5.1Major Component Thermal Specifications

Most of the major components used in Tegra 200 series Developer Board are listed in Table 39 along with the temperature range they are able to operate across.

Note: The specifications noted in Table 16 may change and other versions with wider or narrower temperature ranges may be available from the manufacturers

Any design using these components must ensure each of these devices do not exceed the maximum temperature. This may require careful board and mechanical design practices to accommodate various contributors to heat generation.

5.2 Thermal Considerations for Components

Figure 27 and Figure 28 show the top and bottom of the Tegra 200 Series Developer Board. The components that either generate heat, or may be very sensitive to temperature are highlighted with different colors:

ƒGreen: Adversely sensitive to heat

ƒYellow: Mild contributor to heat generation

ƒLt Orange: Medium contributor to heat generation

ƒDark Orange: Significant contributor to heat generation

The Green coded devices may be significantly affected by temperature. Typically these have more analog circuitry and may not perform as well hot such as the Camera Module. The other highlighted parts contribute additional heat to the system which can be problematic to deal with in an enclosed mobile device.
