Description
Card Interface
I/O
22
14
IO
Card I/O: Data signal to/from card. Includes a
pull-up resistor to VCC.
AUX1
21
N/A
IO
AUX1: Auxiliary data signal to/from card.
Includes a pull-up resistor to VCC.
AUX2
20
N/A
IO
AUX2: Auxiliary data signal to/from card.
Includes a pull-up resistor to VCC.
RST
18
12
O
Card reset: provides reset (RST) signal to card.
RST is the pass through signal on RSTIN.
Internal control logic will hold RST low when
card is not activated or VCC is too low.
CLK
16
10
O
Card clock: provides clock signal (CLK) to card.
CLK is the pass through of the signal on pin
CLKIN. Internal control logic will hold CLK low
when card is not activated or VCC is too low.
PRES
14
8
I
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 current source.
PRES
13
N/A
I
Card Presence switch: active low indicates
card is present. Should be tied to VDD when
not used, but it Includes a high-impedance
pull-up current source.
VCC
19
13
PSO
Card power supply – logically controlled by
sequencer, output of LDO regulator.
Requires an external 0.47
F low ESR filter
capacitor to GND.
GND
17
11
GND
–
Card ground.
Miscellaneous Inputs and Outputs
CLKIN
7
6
I
Clock signal source for the card clock.
TEST1
10
7
–
Factory test pin. This pin must be tied to
GND in typical applications
TEST2
30
20
–
Factory test pin. This pin must be tied to
GND in typical applications
Pow er Supply and Ground
VDD
29
19
PSO
System interface supply voltage and supply
voltage for companion controller circuitry.
Requires a minimum of two 0.1
F capacitors
to ground for proper decoupling.
VPC
26
16
PSI
Power supply source for main voltage
converter circuit. A 10
F and a 0.1F
ceramic capacitor must be connected to this
pin.
