4.5
There are two main types of I/O: GPIO and DDR. The DDR pads can be configured in three different
drive-strength modes: MobileDDR, SDRAM, and DDR2. SDRAM and Mobile DDR modes can be further
customized within three drive strength levels: Nominal, High and Max.
Table 13
symbol NVCC refers to the power supply voltage that feeds the I/O of the module in question. For
example, if you are concerned about the SD/MMC interface then NVCC refers to NVCC_SDIO.

Junction-to-Ambient thermal resistance determined per JEDC JESD51-3 and JESD51-6. Thermal test board meets
JEDEC specification for this package.
Junction-to-Board thermal resistance determined per JEDC JESD51-8. Thermal test board meets JEDEC specification
for this package.
Junction-to-Case at the top of the package determined using MIL-STD 883 Method 1012.1. The cold plate temperature
is used for the case temperature. Reported value includes the thermal resistance of the interface layer.
Thermal characterization parameter indicating the temperature difference between the package top and the junction
temperature per JEDEC JESD51-2. When Greek letters are not available, this thermal characterization parameter is
written as Psi-JT.
