XA9500XL Automotive Requirements and Recommendations
Requirements
The following requirements are for all automotive applica-
tions:
1. All automotive customers are required to keep the
Macrocell Power selection set to low, and the Logic
Optimization set to density when designing with ISE
software. These are the default settings when
XA9500XL devices are selected for design. These
settings are found on the Process Properties page for
Implement Design. See the ISE Online Help for details
on these properties.
2. Use a monotonic, fast ramp power supply to power up
XA9500XL . A V_CC ramp time of less than 1 ms is
required.
3. Do not float I/O pins during device operation. Floating
I/O pins can increase I_CC as input buffers will draw
1-2 mA per floating input. In addition, when I/O pins are
floated, noise can propagate to the center of the CPLD.
I/O pins should be appropriately terminated with
keeper/bus-hold. Unused I/Os can also be configured
as C_GND (programmable GND).
4. Do not drive I/O pins without V_CC/V_CCIO powered.
5. Sink current when driving LEDs. Because all Xilinx
CPLDs have N-channel pull-down transistors on
outputs, it is required that an LED anode is sourced
through a resistor externally to V_CC. Consequently, this
will give the brightest solution.
6. Avoid external pull-down resistors. Always use external
pull-up resistors if external termination is required. This
is because the XA9500XL Automotive CPLD, which
includes some I/O driving circuits beyond the input and
output buffers, may have contention with external
pull-down resistors, and, consequently, the I/O will not
switch as expected.
7. Do not drive I/Os pins above the V_CCIO assigned to its
I/O bank.
