132 / 265 page  OMAP3530, OMAP3525 SPRS507H – FEBRUARY 2008 – REVISED OCTOBER 2013 www.ti.com 3.6.2 Power-down Sequence The following steps give an example of the power-down sequence supported by the OMAP3530/25 device. 1. Reset OMAP3530/25 device. 2. Stop all signals driven to OMAP3530/25 balls. 3. Option 1: Power down all domains simutaneously. 4. Option 2: If all domains cannot be powered down simultaneously, follow the below sequence: (a) Power off all complex I/O domains (vdds_mmc1, vdds_mmc1a, vdda_dac) (b) Power off all core domains (vdd_core, vdd_mpu _iva) (c) Power off all PLL domains (vdds_dpll_dll, vdds_dpll_per) (d) Power off all SRAM LDOs (vdds_sram) (e) Power off all reference domains (vdds_wkup_bg) (f) Power off all standard I/O domains (vdds, vdds_mem) The OMAP3530/25 device proceeds with the power-down sequence shown in . Note: Another possible power-down sequence: • vdd_mpu _iva shuts down before vdd_core. • vdds_sram, vdds_wkup_bg, vdds, and vdds_mem shut down simultaneously. • vdds_dpll_dll and vdds_dpll_per shut down anytime between all complex IO domains shut down and vdds_sram shuts down. 132 ELECTRICAL CHARACTERISTICS Copyright © 2008–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP3530 OMAP3525 |
