73S8023C Data Sheet

1 Pin Description

1.1 Card Interface

Name

I/O

Description

Card I/O: Data signal to/from card. Includes a pull-up resistor to V_CC.

AUX1: Auxiliary data signal to/from card. Includes a pull-up resistor to V_CC.

AUX2: Auxiliary data signal to/from card. Includes a pull-up resistor to V_CC.

AUX1

AUX2

RST

CLK

Card reset: Provides reset (RST) signal to card.

Card clock: Provides clock (CLK) signal to card. The rate of this clock is

determined by crystal oscillator frequency and CLKDIV selections.

PRES

VCC

Card Presence switch: Active high indicates card is present. Includes a

pull-down current source.

Card Presence switch: Active low indicates card is present. Includes a pull-up

current source.

Card power supply: Logically controlled by sequencer, output of DC-DC

converter. Requires an external filter capacitor to the card GND.

GND

Card ground.

1.2 Miscellaneous Inputs and Outputs

Name

Description

XTALIN

Crystal oscillator input: can either be connected to crystal or driven as a

source for the card clock.

XTALOUT

VDDF_ADJ

Crystal oscillator output: connected to crystal. Left open if XTALIN is being

used as external clock input.

V_DDfault threshold adjustment input: this pin can be used to adjust V_DDF

value (that controls deactivation of the card). Must be left open if unused.

Non-connected pin. Must be left open.

1.3 Power Supply and Ground

Name

Description

VDD

3, 20

System controller interface supply voltage: Supply voltage for internal power

supply and DC-DC converter power supply source.

GND

LIN

DC-DC converter ground.

Digital ground.

External inductor. Connect external inductor from pin 2 to V_DD. Keep the

inductor close to pin 2.
