Power Requirements for OMAP-L137
Core, I/O Pin Name Voltage (V) Imax (mA) Tolerance Sequencing Order Timing Delay
Core CVDD 1.2 600 -5%, +10% 2
PLL0_VDDA, RVDD 1.2 60 -5%, +10% 1
RTC_CVDD 1.2 0.1 -5%, +10% 1
IO USB0_VDDA18, USB1_VDDA18 1.8 50 ±5% 4* Timing on rail not critical. Can be sequenced in any order.
IO DVDD, USB0_VDDA33, USB1_VDDA33 3.3 115 ±5% 3 Must stay below 1.65 V until CVDD has passed 0.9 V.
* No specific sequencing required.

Note:

  1. RTC_CVDD can be combined with PLL & RAM 1.2V supply if desired to turn off RTC when device is off. Otherwise, power RTC_CVDD separately with dedicated power source
