TDA8000/TDA8000T is a smart card interface chip produced by Philips company, which has VCC voltage regulation, VPP voltage generation, clock generation, short-circuit, thermal and card extraction protection, two voltage supervisors, automatic activation and deactivation sequence, and enhanced ESD protection. Suitable for banking, telecommunications and pay TV applications.
The Philips TDA8000 is a complete, low-cost analog interface designed to position between a smart or memory card (ISO 7816) and a microcontroller. It is approved for banking, telecom, and pay TV applications, requiring only a few external components for supply, protection, and control functions.
The device supports two protected I/O lines and programmable programming voltage generation (Vpp) of 12.5, 15, or 21 V. It includes automatic activation and deactivation sequences via an internal clock, along with short-circuit, thermal, and card extraction protections.
