RX111 Group 5. Electrical Characteristics
Figure 5.6 Ripple Waveform
Note: • The recommended capacitance is 4.7 μF. Variations in connected capacitors should be within the above range.
Table 5.14 DC Characteristics (12)
Conditions: VCC = AVCC0 = VCC_USB = 1.8 to 3.6 V, VSS = AVSS0 = VREFL0 = VSS_USB = 0 V, T
a
= –40 to +105°C
The ripple voltage must meet the allowable ripple frequency f
r(VCC)
within the range between the VCC upper limit
(3.6 V) and lower limit (1.8 V).
When VCC change exceeds VCC ±10%, the allowable voltage change rising/falling gradient dt/dVCC must be met.
