TPMC681

64 Digital Inputs/Outputs (Bit I/O)

Application Information

The TPMC681 is a standard single-width 32 bit PMC

module offering 64 ESD-protected TTL I/Os. Each 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

TTL 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 bit. 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.
