2.3 Effect of Temperature on Timeout
Period (t
RPU)
The timeout period (tRPU) determines how long the
device remains in the reset condition. This is controlled
by an internal RC timer and is effected by both VDD
and temperature. The graph shown in Figure 2-3
shows typical response for different V
DD values and
temperatures.
