Frequently Asked Questions
What safety protections does the TDA8000 include?
It includes short-circuit, thermal, and card extraction protections, plus enhanced ESD protection (4 kV min) on card connections.
What are the supply voltage and current ratings for the card interface V_CC?
V_CC is regulated to 5 V ±4% (4.8–5.2 V) with a max current of 100 mA.
How should unused I/O lines (I/O1(μC) or I/O2(μC)) be handled?
They must not be left open-circuit; tie them to the CVNC pin if not used.
Which standards does the TDA8000 comply with?
It is approved for ISO 7816 and used in banking, telecom, and pay TV applications.
