1.3 Specification

Table 1-1 summarizes the F28E12x LaunchPad specifications.

Table 1-1 LAUNCHXL-F28E12X Specifications
ParameterValue
Board supply voltage

5VDC from one of the following sources:

  • USB Connector (USB1) - USB Type-C® cable connected to PC or other compatible power source.
  • BoosterPack™ 1
  • Auxiliary power connectors

3.3VDC from one of the following sources:

  • BoosterPack 1

  • Auxiliary power connectors

Dimensions

3.00 in x 2.3 in x 0.925 in (7.62 cm x 5.84 cm x 2.35 cm) (L x W x H)

Break-out power output
  • 3.3VDC to BoosterPacks, limited by output of TPS7A80 LDO. This 3.3V plane is shared with on-board components. Total output power limit of TPS7A80 is 1.0A.
Assumed operating conditionsThis kit is assumed to run at standard room conditions. The EVM can run at approximately standard ambient temperature and pressure (SATP) with moderate-to-low humidity.

Figure 1-1 highlights the key features of the F28E12x LaunchPad.
