MC33560
Power Management and
Interface IC for Smartcard
Readers and Couplers
The MC33560 is an interface IC for smartcard reader/writer
applications. It enables the management of any type of smart or memory
card through a simple and flexible microcontroller interface. Moreover,
several couplers can be coupled in parallel, thanks to the chip select input
pin (pin #5). The MC33560 is particularly suited to low power and
portable applications because of its power saving features and the
minimum of external parts required. Battery life is extended by the wide
operating range and the low quiescent current in stand by mode. A highly
sophisticated protection system guarantees timely and controlled
shutdown upon error conditions.

Note 3: Maximum thermal rating beyond which damage to the device may occur
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However precautions must be
taken to avoid applications of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation, input
and output voltages should be constrained to the ranges indicated in the recommended operating conditions.
ELECTRICAL CHARACTERISTICS These specifications are written in the same style as common for standard
integrated circuits. The convention considers current flowing into the pin (sink current) as positive and current flowing out of the pin
W(source current) as negative. (Conditions: VBAT = 4V, VCC = 5V nom, PWRON = VBAT , operating mode, –ICC = 10mA, –25°C TA
85°C, L1 =47µH, RLIM =0 , CRDVCC capacitor=10µF, unless otherwise noted.)
