Electrical characteristics

SPI characteristics

Unless otherwise specified, the parameters given in the following table are derived from

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

conditions summarized in Table 13.

Refer to Section 6.3.12: I/O current injection characteristics for more details on the

input/output alternate function characteristics (NSS, SCK, MOSI, MISO).

1. The characteristics above are given for voltage Range 1.

2. Guaranteed by characterization results.

3. The maximum SPI clock frequency in slave transmitter mode is given for an SPI slave input clock duty

cycle (DuCy(SCK)) ranging between 40 to 60%.

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

data.
