TEWS TPMC321 Conduction Cooled, 64 Digital TTL I/O / 32 Differential I/O

Application Information

The TPMC321 is a conduction cooled single-width 32 bit

PMC module offering 64 ESD-protected 5V-tolerant TTL

lines or 32 differential I/O lines using ESD-protected EIA

422 / EIA-485 compatible line transceivers or Multipoint

LVDS transceivers.

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.

Differential I/O lines are terminated, EIA-422 / EIA-485

lines with 120 Ω, M-LVDS lines with 100 Ω.

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 TPMC321 provides rear I/O via P14.

Software Support (TDRV006-SW-xx) for different

operating systems is available.
