AC Characteristics
(1) Reset Timing
(VCC
= +3.0 V±10% for MB89163L/165L; +5.0 V±10% for MB89PV160/P165/W165, VSS = 0.0 V, Ta = –40°C to +85°C)
Notes :
tHCYL is the main clock oscillator period.
If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause
malfunctions. Use caution so that the reset pulse less than the specifications will not be fed to the external
reset pin (RST) .
(2) Power-on Reset
(VSS = 0.0 V, Ta = –40
°C to +85°C)
Note : Make sure that power supply rises within the selected oscillation stabilization time. If power supply voltage
needs to be varied in the course of operation, a smooth voltage rise is recommended.
