Product Description
DESCRIPTION:
- The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 or 5 V smart cards. It can be placed between the card and the microcontroller to perform all supply, protection and control functions. Very few external components are required.
- The TDA8024AT is a direct replacement for the TDA8004AT.

FEATURES:
•IC card interface
•3 or 5 V supply for the IC (VDD and GND)
•Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8
•DC/DC converter for V CC generation separately powered from a 5 V ± 20% supply (VDD and PGND)
•3or5V ±5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:
–ICC< 80 mA at VDDP= 4 to 6.5 V
– Handles current spikes of 40 nAs up to 20 MHz
– Controls rise and fall times
– Filtered overload detection at approximately 120 mA
•Thermal and short-circuit protection on all card contacts
•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
•Enhanced ESD protection on card side (>6 kV)
•26 MHz integrated crystal oscillator
APPLICATIONS:
•IC card readers for banking
•Electronic payment
•Identification
•Pay TV
