General 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.
Very few external components are required.
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).
- 3 V or 5 V 5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:.
- ICC < 80 mA at VDDP = 4 V to 6.5 V.
- Handles current spikes of 40 nAs up to 20 MHz.
