Electrical characteristics

SPI interface characteristics

Unless otherwise specified, the parameters given in Table 40 are derived from tests

performed under the ambient temperature, fPCLKx frequency and VDD supply voltage

conditions summarized in Table 8.

Refer to Section 5.3.12: I/O port characteristics for more details on the input/output alternate

function characteristics (NSS, SCK, MOSI, MISO).

1. Remapped SPI1 characteristics to be determined.

2. Based on characterization, not tested in production.

3. Min time is for the minimum time to drive the output and the max time is for the maximum time to validate

the data.

4. Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put

the data in Hi-Z
