TDA8000 Description
The TDA8000 is a plete, 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, tele and pay TV applications. The plete supply, protection and control functions are realized with only a few external ponents, which makes the TDA8000 very attractive for consumer applications.
TDA8000 Key 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
