SLLSES1D December 2015 – September 2020 HD3SS3220
PRODUCTION DATA
The HD3SS3220 can be configured as a DFP, UFP, or DRP using the 3-level PORT pin. The PORT pin should be strapped high to VDD5 using a pull-up resistance to achieve DFP mode, low to GND for UFP mode or left floating for DRP mode on the PCB. This flexibility allows the HD3SS3220 to be used in a variety of applications. The HD3SS3220 samples the PORT pin after reset and maintains the desired mode until the HD3SS3220 is reset again. It shall be static. Table 7-1 shows the supported features in each mode.
