Electrical Specifications

This section provides the absolute maximum ratings and the recommended operating conditions for the

device.

6.1

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 “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions

for extended periods may affect device reliability. All supply voltage (core and I/O) values are with respect to

VSS.

† Texas Instrument DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be

designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage. Excessive

exposure to these conditions can adversely affect the long-term reliability of the devices. System-level concerns such as bus contention may require

supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as or prior to the I/O buffers, and then

powered down after the I/O buffers.
