Table 51. I/O AC characteristics (continued)

1. The fall time is defined between 70% and 30% of the output waveform, according to I 2 C specification.
2. This value represents the I/O capability but the maximum system frequency is limited to 48 MHz.

1. Refer to Table 51: I/O AC characteristics .

Stresses above the absolute maximum ratings listed in Table 20 , Table 21 and Table 22 may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. The device mission profile (application conditions) is compliant with the JEDEC JESD47 qualification standard.

All voltages are defined with respect to V SS .

Table 22. Thermal characteristics

The operating junction temperature T J must never exceed the maximum given in Table 23: General operating conditions .

The maximum junction temperature in °C that the device can reach if respecting the operating conditions, is:

$$T_J(max) = T_A(max) + P_D(max) \times \Theta_{JA}$$

In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance. ECOPACK specifications, grade definitions and product status are available at: www.st.com . ECOPACK is an ST trademark.
