Overview
INTEGRATED CIRCUITS DATA SHEET TDA8000; TDA8000T Smart card interface Product specification Supersedes data of 1995 Feb 01 File under Integrated Circuits, IC02 1996 Dec 12 Philips Semiconductors Product specification Smart card interface FEATURES • Two protected I/O lines • VCC regulation (5 V ±4%, 100 mA max.
with controlled rise and fall times) • VPP generation (12.
5, 15 or 21 V ±2.
5%, 50 mA max.
programmable by two bits, with controlled rise and fall times) • Clock generation (up to 8 MHz) • Short-circuit, thermal and card extraction protections • Two voltage supervisors (digital and analog supplies) • Automatic activation and deactivation sequences via an independent internal clock • Enhanced ESD protections on card connections (4 kV min.
) • ISO 7816 approval.
APPLICATIONS • Pay TV • Telematics • Cashless payment TDA8000; TDA8000T • Multipurpose card-readers, etc.
GENERAL DESCRIPTION The TDA8000 is a complete, low-cost analog interface which can be positioned between a smart card or a memory card (ISO 7816) and a microcontroller.
It is approved for banking, telecom and pay TV applications.
The complete supply, protection and control functions are realized with only a few external components, which makes the TDA8000 very attractive for consumer applications.
Application suggestions and support is available on request (see examples in Chapter “Application information”).
