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.
• 100% Compatible with ISO 7816–3 Standard
• Wide Battery Supply Voltage Range: 1.8V < VBAT < 6.6V
• Programmable VCC Supply for 3V or 5V Card Operation
• Power Management for Very Low Quiescent Current in Stand By
Mode (30µA max)
• Microprocessor Wake–up Signal Generated Upon Card Insertion
• Self Contained DC/DC Converter to Generate VCC using a Minimum
of Passive Components
• Controlled Power Up/Down Sequence for High Signal Integrity on
the Card I/O and Signal Lines
• Programmable Card Clock Generator
• Chip Select Capability for Parallel Coupler Operation
• High ESD Protection on Card Pins (4kV, Human Body Model)
• Fault Monitoring VBATlow, VCClow and ICClim
• All Card Outputs Current Limited and Short Circuit Protected
• Tested Operating Temperature Range: –25°C to +85°C
