TDA8024 Overview
Description
The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 V or 5 V smart cards. It can be placed between the card and the microcontroller to perform all supply, protection and control functions.
Key Features
- IC card interface
- 3 V 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-to-DC converter for VCC generation separately powered from a 5 V 20% supply (VDDP and PGND)
- Thermal and short-circuit protection on all card contacts
- Enhanced ESD protection on card side (>6 kV)
- 26 MHz integrated crystal oscillator
- Clock generation for cards up to 20 MHz (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 NXP Semiconductors TDA8024 Standard sma
