Power Requirements
To prevent high current conditions due to possible improper sequencing of the power supplies, the connection shown below is
recommended to be made between the DSP56371 IO_VDD and CORE_VDD power pins.
To prevent a high current condition upon power up, the IOVDD must be applied ahead of the CORE VDD as shown below if the
external Schottcky is not used.

Notes:
1. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
thermal resistance.
2. Per SEMI G38-87 and JEDEC JESD51-2 with the single layer board horizontal.
3. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-
883 Method 1012.1).
