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.

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
• Multipurpose card-readers, etc.
