5 Electrical Specifications
This section provides the absolute maximum ratings and the recommended operating conditions for the
TMS320VC5510 DSP.
All electrical and switching characteristics in this data manual are valid over the recommended operating
conditions unless otherwise specified.
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” (Section 5.2) 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 “recommended operating conditions” (Section 5.3) is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability. All supply voltage
values (core and I/O) are with respect to V_SS. Figure 5−1 provides the test load circuit values for a 3.3-V
device. Measured timing information contained in this data manual is based on the test load setup and
conditions shown in Figure 5−1.
