Parameter

Vdet4

Voltage down detection voltage (1)

3.84.4

VCC1=0.8 to 5.5V

NOTES:

1. Vdet4 > Vdet3 > Vdet2.

2. Where reset level detection voltage is less than 2.7 V, if the supply power voltage is greater than the reset level detection voltage, the

operation at f(BCLK)

≤ 10MHz is guaranteed.

3. Vdet3r > Vdet3 is not guaranteed.
