Description
Card Interface
I/O
14
IO
Card I/O: Data signal to/from card. Includes an 11K pull-up
resistor to VCC.
RST
15
O
Card reset: provides reset (RST) signal to card.
CLK
17
O
Card clock: provides clock signal (CLK) to card. The rate of this
clock is determined by the external crystal frequency or
frequency of the external clock signal applied on XTALIN and
CLKDIV selections.
PRES
19
I
Card Presence switch: active high indicates card is present.
Includes a high-impedance pull-down current source.
VCC
18
PSO
Card power supply – logically controlled by sequencer, output of
LDO regulator. Requires an external filter capacitor to the card
GND.
GND
16
GND
–
Card ground.
Host Processor Interface
CMDVCC
6
I
Command VCC (negative assertion): Logic low on this pin
causes the LDO regulator to ramp the VCC supply to the card
and initiates a card activation sequence, if a card is present.
5V/
#V
7
I
5 volt / 3 volt card selection: Logic high selects 5 volts for VCC
and 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 VDD. However, it includes a high
impedance pull-up resistor to default this pin high (selection of
5V card) when not connected. This pin shall not be changed
when
CMDVCC is low.
CLKDIV1
CLKDIV2
20
5
I
Sets the divide ratio from the XTAL oscillator (or external clock
input) to the card clock. These pins include a pull-up resistor for
CLKDIV1 and CLKLDIV2 to provide a default rate of divide by
two.
CLKDIV1
CLKDIV2
CLOCK RATE
0
XTALIN/6
0
1
XTALIN/4
1
XTALIN/2
1
0
XTALIN
OFF
1
O
Interrupt signal to the processor. Active Low - Multi-function
indicating fault conditions and card presence. Open drain output
configuration – It includes an internal 20k pull-up to VDD.
RSTIN
2
I
Reset Input: This signal is the reset command to the card.
I/OUC
3
IO
System controller data I/O to/from the card. Includes an 11K
pull-up resistor to VDD.
