Descripción

The Infineon SLE4442/SLE5542 is a reliable and secure memory smart card chip designed for applications requiring long-term data protection and precise control. Equipped with 256 × 8-bit EEPROM and 32-bit protected memory, it provides reliable storage performance and strong data security for loyalty cards, hotel key systems, fuel management, and access control solutions.

The chip supports byte-level erase and write operations for flexible data management. At the same time, the PROM function provides irreversible write protection for the first 32 bytes, making it ideal for protecting sensitive information such as card numbers or authentication data. The SLE4442/SLE5542 complies with the ISO 7816 standard and integrates seamlessly with most existing contact smart card readers and personalization systems.

With over 100,000 read and write cycles and eight years of data retention, the chip ensures stable and long-lasting performance even under heavy use. The chip adopts the CR80 standard card specification (86×54 mm) and can be made of PVC, PET, PET-G, or PC materials, flexibly meeting various environmental and durability requirements.

FAQ

1. What makes the Infineon SLE4442 suitable for secure data storage?
The SLE4442 includes a 32-bit protection memory that provides permanent write protection (PROM) for critical data areas. This prevents any unauthorised modification, ensuring long-term data integrity and reliability in sensitive applications.

2. Can the SLE4442 chip be rewritten or reprogrammed?
Yes, it supports more than 100,000 read/write cycles. However, the first 32 bytes can be permanently locked once written, thanks to its PROM feature—ideal for storing data that should never be changed, such as card IDs or access credentials.

3. Is the SLE4442 compatible with standard smart card readers?
Absolutely. The chip is fully compliant with ISO 7816 standards, making it compatible with most existing contact smart card readers and personalisation equipment used in hotels, fuel stations, and access control systems.

4. What materials can be used for cards built with the SLE4442 chip?
The chip can be embedded in cards made from PVC, PET, PET-G, or PC materials, all following the CR80 standard size (86×54mm). This flexibility allows manufacturers to adapt to different durability or environmental requirements.

5. What are the typical applications of the SLE4442 smart card?
It is widely used in membership cards, hotel key cards, fuel cards, cashless payment cards, and access control systems. Its reliable EEPROM memory and strong protection features make it ideal for environments that require secure, stable, and long-lasting data storage.
