Table 2: 73S8014R/RN/RT Pin Description: Card Interface
Description
Card I/O: Data signal to/from card. Includes a pull-up resistor to V
Card reset: provides reset (RST) signal to card.
Card clock: provides clock signal (CLK) to card. The rate of this clock is
determined by crystal oscillator frequency or external clock input and CLKDIV
selections.
Card Presence switch: active high indicates card is present. Should be tied
to GND when not used, but it Includes a high-impedance pull-down resistor.
Description
Description
Card power supply – logically controlled by sequencer, output of LDO
regulator. Requires an external filter capacitor to the card GND.
Card ground
Crystal oscillator input: can either be connected to the crystal or driven as a
source for the card clock.
Crystal oscillator output: connected to the crystal. Left open if XTALIN is
being used as external clock input.
V
values (that controls deactivation of the card). Must be left open if unused.
System interface supply voltage and supply voltage for internal circuitry.
LDO regulator power supply source.
Digital ground.
DD
fault threshold adjustment input: this pin can be used to adjust the V
