Electrical Specifications
This section provides the absolute maximum ratings and the recommended operating conditions for the
TMS320VC5407/TMS320VC5404 DSP.
5.1 Absolute Maximum Ratings
The list of absolute maximum ratings are specified over operating case temperature. Stresses beyond those
listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under Section 5.2 is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability. All voltage values are with respect to DV . Figure 5−1 provides the test load circuit
SS
values for a 3.3-V device.
