The Embedded I/O Company

TPMC683

32 RS422/RS485 Differential I/O

Application Information

The TPMC683 is a standard single-width 32 bit PMC

module

offering

32

differential

I/O

lines

using

EIA-422 / EIA-485

compatible,

ESD-protected

line

transceivers.

Each line is individually programmable as input or output.

The

receivers

are

always

enabled,

which

allows

determining the state of each I/O line at any time. This can

be used as read back function for lines configured as

outputs.

Each input can generate an interrupt. Signal edge

handling is programmable to interrupt on rising and/or

falling edge of an input signal. Interrupts can be enabled

and disabled for each bit. For interrupt source detection,

the status of each line can be read from interrupt status

registers.

The TPMC683 provides front panel I/O via a HD68 SCSI-3

type connector and rear panel I/O via P14.

Software

Support

(TDRV012-SW-xx)

for

different

operating systems is available.
