8. Bus-friendly Pin-keeper Input and I/Os
All input and I/O pins on the ATF750LVC have programmable “pin-keeper” circuits. If acti-
vated, when any pin is driven high or low and then subsequently left floating, it will stay at that
previous high or low level.
This circuitry prevents unused input and I/O lines from floating to intermediate voltage levels,
which cause unnecessary power consumption and system noise. The keeper circuits elimi-
nate the need for external pull-up resistors and eliminate their DC power consumption.
Enabling or disabling of the pin-keeper circuits is controlled by the device type chosen in the
logic compiler device selection menu. Please refer to the software compiler table for more
details. Once the pin-keeper circuits are disabled, normal termination procedures are required
for unused inputs and I/Os.
