SLE5542 Contact Smart Card

SLE5542 Contact Smart Card: Product Overview

The SLE5542 Contact Smart Card is a contact-based memory card designed for secure data storage and identification purposes. It is widely used in systems that require reliable authentication, controlled data access, and long-term stability. With a standardized contact interface, this card integrates easily into existing smart card infrastructures.

Chip & Memory Architecture

The card is powered by an SLE5542 memory IC featuring 256 bytes of EEPROM. The memory is organized to allow byte-level write protection, giving system developers precise control over which data areas can be modified and which must remain permanently locked. This structure supports secure personalization and prevents unauthorized data changes.

Security Features

The SLE5542 smart card includes a programmable security code mechanism that restricts write operations until proper authentication is completed. Once protected, data can only be accessed or modified according to predefined security rules, making the card suitable for controlled-access environments and identity-based applications.
