POWER-ON RESET

Reset can be performed automatically during power on (power-on

reset) by the built-in power-on reset circuit. When using this cir-

cuit, set 100 µs or less for the period in which it takes to reach

minimum operation guaranteed voltage from reset.

If the rising time exceeds 100 µs, connect the capacitor between

the RESET pin and VSS at the shortest distance. Consequently,

the RESET pin should be held at “L” until the minimum operation

guaranteed voltage is reached.

Note:

This symbol represents a parasitic diode.

Applied voltage to the RESET pin must be VDD or less.
