CARD VCC AND CARD CLOCK PROGRAMMING
The CRDVCC and ASYCLK programming options allow the system clock frequency to be matched to the card clock
frequency and to select 3.0 V or 5.0 V CRDVCC supply. Table 3 shows the values of PWRON, RESET and I/O for the possible
options. The default power reset condition is state 4 (synchronous clock and CRDVCC =5.0 V). All states are latched for each
output variable in programming mode at the positive transition of CS (Figure 20).

NOTE:
Card clock integrity is maintained during all frequency commutations (no spikes).
State 4 is the default state at power on.
DCDC CONVERTER AND CARD DETECTOR STATUS
The MC33560 status can be polled when CS = L. Please
consult Table 2 for a description of input and output
signals.The significance of the status message is described
in Table 4.

DETAILED OPERATING DESCRIPTION
INTRODUCTION
The MC33560 Smartcard interface IC has been designed
to provide all necessary functions for safe data transfers
between a microcontroller and a smartcard or memory card.
A card detector scans for the presence of a card and
generates
a
debounced
wakeup
signal
to
the
microcontroller.
Communication and control signal levels are translated
between the digital interface and the card interface by the
voltage level translator, and the card clock is matched to the
system clock frequency by the programmable card clock
generator. The power management unit enables the DCDC
converter
for
card
power
supply,
supervises
the
powerup/down sequence of the card’s I/O and signal lines,
and keeps the power consumption very low in standby
mode.
All card interface pins have adequate ESD protection, and
fault monitoring (VBATlow, VCClow, ICClim) guarantees
hazard free card reader operation.
Several MC33560s can be operated in parallel, using the
same control and data bus, through the use of the chip select
signal CS.
