The TPMC681 is a standard single-width 32 bit PMC module offering 64 ESD-protected TTL I/O lines.
Each I/O line is individually programmable as input, output or tri-state.
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 I/O line has a pull-up resistor. The pull-up voltage is selectable to be either +3.3V or +5V.
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 I/O line. For interrupt source detection the status of each bit can be read from interrupt status registers.
The TPMC681 provides front panel I/O via a HD68 SCSI-3 type connector and rear panel I/O via P14.
Software Support (TDRV006-SW-xx) for different operating systems is available.
