Power Requirements for OMAP-L138
  Pin Name Voltage (V) Imax (mA) Tolerance Sequencing Order Timing Delay Comments
I/O RTC_CVDD 1.2 1 -25%, +10% 11 n/a  
Core CVDD 1.0 / 1.1 / 1.2 600 -9.75%, +10% 2 n/a  
I/O VDDARNWA. VDDARNW1, PLL0_VDDA, PLL1_VDDA, SATA_VDD, USB_CVDD, USB0_VDDA12 1.2 250 -5%, +10% 3 n/a  
I/O USB0_VDDA18, USB1_VDDA18, DDR_DVDD18, SATA_VDDR, DVDD18 1.8 180 ±5% 4 n/a  
I/O USB0_VDDA33, USB1_VDDA33 3.3 24 ±5% 5 n/a  
I/O DVDD3318_A, DVDD3318_B, DVDD3318_C 1.8 / 3.3 50 / 90 4 ±5% 4 / 5 n/a  

* Notes:
1) If RTC is not used/maintained on a separate supply, it can be included in the STATIC12 (fixed 1.2V) group.
2) If using CVDD at fixed 1.2V, all 1.2V rails may be combined.
2) If 1.8V LVCMOS is used, power rails up with the 1.8V rails. If 3.3V LVCMOS is used, power it up with the ANALOG33 rails (VDDA33_USB0/1)
3) There is no specific required voltage ramp rate for any of the supplies LVCMOS33 never exceeds STATIC18 by more than 2 volts.
4) If DVDD3318_A, B, & C are powered independently, max power for each rail will be 1/3 the above max power.
