8.1 Power Supply Mapping

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:

  • Full Active
  • MCU Only low power mode
  • DDR Retention (Suspend-to-RAM or S2R) low power mode
  • MCU Island safety monitor
  • Extended MCU safety monitor

Two power distribution networks (PDNs) that support these different operational modes are recommended and provide optional end product features. To name a few:

  • Dual Voltage (1.8V & 3.3V) IO Interfaces
  • Compliant UHS-I SD Card
  • Compliant USB2.0
  • High Security device type Efuse programming on-board for in-field updates

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:

  • Full device performance entitlement as validated on TI Evalution boards
  • Enable all system functional safety features and analysis captured in device safety manual
  • Support power rail load steps, supply voltage accuracies and maximum load currents with margins
  • Meet device primary & low power mode supply sequencing requirements (refer to Section 6.9.2, Power Supply Sequencing)
  • Provide Adaptive Voltage Scaling (AVS) Class 0 device requirements with TI validated software

  6. VDD_MMC0 is 1.8V digital supply supporting MMC0 signaling for eMMC interface. If MMC0 or eMMC0 interface is not needed, then domain can be grouped with digital IO 1.8V power rail. However, if MMC0 interface is needed, then VDD_MMC0 must not start ramp-up until VDD_CORE has reached Vopr min.
  7. VDD_MCU is a digital voltage supply with a wide operational voltage range and power sequencing flexibility, enabling it to be grouped and ramped-up with either 0.8V VDD_CORE or 0.85V RAM array domains (VDDAR_xxx).
