Hello.

Does S29AL016J70TFI020 has Power-On-Reset function?

If VCC pin and Reset pin are shorted(So a timing of power-on and power-off of VCC pin and Reset pin are same), is S29AL016J70TFI020 reset correctly?

Voltage level of VCC pin and Reset pin is 3.3V.

Or is there power sequence because S29AL016J70TFI020 does not Power-On-Reset function?

For example, Reset pin should be low revel until VCC pin completely power on, etc

Best Regards.

Hello Matsubara-san,

The power up sequence for the AL-J part is very simple.

Therefore, your S29AL016J70TFI020 part will work with VCC directly connected to the RESET# signal.

That will result in a correct power up reset sequence which just requires the user to wait tVCS (50us) after VCC ramp-up to your 3.3V level.

Best regards,

Bacem
