SD/SDIO MMC card host interface (SDMMC) characteristics

Unless otherwise specified, the parameters given in Table 113 for the SDIO/MMC interface

are derived from tests performed under the ambient temperature, fPCLK2 frequency and VDD

supply voltage conditions summarized in Table 16, with the following configuration:

•

Output speed is set to OSPEEDRy[1:0] = 11

•

Capacitive load C = 30 pF

•

Measurement points are done at CMOS levels: 0.5VDD

Refer to Section 6.3.20: I/O port characteristics for more details on the input/output

characteristics.
