146 / 280 page ![]() Document Number: 002-04662 Rev. *F Page 146 of 280 MB91520 Series (2) Reset Input (TA: -40 °C to +125 °C, VCC = AVCC = 5.0 V ± 10 %/VCC = AVCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V) Parameter Symbol Pin Name Conditions Value Unit Remarks Min Max Reset input time tRSTL RSTX – 10 – µs When normal operation Oscillation time of oscillator* +100 – µs At Stop mode At Power-on*2 100 – µs At Watch mode Width for reset input removal 1 – µs *1: 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. *2: In case of using MB91F52xxxD or MB91F52xxxE and corresponding to note in (3) Power-on Conditions of next subsection, assert RSTX with power-on. RSTX 0.2 vcc 0.2 vcc tRSTL At Stop mode 0.2 VCC 100 μs RSTX X0 90% of amplitude Internal operation clock Oscillation time of oscillator Oscillation stabilization waiting time Instruction execution Internal reset 0.2 VCC tRSTL |
