Our customer wants to start designing a prototype board with the AM6442 SR1.0.
The following application note provides a solution using one or two PMICs.
Powering the AM64xx With the LP8733xx PMIC
www.ti.com/.../slvaes0.pdf
Can the one PMIC solution be applied for AM6442 SR1.0?
Can the one PMIC solution be applied when using two 8-Bit DDR4 devices?
Our customer may use the two PMIC solution because they want to use multiple Ethernet with both CPSW3G and PRU_ICSSG.
Can the two PMIC solution be applied for AM6442 SR1.0?
TPS6521855 needs to be reprogrammed for DDR4 memory use.
Is there a TPS65218xx programmed for DDR4 memory? If so, what is the part number?
Can the two PMIC solution be applied when using two 8-Bit DDR4 devices?
The VPP rail of the DDR4 memory can be supplied 2.5 V by DCDC4 of the TPS6521855.
Can the VDDS_DDR and the VDD/VDDQ rail of the DDR4 memory be supplied 1.2 V by DCDC1 of the TPS6521855.
Does the VTT rail of the DDR4 memory need to be supplied by adding TPS51206?
What other differences are there between using DDR4 and LPDDR4 in the two PMIC solution?
