Power-Up Specifications
All functionalities and DC specifications are specified for a V
DD
ramp rate faster than 1V per 100 ms
(0V to 3V in less than 300 ms). If the V
DD
ramp rate is slower than 1V per 100 ms, a hardware reset is
required. The recommended V
DD
power-up to RESET# high time should be greater than 100 µs to
ensure a proper reset. See Table 19and Figure 4 for more information.
