Preliminary
LINEAR INTEGRATED CIRCUIT
IC CARD INTERFACE
DESCRIPTION
The UTC UTDA8024 is analog interface IC for 3V or 5V smart
cards. It is placed between the card and the microcontroller to
perform communication, control function, all supply and protection
functions. It requires very few external components for
application. It can be applied in many fields, such as IC card
readers for banking, pay TV, Identification, Electronic payment,
etc.
FEATURES
* Three specifically protected half-duplex bidirectional buffered
I/O lines to card contacts C4, C7 and C8
* Automatic activation and deactivation sequences; initiated by
software or by hardware in the event of a short-circuit, card
take-off, overheating, VDD or VDDP drop-out
* 26MHz integrated crystal oscillator
* DC/DC converter for VCC generation separately powered from a
5 V ± 20% supply (VDDP and PGND)
* 3V or 5V ± 5% regulated card supply voltage (VCC) with
appropriate decoupling has the following capabilities:
- ICC<80mA at VDDP=4~6.5V
- Handles current spikes of 40nAs up to 20MHz
- Controls rise and fall times
- Filtered overload detection at approximately 120mA
* Built-in debounce on card presence contacts
* Supply supervisor for spike-killing during power-on and
power-off and Power-on reset (threshold fixed internally
or externally by a resistor bridge)
* Thermal and short-circuit protection on all card contacts
* Clock generation for cards up to 20MHz (divided by 1, 2, 4 or 8
through CLKDIV1 and CLKDIV2 signals) with synchronous
frequency changes
* Non-inverted control of RST via pin RSTIN
* ISO 7816, GSM11.11 and EMV (payment systems)
Compatibility
* Enhanced ESD protection on card side (>6kV)
* One multiplexed status signal OFF

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. All card contacts are protected against any short-circuit with any other card contact.
