Technical information

Figure 7.

T-Flash connection diagram recommendation

(MicroSD Specification Ver 1.0)

Pull-up resistance RDAT and RCMD are implemented to prevent bus floating when no card is

inserted or when all card drivers are in high impedance mode. Resistance values should be

set between 10 k

Ω and 100 kΩ .

The pull-up resistors and capacitors described in the above recommendation are integrated

in the EMIF06-mSD01F2. This makes the EMIF06-mSD01F2 an easy "plug and play"

solution to implement secured T-flash, mini-SD card terminations.
