Table 2.10

Rising and falling gradient and ripple frequency characteristics

The ripple voltage must meet the allowable ripple frequency fr(VCC) within the range between the VCC upper limit (3.6 V) and lower limit (2.7

V). When the VCC change exceeds VCC ±10%, the allowable voltage change rising and falling gradient dt/dVCC must be met.
