(2) Clock Output Timing
(MB90543G(S)/547G(S)/548G(S)/F548GL(S): VCC
= 3.5 V to 5.5 V, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
(Other than MB90543G(S)/547G(S)/548G(S)/F548GL(S):
VCC
= 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
(3) Reset and Hardware Standby Input Timing
(MB90543G(S)/547G(S)/548G(S)/F548GL(S): VCC
= 3.5 V to 5.5 V, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
(Other than MB90543G(S)/547G(S)/548G(S)/F548GL(S):
VCC
= 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
Note : “tcp” represents one cycle time of the machine clock.
Oscillation time of oscillator is time that amplitude reached the 90
%. In the crystal oscillator, the oscillation
time is between several ms to tens of ms. In ceramic oscillator, the oscillation time is between handreds of
s to several ms. In the external clock, the oscillation time is 0 ns.
Any reset can not fully initialize the Flash Memory if it is performing the automatic algorithm.
