† 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.

† 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 (and

powered down after), the I/O buffers. For additional power sequencing information, see the Power Supply Sequencing Solutions for Dual Supply

Voltage DSPs application report (literature number SLVA073).

‡ On the VC549 devices, the following pins have schmitt trigger inputs: RS, INTn, NMI, X2/CLKIN, CLKMDn, TCK, HAS, HCS, HDSn, BCLKRn,

TCLKR, BCLKXn, and TCLKX

See Figure 1 for 3.3-V device test load circuit values.
