[1] This specification applies over the full operating temperature range.
[2] Card side supply voltage.
[3] The enable time is from power-up of V_CC and V_CC2 ≥ 2.7 V to when idle or stop time begins.
[4] Idle time is from when SDAn and SCLn are HIGH after enable time has been met.
[5] I_trt(pu) varies with temperature and V_CC voltage, as shown in Section 11.1 “Typical performance characteristics”.
[6] The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V_CC voltage is shown in Section 11.1 “Typical performance characteristics”.
[7] Guaranteed by design, not production tested.
[8] C_b = total capacitance of one bus line in pF.
