10. Power Modes
The CP2200/1 has four power modes that can be used to minimize overall system power consumption. The power
modes vary in device functionality and recovery methods. Each of the following power modes is explained in the
following sections:
Normal Mode (Device Fully Functional)
Link Detection Mode (Transmitter Disabled)
Memory Mode (Transmitter and Receiver Disabled)
Shutdown Mode (Oscillator Output Disabled)
The power modes above are achieved by disabling specific primary functions of the CP2200/1. Figure 15 shows
how power is distributed throughout the CP2200/1. To further reduce power consumption in any of the power
modes, secondary device functions may be turned off individually. The secondary device functions that may be
turned off are:
Link/Activity LED Drivers
Weak pull-ups to VDD
VDD Monitor
