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 Schottky is not used.

Note:
1. GND = 0 V; TJ = –40°C to 115°C for 150 MHz; TJ = 0°C to 100°C for 181 MHz; CL = 50PF
2. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress
beyond the maximum rating may affect device reliability or cause permanent damage to the device.
3. Operating temperature qualified for automotive applications.
