TPMC463

4 Channel Serial Interface RS232/RS422

Application Information

The TPMC463 is a standard single-width 32 bit PMC

module and offers 4 channels of high performance

asynchronous serial interface.

Three different standard modules are available: The

TPMC463-10R

provides

4

RS232

interfaces.

The

TPMC463-11R

provides

4

RS422

interfaces.

The

TPMC463-12R provides 2 RS232 and 2 RS422 interfaces.

The TPMC463-20R provides 4 RS232 interfaces with non-

standard RJ45 I/O pinout (as used on Motorola CPU

boards).

Other configurations are available as factory build option

on a per channel base.

All modules offer front panel I/O with four RJ45 connectors

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

CTS, RTS, DTR, CD, DSR/RI and GND. Each RS422

channel supports RxD+/-, TxD+/- and GND on front and

RxD+/-, TxD+/-, RTS+/-, CTS+/- and GND on back I/O.

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 TPMC463 can operate with 3.3V and 5.0V PCI I/O

signaling voltage.
