Smart card interface
Product specification
TDA8000; TDA8000T
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.
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”).
