ST8024L
Overview
- Designed to be compatible with the NDS conditional access system (except ST8024LTR)
- ISO 7816, GSM11.11 and EMV 4.2 (payment systems) compatible SO-28 TSSOP-20 TSSOP-28
- IC card interface
- 3 V or 5 V supply for the ST8024L device (VDD)
- Three specifically protected half-duplex bi-directional buffered I/O lines to card contacts C4, C7 and C8
- Step-up converter for VCC generation separately powered by a 5 V ± 20% supply (VDDP and PGND)
- 1.8 V ± 6.5%, 3 V or 5 V ± 5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities: - ICC < 80 mA at VDDP = 4.75 to 6.5 V - Handles current spikes of 40 nA up to 20 MHz - Controls rise and fall times - Filtered overload detection at ~120 mA
- Enhanced ESD protection on card side (>6 kV)
- 26 MHz integrated crystal oscillator
- Built-in debounce on card presence contacts
