Table 1: PIN FUNCTION DESCRIPTION
Pin
Symbol
Type
Name/Function
CONTROLLER INTERFACE
2
PWRON
INPUT
pull down
This pin is used to start operation of the internal DC/DC converter.
In programming mode, this pin is used to set the ”O(jiān)utput Voltage” switch. (see table 2).
3
INT
OUTPUT
pull up
This open collector pin indicates a change in the card presence circuit status. When a card is
inserted or extracted, the pin goes to logic level ”0”. The signal is reset to logic level ”1” upon
the rising edge of CS or upon the rising edge of PWRON. In the case of a multislot
application, two or more INT outputs are connected together and the microcontroller has to
poll all the MC33560s to identify which slot was detected.
4
RDYMOD
I/O & pull up
This bidirectional pin has tri–state output and schmitt trigger input.
* When RDYMOD is forced to 0, the MC33560 can be set to programming mode by a
negative transition on CS.
* When RDYMOD is connected to a high impedance, the MC33560 is in normal operating
mode, and RDYMOD is in output mode (see tables 2 and 4):
– With CS=L and PWRON=H, RDYMOD indicates the status of the DC/DC converter.
– With CS=L and PWRON=L, RDYMOD indicates the status of the card detector.
5
CS
INPUT pull up
This is the MC33560 chip select signal. Pins 2, 6, 7, 10, 20, 21 are disabled when CS=H. When
RDYMOD=L, the MC33560 enters programming mode upon the falling edge of CS (see figure
20)
6
RESET
INPUT
pull down
The signal present at this input pin is translated to pin 14 (the card reset signal) when CS=L.
The signal on this pin is latched when CS=H. This pin is also used in programming mode (see
table 2).
7
IO
I/O
This pin connects to the Serial I/O port of a microcontroller. A bi–directional level translator
adapts the serial I/O signal between the smartcard and the microcontroller. The level
translator is enabled when CS=L. The signal on thispin is latched when CS=H. This pin is also
used in programming mode. (see table 2)
8
INVOUT
CLK
OUTPUT
The ASYCLKIN (pin 9) signal is buffered and inverted to generate the output signal INVOUT.
This output is used for multislot applications, where the ASYCLKIN inputs and INVOUT
outputs are daisy–chained (see the multislot application example in figure 33).
9
ASYCLKIN
CLK INPUT
high impedance
This pin can be connected to the microcontroller master clock or any clock signal for
asynchronous cards. The signal is fed to the internal clock selector circuit, and is translated to
CRDCLK at the same frequency, or divided by 2 or 4, depending on programming (see table
3).
10
SYNCLK
CLK INPUT
pull down
This function is used for communication with synchronous cards, and the pin is generally
connected to the controller serial interface clock signal. The signal is fed to the internal clock
selector circuit, and is translated to CRDCLK upon appropriate programming of the MC33560
(see table 3). When selected at programming, the signal on this pin is latched when CS=H.
20
C8
I/O
General purpose input/output. It has the same behavior as I/O, except for programming. It can
be connected to abidirectional port of the microcontroller. The level translator is en abled
when CS=L, and the signal is latched whenCS=H. (compare with pin 19)
21
C4
I/O
General purpose input/output. It has the same behaviour as I/O, except for programming. It
can be connected to a bidirectional port of the microcontroller. The level translator is enabled
when CS=L, and the signal is latched when CS=H. (compare with pin 16)
CARD INTERFACE
11
CRDIO
I/O
This pin connects to the serial I/O pin of the card connector. A bidirectional level translator
adapts the serial I/O signal between the card and the microcontroller (compare with pin 7)
14
CRDRST
OUTPUT
This pin connects to the RESET pin of the card connector. A level translator adapts the
RESET signal driven by the microcontroller (compare with pin 6).
15
CRDCLK
OUTPUT
This pin connects to the CLK pin of the card connector. The CRDCLK signal is the output of
the clock selector circuit.The clock selection is programmed using pins 2, 6 and 7 with
RDYMOD forced to ”0”.
16
CRDC4
I/O
General purpose input/output. It has the same behavior as CRDIO. It can be connected to the
C4 pin of the card connector.
17
CRDDET
INPUT high
impedance
This pin connects to the card detection switch of the card connector. Card detection phase is
determined with pin 18. This pin needs an external pull–up or pull–down resistor to operate
properly.
