCI

bus and permits the high data throughput necessary for

the high performance serial interfaces.

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.

Interrupts

are

supported.

For

fast

interrupt

source

detection each octal UART provides a special Global

Interrupt Source Register.

All serial channels use ESD protected transceivers up to

±15KV according to IEC 1000-4-2.

The TPMC460 can operate with 3.3V and 5.0V PCI I/O

signaling voltage.

Software

Support

(TDRV002-SW-xx)

for

different

operating systems is available.
