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”).
