16 / 32 page ![]() Electrical characteristics STWBC-EP 16/32 DocID030747 Rev 1 6.8 Absolute maximum ratings Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only and the functional operation of the device under these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect the device reliability. Table 3. Voltage characteristics Symbol Ratings Min. Max. Unit VDDX - VSSX Supply voltage(1) 1. All power VDDX (VDD, VDDA) and ground VSSX (VSS, VSSA) pins must always be connected to the external power supply. -0.3 6.5 V VIN Input voltage on any other pin(2) 2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive injection is induced by VIN > VDD while a negative injection is induced by VIN < VSS. VSS -0.3 VDD +0.3 VDD - VDDA Variation between different power pins - 50 mV VSS - VSSA Variation between all the different ground pins(3) 3. VSS and VSSA signals must be interconnected together with a short wire loop. -50 mV Table 4. Current characteristics Symbol Ratings Max.(1) 1. Data based on characterization results, not tested in production. Unit IVDDX Total current into VDDX power lines(2) 2. All power VDDX (VDD, VDDA) and ground VSSX (VSS, VSSA) pins must always be connected to the external power supply. 100 mA IVSSX Total current out of VSSX power lines(2) 100 IIO Output current sunk by any I/Os and control pin Ref. to Table 10 on page 21 Output current source by any I/Os and control pin - IINJ(PIN)(3), (4) 3. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive injection is induced by VIN > VDD while a negative injection is induced by VIN < VSS. 4. Negative injection disturbs the analog performance of the device. Injected current on any pin ±4 IINJ(TOT) (3),(4), (5) 5. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the positive and negative injected currents (instantaneous values). These results are based on characterization with IINJ(PIN) maximum current injection on four I/O port pins of the device. Sum of injected currents ±20 Table 5. Thermal characteristics Symbol Ratings Max. Unit TSTG Storage temperature range -65 to 150 ºC TJ Maximum junction temperature 150 |
