TPMC681 64 Digital Inputs/Outputs TTL Bit I/O Module

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 of the TPMC681 PMC module 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.

A wide range of drivers is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
