Product Specification
R
mented in the buried macrocell can be fed back to the ZIA
via the macrocell feedback path.
If a macrocell pin is configured as a registered input, there is
a direct path to the register to provide a fast input setup
time. If the macrocell is configured as a latch, the register
clock input functions as the latch enable, with the latch
transparent when this signal is High. The hardwired clock
enable is non-functional when the macrocell is configured
as a latch.
I/O Cell
The OE (Output Enable) multiplexer has eight possible
modes (Figure 6). When the I/O Cell is configured as an
input (or 3-stated output), a half latch feature exists. This
half latch pulls the input High (through a weak pull-up) if the
input should float and cross the threshold. This protects the
input from staying in the linear region and causing an
increased amount of power consumption. This same weak
pull-up can be enabled in software such that it is always on
when the I/O Cell is configured as an input. This weak pull
up is automatically turned on when a pin is unused by the
design.
The I/O Cell is 5V tolerant when the device is powered.
Each output has independent slew rate control (fast or slow)
which assists in reducing EMI emissions.
See individual device data sheets for 3.3V PCI electrical
specification compatibility.
Note that an I/O macrocell used as buried logic that does
not have the I/O pin used for input is considered to be
unused, and the weak pull-up resistors will be turned on. It
is recommended that any unused I/O pins on the CoolRun-
ner XPLA3 family of CPLDs be left unconnected. Dedicated
input pins (CLKx/INx) do not have on-chip weak pull-up
resistors; therefore unused dedicated input pins must have
external termination. As with all CMOS devices, do not
allow inputs to float.
