MB90480/485 Series

(3) Reset Input Standards

(VCC

= 2.7 V to 3.6 V, VSS = 0.0 V, TA = −40 °C to +85 °C)

*1 : tCP is internal operating clock cycle time. Refer to “ (1) Clock Timing”.

*2 : Oscillator oscillation time is the time to 90

% of amplitude. For a crystal oscillator this is on the order of several

milliseconds to tens of milliseconds. For a ceramic oscillator, this is several hundred microseconds to

several milliseconds. For an external clock signal the value is 0 ms.
