PRODUCTION DATA
The device supports two unique power topologies for BOM optimized and Power Optimized modes. Above tables from Section 7.6.1 to Section 7.6.4 summarize these options. Based on whether the 1.2V rail is generated internally or is provided from external source, two power topologies comes into account.
In BOM optimized mode the device can be powered up using one rail (1.8V) or two rails (3.3V and a 1.8V) provided externally. The 1.2V rail is internally generated in BOM optimized topology.
In power optimized mode, the device can either be powered using two rails (1.8V and 1.2V) or with three rails (3.3V, 1.8V and 1.2V), all provided externally. The 1.2V rail is NOT internally generated in Power optimized topology. The device senses the external 1.2V supply and decides which topology the device will operate on.
