7.7 Power-On Reset (POR)
Figure 3
shows a possible curve of V
CC(I/O)
with dips at t2 to t3 and t4 to t5. At t0, POR will
start with 1. At t1, the detector passes through the trip level. Another delay will be added
before POR drops to 0 to ensure that the length of the generated detector pulse, POR, is
large enough to reset asynchronous flip-flops. If the dip is too short (t4 to t5 < 11
μ
s),
POR will not react and will stay LOW.
7.8 Power supply
Figure 4
shows the ISP1562 power supply connection.
V
POR(trip)
is typically 1.2 V.
