SAI characteristics

Unless otherwise specified, the parameters given in Table 98 for SAI are derived from tests

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

tions summarized inTable 22: General operating conditions, with the following configuration:

•

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

•

Capacitive load C = 30 pF

•

Measurement points are done at CMOS levels: 0.5 ₓ VDD

Refer to Section 6.3.14: I/O port characteristics for more details on the input/output alternate

function characteristics (CK,SD,FS).
