This document describes the features of the Security & Chip Card ICs Eurochip 77 SLE 7736 and SLE 7736E, including high security authentication and card-trash mechanism.
The SLE 7736/36E is an intelligent EEPROM counter designed for prepaid telephone cards and pay TV applications. It features 221 bits of EEPROM, 16-bit mask-programmable ROM, and security functions including authentication and card-trash mechanisms. The chip supports up to 33,352 count units with counter tearing protection and operates in a temperature range of -40°C to +80°C. It is compatible with the Eurochip family and can be used in both wire-bonded module and die formats.
The chip includes a secure authentication unit with challenge-response procedures, a card-trash mechanism for physical devaluation, and advanced security features such as EEPROM security cells and shielding. It is available in multiple voltage ranges and packaging options, including M3 module and die formats, for embedding in plastic cards or customer packaging.
