Specifications

5.9

External Capacitors

To improve module performance, decoupling capacitors are required to suppress the switching noise

generated by high frequency and to stabilize the supply voltage. A decoupling capacitor is most effective

when it is close to the device, because this minimizes the inductance of the circuit board wiring and

interconnects.

Voltage Decoupling Capacitors

Table 5-13 summarizes the Core voltage decoupling characteristics.

5.9.1.1

Core Voltage Decoupling Capacitors

To improve module performance, decoupling capacitors are required to suppress high-frequency switching

noise and to stabilize the supply voltage. A decoupling capacitor is most effective when located close to

the AM335x device, because this minimizes the inductance of the circuit board wiring and interconnects.

(1) The typical value corresponds to one capacitor of 10 μF and eight capacitors of 10 nF.

(2) Not available on the ZCE package. VDD_MPU is merged with VDD_CORE on the ZCE package.

(3) The typical value corresponds to one capacitor of 10 μF and five capacitors of 10 nF.
