Electrical characteristics

5.3.27

SD/SDIO MMC card host interface (SDIO) characteristics

Unless otherwise specified, the parameters given in Table 88 are derived from tests

performed under ambient temperature, fPCLKx frequency and VDD supply voltage conditions

summarized in Table 14 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: 0.5VDD

Refer to Section 5.3.16: I/O port characteristics for more details on the input/output

characteristics.
