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. NOTES: 1. All voltage values are with respect to VSS. 2. Actual operating power is less. This value was obtained under specially produced worst-case test conditions for the TMS320C31-33 and the TMS320LC31-40, which are not sustained during normal device operation. These conditions consist of continuous parallel writes of a checkerboard pattern to both primary and extension buses at the maximum rate possible. See normal (ICC) current specification in the electrical characteristics table and also read Calculation of TMS320C30 Power Dissipation Application Report (literature number SPRA020). recommended operating conditions (see Note 3) MIN NOM MAX UNIT VDD Supply voltage (DVDD, etc.) 3.13 3.3 3.47 V VSS Supply voltage (CVSS, etc.) 0 V VIH High-level input voltage (except RESET) 1.8 VDD + 0.3* V VIH High-level input voltage (RESET) 2.2 VDD + 0.3* V VIL Low-level input voltage − 0.3* 0.6 V IOH High-level output current − 300 µA IOL Low-level output current 2 mA TC Operating case temperature −55 125 °C VTH High-level input voltage for CLKIN 2.5 VDD + 0.3* V * This parameter is not production tested. NOTE 3: All voltage values are with respect to VSS. All input and output voltage levels are TTL-compatible. CLKIN can be driven by a CMOS clock. |
