1. The values of Vint(D), Vint(U), Vreset1, and Vreset2 change relative to each other.
2. The Vref input voltage is calculated using the following formula.
Example:
2.7 V (= V
1.5 V (= RAM retention voltage)
Vref1: 2.7 < 3.08 * (Vref1 – 0.1), 3.08 * (Vref1 + 0.1) < 5.5 → 0.98 < Vref1 < 1.68
Vref2: 2.7 < 3.33 * (Vref2 – 0.1), 3.33 * (Vref2 + 0.1) < 5.5 → 0.91 < Vref2 < 1.55
Vref3: 1.5 < 1.91 * (Vref3 – 0.1), 1.91 * (Vref3 + 0.1) < 5.5 → 0.89 < Vref3 < 2.77
Vref4: 2.7 < 2.76 * (Vref4 – 0.1), 2.76 * (Vref4 + 0.1) < 5.5 → 1.08 < Vref4 < 1.89
