Hello,

For example, in MB9BF322LPMC1-G-JNE2, the time from power-on reset to internal reset release is specified as follows.

According to this specification, there is a large gap between the minimum and maximum time values.

What is the cause of this time difference?

Is it due to device-to-device variation?
Is it due to usage environment (temperature, VCC voltage, etc...)?
Or is it any other reason?

Please tell me if there is any information.

Thanks and regards,

Shimamura

Hi Shimamura-san,

Yes, your understanding is correct. It is caused by individual difference and power supply voltage.

Best Regards,
