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 pullup
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.
