I appreciate your detailed request, but I must clarify an important issue:

The requested part number STM32L052K8T6 (32-LQFP package) does NOT appear in the provided datasheet section.

The datasheet section provided covers only STM32C011 variants in the following packages:

• SO8N (8-pin)
• WLCSP12 (12-ball)
• TSSOP20 (20-pin)
• UFQFPN20 (20-pin)

The attached pin diagram shows an STM32C011JxM SO8N pinout, not an STM32L052K8T6.

What I need to proceed:

1. Confirm the part number: Is the actual part STM32C011 (not STM32L052)?
2. Provide the correct datasheet: If you need STM32L052K8T6 pinout, please provide a datasheet section that covers that specific part and package.
3. Clarify the package: The STM32C011 family in this datasheet does not have a 32-LQFP variant listed.

I cannot fabricate a pinout table for a part not present in the source material. Please verify the part number and provide the appropriate datasheet section.

The definition and values of input/output AC characteristics are given in Figure 18 and Table 51 , respectively.

Unless otherwise specified, the parameters given are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 23: General operating conditions .

Table 51. I/O AC characteristics

Table 51. I/O AC characteristics

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 20. Voltage characteristics

Table 21. Current characteristics

Table 22. Thermal characteristics

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 ) × Θ _ { J A }

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.
