45 / 67 page MB90540/540G/545/545G Series 45 (2) Clock Output Timing (MB90F543/F549 : VCC = 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = −40 °C to +85 °C) (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 MB90F543/F549/543G(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 (MB90F543/F549 : VCC = 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = −40 °C to +85 °C) (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 MB90F543/F549/543G(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 FAR/ceramic oscillator, the oscillation time is between handreds of µs 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.
