CoolRunner-II Automotive Requirements and Recommendations
Requirements
The following requirements are for all automotive applica-
tions:
1.
Use a monotonic, fast ramp power supply to power up
CoolRunner-II. A VCC ramp time of less than 1 ms is
required.
2.
Do not float I/O pins during device operation. Floating
I/O pins can increase ICC 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
bus-hold or pull-up. Unused I/Os can also be configured
as CGND (programmable GND).
3.
Do not drive I/O pins without VCC/VCCIO powered.
4.
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 VCC. Consequently, this
will give the brightest solution.
5.
Avoid pull-down resistors. Always use external pull-up
resistors if external termination is required. This is
because the CoolRunner-II 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.
