1. See Figure 14 for capacitor integration.
2. Recommended X7R or X5R ceramic low ESR capacitors, ±15% variation over process, voltage, temperature, and aging.
3. Each V
DD
pin requires both a 47 nF and a 0.01 μF capacitor for high-frequency bypass and EMC requirements.
4. Recommended X7R or X5R ceramic low ESR capacitors, ±15% variation over process, voltage, temperature, and aging.
5. Each V
DDPMC
pin requires both a 47 nF and a 0.01 μF capacitor for high-frequency bypass and EMC requirements.
6. The actual capacitance should be selected based on the I/O usage in order to keep the supply voltage within its operating
range.
7. The recommended flash regulator composition capacitor is 2.0 μF typical X7R or X5R, with -50% and +35% as min and
max. This puts the min cap at 0.75 μF.
8. For noise filtering it is recommended to add a high frequency bypass capacitance of 0.1 μF between V
DDA_EQA/B
and
V
