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 \u00d7 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.<\/p>\n

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.<\/p>\n

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\u00d754 mm) and can be made of PVC, PET, PET-G, or PC materials, flexibly meeting various environmental and durability requirements.<\/p>","protected":false},"excerpt":{"rendered":"
