SAI characteristics
Unless otherwise specified, the parameters given in Table 207 for SAI are derived from tests
performed under the ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized in Table 122: General operating conditions, with the following
configuration:
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Capacitive load CL = 30 pF
•
IO Compensation cell activated.
•
Measurement points are done at CMOS levels: 0.5VDD
•
VOS level set to VOS1.
Refer to Section 7.3.15: I/O port characteristics for more details on the input/output
alternate function characteristics (SCK,SD,WS).
