SAI characteristics

Unless otherwise specified, the parameters given in Table 122 are derived from tests performed under the

ambient temperature, fPCLKx frequency and VDD supply voltage conditions summarized inTable 27, with the

following configuration:

•

Output speed set to OSPEEDRy[1:0] = 10

•

Capacitive load CL = 30 pF

•

Measurement points done at 0.5 × VDD level

•

I/O compensation cell activated

•

HSLV activated when VDD ≤ 2.7 V

•

Voltage scaling range 1

Refer to Table 86. I/O static characteristics for more details on the input/output alternate function characteristics

(SCK, SD, FS).
