UTDA8024
Description
The UTC UTDA8024 is analog interface IC for 3V or 5V smart cards.
Key Features
- Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8
- 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
- Built-in debounce on card presence contacts
- 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) patibility
- Enhanced ESD protection on card side (>6kV)
