The voltage-management architecture of the device is based on voltage sources managed by the PRCM module. They define the voltage domains within the device (see Section 3.1.1.3, Voltage Management). This partition of the voltage domains ensures independent voltage control of each voltage domain through dedicated LDO. The following voltage domains are managed by the PRCM module:
For the association of the device power supply pin to the power domain, see Table 3-26.
The PRCM module supports the AVS technique on the VDD_MPU_L, VDD_CORE_L, and VDD_IVAHD_L, VDD_DSPEVE_L, VDD_GPU_L, VDD_RTC_L voltage domains.
The PRCM module also supports the ABB technique on the MPU, IVAHD, DSPEVE and GPU voltage domains through the VDD_MPU_ABB and VDD_IVA_ABB, VDD_DSPEVE_ABB, VDD_GPU_ABB biasing voltages.
At boot time, the device is set with all five voltage domains (VDD_MPU_L, VDD_GPU_L, VDD_CORE_L, VDD_DSPEVE_L, VDD_IVAHD_L) at OPP_NOM.
