5.9 External Capacitors
NOTE
• The LCD module is not supported for this family of devices, but the "LCD" name is still
present in some supply voltage or PLL names.
• The ZCE package is not supported for this family of devices.
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.
5.9.1 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 AMIC110 device, because this minimizes the inductance of the circuit board wiring and interconnects.
