Electrical Specifications

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

TMS320VC5509 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” 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 VSS. Figure 5−1 provides the test load circuit

values for a 3.3-V I/O.

† The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered down.

Due to the fact that different voltage devices can be connected to the I2C bus, the level of logic 0 (low) and logic 1 (high) are not fixed and

depends on the associated VDD.

‡ USB I/O pins DP and DN can tolerate a short circuit at D+ and D− to 0 V or 5 V, as long as the recommended series resistors (see Figure 5−40)

are connected between the D+ and DP (package), and the D− and DN (package). Do not apply a short circuit to the USB I/O pins DP and DN

in absence of the series resistors.

NOTE: USB PLL is powered from the core supply and is susceptible to core power supply ripple. The maximum allowable supply ripple is 1%

for 1 Hz to 5 kHz; 1.5% for 5 kHz to 10 MHz; 3% for 10 MHz to 100 MHz, and less than 5% for 100 MHz or greater.
