ST8024CDR

ST8024CDR is a smartcard interface. It is a complete low-cost analogue interface for asynchronous 3V and 5V smart cards. It can be placed between the card and the microcontroller with a few external components to perform all supply protection and control functions. It is a direct replacement of ST8004. It is used in applications such as smart card readers for set-top-box, IC card readers for banking, identification, and pay TV.

• Designed to be compatible with the NDS conditional access system, IC card interface
• 3V or 5V supply for the IC (VDD and GND), thermal and short-circuit protection on all card contacts
• Controls rise and fall times, filtered overload detection at approximately 120mA
• Enhanced ESD protection on card side (<gt/> 6kV), 26MHz integrated crystal oscillator
• Built-in debounce on card presence contacts, one multiplexed status signal off
• Supply current is 1.2mA maximum at (card inactive, VDD = 3.3V, VDDP = 5V)
• Supply voltage range from 2.7V to 6.5V, total power dissipation is 0.56W maximum
• Clock frequency range from 2.2MHz to 3.2MHz
• Slew rate is 0.15V/µs typical at (VDD = 3.3V, VDDP = 5V, fXTAL = 10MHz)
• Operating temperature range from -25°C to 85°C, SO-28 package
