3 ELECTRICAL CHARACTERISTICS
3.1 Power Domains
The OMAP3525 and OMAP3530 devices integrate enhanced features that dynamically adapt energy
consumption according to application needs and performance requirements.
The OMAP3525 and OMAP3530 devices 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 OMAP3525 and OMAP3530 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 for MMC IO
• vpp for eFuse
The supply voltages are detailed in Table 3-3.
