[quote user="Thomas Hecht"]can I supply the AMIC110 with only one 1.8V voltage comming from one DCDC converter?[/quote] Yes, this is possible, with the exception of VDDS_RTS. See section 6.1 in the datasheet for proper sequencing. [quote user="Thomas Hecht"]whitch are the OPPs that define a common power supply voltage for VDD_MPU and VDD_CORE?[/quote] VDD_CORE power supply can be 1.1V or 0.95V. Since AMIC110 works maximum up to 300MHz, this means that VDD_MPU can also be 1.1V or 0.95V. Furthermore DDR3 is not supported at VDD_CORE = 0.95V, which leaves you with only two possible combinations (Table 5-8). The device should start with both core and MPU at 1.1V. Depending on your power supply solution, after the device boots it is possible to lower VDD_MPU to 0.95V. The AMIC110 EVM uses a PMIC which cannot be regulated, and there is a common 1.1V supply for both VDD_CORE and VDD_MPU. Therefore it's always operating in OPP100.
