Electrical characteristics
SAI characteristics
Unless otherwise specified, the parameters given in Table 87 for SAI are derived
from tests performed under the ambient temperature, f_PCLKx frequency and V_DD
supply voltage conditions 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 V_DD
Refer to Section 6.3.14: I/O port characteristics for more details on the input/output
alternate function characteristics (CK,SD,FS).
