MICROCONTROLLER INTERFACE

Name

Description

28SO

20QFN 32QFN

CMDVCC

Command VCC (negative assertion): Logic low on this pin

causes the LDO regulator to ramp the V_CCsupply to the

card and initiates a card activation sequence, if a card is

present.

5V/#V

5 volt / 3 volt card selection: Logic one selects 5 volts for

V_CCand card interface, logic low selects 3 volt operation.

When the part is to be used with a single card voltage,

this pin should be tied to either GND or V_DD. However, it

includes a high impedance pull-up resistor to default this

pin high (selection of 5V card) when not connected.

CLKSTOP

CLKLVL

–

Stops the card clock signal during a card session when

set high (card clock STOP mode). Internal pull-down

resistor allows this pin to be left as an open circuit if the

clock STOP mode is not used.

Sets the logic level of the card clock STOP mode when

the clock is de-activated by setting pin 7 high. Logic low

selects card STOP low. Logic high selects card STOP

high. Internal pull-down resistor allows this pin to be left

as an open circuit if the clock STOP mode is not used.

CLKDIV1

CLKDIV2

Sets the divide ratio from the XTAL oscillator (or external

clock input) to the card clock. These pins include

pull-down resistors.

CLKDIV1

CLKDIV2

CLOCK RATE

XTALIN/8

XTALIN/4

XTALIN/2

XTALIN

OFF

Interrupt signal to the processor. Active Low - Multi-

function indicating fault conditions and card presence.

Open drain output configuration. It includes an internal

21kΩ pull-up to V_DD.

RSTIN

I/OUC

Reset Input: This signal is the reset command to the card.

System controller data I/O to/from the card. Includes a

pull-up resistor to V_DD.

AUX1UC

AUX2UC

–

System controller auxiliary data I/O to/from the card.

Includes a pull-up resistor to V_DD.

System controller auxiliary data I/O to/from the card.

Includes a pull-up resistor to V_DD.
