Thermal Characteristics
Introduction
The temperature variable in the Actel Designer software refers to the junction temperature, not the
ambient temperature. This is an important distinction because dynamic and static power consumption
cause the chip junction to be higher than the ambient temperature.

Region 1: I/O buffers are OFF
Region 2: I/O buffers are ON.
I/Os are functional (except differential inputs)
but slower because VCCI / VCC are below
specification. For the same reason, input
buffers do not meet VIH / VIL levels, and
output buffers do not meet VOH / VOL levels.
