52 / 173 page  TMS570LS3137 SPNS162C – APRIL 2012 – REVISED APRIL 2015 www.ti.com 6 System Information and Electrical Specifications 6.1 Device Power Domains The device core logic is split up into multiple power domains in order to optimize the power for a given application use case. There are 8 core power domains in total: PD1, PD2, PD3, PD4, PD5, RAM_PD1, RAM_PD2 and RAM_PD3. The actual contents of these power domains are indicated in Section 1.4. PD1 is an "always-ON" power domain, which cannot be turned off. Each of the other core power domains can be turned ON/OFF one time during device initialization as per the application requirement. Refer to the Power Management Module (PMM) chapter of TMS570LS31X/21X Technical Reference Manual (SPNU499) for more details. NOTE The clocks to a module must be turned off before powering down the core domain that contains the module. NOTE The logic in the modules that are powered down lose power completely. Any access to modules that are powered down results in an abort being generated. When power is restored, the modules power-up to their default states (after normal power-up). No register or memory contents are preserved in the core domains that are turned off. 52 System Information and Electrical Specifications Copyright © 2012–2015, Texas Instruments Incorporated Submit Documentation Feedback |
