1. The maximum frequency is atFigure3 -6 Defined in.
2. The load capacitance C L must take the capacitance of the PCB and MCU pins into account (the

capacitance of the pins and the circuit board can be roughly estimated as 10 pF).

最大频率条件: (t r + t f ) ≤ (2/3)T 并且 Duty cycle= 50%± 5% (负载电容 CL 在'输入 / 输出交流特性'表格的'条件'一栏中标明)

If the load on the device exceeds Table3-2 Voltage characteristics , Table3-3 Current characteristics withTable3 -4 Thermal characteristics The absolute maximum ratings listed in may cause permanent damage to the device. These values are just rated stresses and do not mean that the device works properly under these conditions. Long-term operation may affect the reliability .

Table3 -4 Thermal characteristics

When the packaged chip is working at the specified working environment temperature, the junction temperature Tj (°C) of the chip table can be calculated according to the following formula:

• Tamb refers to the working environment temperature when the packaged chip is working, the unit is °C;
• θJA refers to the thermal resistance coefficient of the package to the working environment, the unit is °C/W;
• PD is equal to the sum of internal power consumption of the chip and I/O power consumption, and the unit is W. The internal power consumption of the chip is the I DD × V DD of the product . I/O power consumption refers to the power consumption generated by the I/O pins when the chip is working. Usually, the value of this part is very small and can be ignored.

The junction temperature Tj on the table of the chip when the chip is operating at the specified operating ambient temperature must not exceed the maximum junction temperature TJ allowed by the chip.
