CRDCON
INPUT high
impedance
This pin connects to PGND or VBAT, or possibly to an output port of the microcontroller. With
this pin set to a logic “0”, the presence of a card is signalled with a logic ”1” on pin 17. With
this pin set to a logic ”1”, the presence of a card is signalled with a logic ”0” on pin 17.

CRDC8
I/O
General purpose input/output. It has the same behavior as CRDIO. It can be connected to the
C8 pin of the card connector

CRDGND using appropriate grounding techniques.
CURRENT LIMIT AND THERMAL PROTECTION
1
PGND
POWER
This pin is the return path for the current flowing into pin 22 (L1). It must be connected to
12
CRDGND
POWER
This pin is the signal ground. It must be connected to the ground pin of the card connector. It
is the reference level for all analog and digital signals.
13
CRDVCC
POWER
This pin connects to the VCC
pin of the card connector. It is the reference level for a logic ”1”
of pins 11, 14, 15, 16 and 19.
22
L1
POWER
This pin connects to an external inductance for the DC/DC converter. Please refer to the
description of the DC/DC converter functional block.
23
VBAT
POWER
This pin is connected to the supply voltage. Logic level ”1” of pins 2 to 10, 17, 18, 20 and 21 is
referenced to VBAT. Operation of the MC33560 is inhibited when VBAT
is lower than the
minimum value.
24
ILIM
POWER
This pin can be connected to the PGND pin, or to a resistor connected to PGND, or left open,
depending on the peak coil current needed to supply the card.
PROGRAMMING AND STATUS FUNCTIONS
The MC33560 features a programming interface and a status interface. Figure 20 shows how to enter and exit programming
mode; table 2 shows which pins are used to access the various functions.
