3.1 Power Domains
The OMAP35 30/25 device integrates enhanced features that dynamically adapt energy consumption
according to application needs and performance requirements.
The OMAP35 30/25 device includes an enhanced power-management scheme based on:
• Nine independent functional voltage domains on chip partitioning
• Multiple voltage domains
• Voltage scaling support
• Enhanced memory retention support
• Optimized device off mode
• Centralized management of power, reset, and clock
The external power supplies of OMAP35 30/25 are:
• vdd_mpu _iva for the ARM and IVA2.2 processors
• vdd_core for macros
• vdds for IO macros
• vdds_mem for memory macros
• vdds_sram for SRAM LDOs
• vdds_dpll_dll for DLL IO
• vdds_dpll_per for peripheral DPLLs
• vdds_wkup_bg for wakeup LDO and VDDA (2 LDOs: SRAM and BandGap)
• vdda_dac for video DAC
• vdds_mmc1 and vdds_mmc1a for MMC IO
• The supply voltages are detailed in Table 3-3.
Figure 3-1 illustrates the power domains:
