VDDIO
VDDIO
The High Speed MultiMedia Card Interface (HSMCI) supports the MultiMedia Card (MMC)
Specification V4.3, the SD Memory Card Specification V2.0, the SDIO V2.0 specification and
CE-ATA V1.1.
Timings are given assuming the following VDDIO supply and load.
VDDIO = 1.62V @25pF
from 3.0V to 3.6V, maximum external capacitor = 30 pF.
from 1.65V to 1.95V, maximum external capacitor = 30 pF.
