13 Enhanced Secure Digital Host Controller (eSDHC)

This section describes the DC and AC electrical specifications for the eSDHC (SD/MMC/SDIO) interface

of the MPC8308.

The eSDHC controller always uses the falling edge of the SD_CLK in order to drive the

SD_DAT[0:3]/CMD as outputs and rising edge to sample the SD_DAT[0:3], CMD, CD, and WP as inputs.

This behavior is true for both full- and high-speed modes.

eSDHC DC Electrical Characteristics

Table 38 provides the DC electrical characteristics for the eSDHC (SD/MMC) interface of the device,

compatible with SDHC specifications. The eSDHC NVDD range is between 3.0 V and 3.6 V.
