Product Description
The PXM-UIO96-2 is a high-performance, 96-channel
digital I/O controller implemented on a stackable SUMIT-
AB compliant Industry Standard Module (ISM). The major
feature of this card is its ability to monitor 96 lines for both
rising and falling digital edge transitions, latch them and
then interrupt the host processor notifying that a change-
of-input status has occurred. It is based upon a Lattice
Semiconductor ECP2M family FPGA with a superset of two
WS16C48 Universal I/O controller cores.
Parallel I/O Controller - WinSystems designed the
WS16C48 Universal I/O controller ASIC to support the
various input/output and interrupt configurations. Each
WS16C48 supports 48 digital I/O lines addressed through
six contiguous registers. A six-bit Write Mask register allows
the user to disable Writes on a byte basis to configure the
group as a “Read Only” port.
Every I/O line is individually programmable for input,
output, or output with Read back operation. The input lines
are connected so the current status of its output port can
be read from the corresponding input port (Read back).
If the port is used as input only, then the corresponding
output port bit must be cleared.

Each output channel is latched and has an open collector
driver (with a pull-up resistor) capable of sinking 12mA of
current. This allows direct control of up to 96 optically-iso-
lated signal conditioning modules to a single card for high
density I/O support.
