Electrical characteristics

10.3.8

SPI serial peripheral interface

Unless otherwise specified, the parameters given in Table 42 are derived from tests

performed under ambient temperature, fMASTER frequency and VDD supply voltage

conditions. tMASTER = 1/fMASTER.

Refer to I/O port characteristics for more details on the input/output alternate function

characteristics (NSS, SCK, MOSI, MISO).

1. Values based on design simulation and/or characterization results, and not tested in production.

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

3. 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.
