This Jacinto 7TM processor device can be operated in several different modes of operation depending upon the number of power resources, power supply groups (i.e. power rails) and control signals available:
Two power distribution networks (PDNs) that support these different operational modes are recommended and provide optional end product features. To name a few:
An Isolated PDN provides independent MCU & Main power resources & rails (see Table 8-2) to support power rail Freedom From Interference (FFI) as desired to reach end product system functional safety targets. An isolated PDN is needed to support MCU Only lower power mode or MCU Island safety monitoring. MCU ONLY can significantly reduce device power by disabling all Main processing while only keeping MCU processor resources active. A Combined PDN reduces total number of power resources & rails by grouping MCU & Main supplies into common power rails (see Table 8-1). This PDN can be used for Extended MCU safety processing but does not allow for MCU Island safety monitor or MCU Only low power modes. The DDR Retention low power mode can be supported with either an Isolated or Combined PDN scheme.
The TPS6594x & LP8764x Power Management ICs (PMICs) are key power components in the two recommended PDNs. Additional discrete power components may be added as desired to support optional system features. TI has optimized recommended PDNs using these PMICs for the following reasons:
