4~32GB High Capacity Secure Digital Card

Transcend Information Inc.

Single card capacitance

CCARD

Maximum signal line inductance

fPP ≤ 20 MHz

Pull-up resistance inside card (pin1)

RDAT3

Ω

May be used for card

detection

Note that the total capacitance of CMD and DAT lines will be consist of CHOST, CBUS and one CCARD only because they are

connected separately to the SD Memory Card host.

Host should consider total bus capacitance for each signal as the sum of CHOST, CBUS, and CCARD, these parameters are

defined by per signal. The host can determine CHOST and CBUS so that total bus capacitance is less than the card estimated

capacitance load (CL=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than

maximum value of CL (40 pF).
