MB90340E Series

(2) Reset Standby Input

(TA

= −40 °C to +105 °C, VCC = 5.0 V ± 10%, fCP ≤ 24 MHz, VSS = AVSS = 0.0 V)

* : The oscillation time of the oscillator is the time it takes for the amplitude of the oscillations to reach 90

%. For

crystal oscillators, this time is between several ms and several tens of ms, for ceramic oscillators the time is

between several hundred

µs and several ms, and for an external clock, the time is 0 ms.
