SLE4442 / SLE5542 Contact IC Chip Smart Cards
DAFTags SLE4442 and SLE5542 contact IC cards are smart cards with a 256-byte EEPROM for access, identification, membership, and contact-reader data projects. The card must be inserted into a compatible contact reader and uses ISO 7816-3 communication.
SLE4442 and SLE5542 are compatible in function, but SLE5542 is offered with an extended temperature range. The PSC, memory sectors, write protection, and card craft should be confirmed before production.
The Customer Pain Points
- SLE4442 and SLE5542 are similar but not identical in every project: The chips are compatible in function, but the selected version and temperature range should match the reader, card application, and operating environment.
- The card must be inserted into a contact reader: It will not work with an NFC phone or a contactless RFID reader.
- Write protection is irreversible: Each 16-byte sector can be protected against future writing. Once the protection bit is set, the sector cannot be made writable again.
- The PSC setup must be controlled: The programmable security code protects memory access. Confirm who sets, stores, and manages the code before production.
- The memory layout must match the software: The 256-byte EEPROM is divided into 16 sectors of 16 bytes. Sector allocation and data length should be agreed with the reader and software supplier.
What Is an SLE4442 / SLE5542 Contact IC Card?
An SLE4442 or SLE5542 contact IC card is a CR80 smart card with a 256-byte EEPROM and a gold contact pad. The reader makes physical contact with the card to read or write data.
The chip uses a serial three-wire bus and conforms to ISO 7816-3. It supports programmable security and sector-level write protection for contact-card identification and stored-data applications.
Key Features
- SLE4442 / SLE5542 Chip: Compatible contact memory chips with card-reader support.
- 256-Byte EEPROM: Data storage organized into 16 sectors of 16 bytes.
- Sector Write Protection: Each sector can be protected against future writing through the protection memory.
- Programmable Security Code: PSC protection helps prevent unauthorized access to the memory.
- ISO 7816-3 Communication: Serial three-wire bus for compatible contact-card readers.
- Custom Card Printing: Logo, text, image, color, and other card craft options can be discussed.

Reader Compatibility
The card requires a contact reader that supports SLE4442 or SLE5542 and reads ISO 7816-3 contact cards. It cannot be read by an NFC phone.
Send the reader model, software requirements, memory-sector plan, PSC setup, and write-protection requirements before ordering. Test a programmed sample in the actual system before bulk production.

FAQ
What is the difference between SLE4442 and SLE5542?
The chips are compatible in function, but SLE5542 is listed with an extended temperature range of -25 to +85 C. Confirm the required temperature range before selecting the chip.
Will this card work with an NFC phone?
No. This is a contact card and must be inserted into a compatible contact reader. It is not an NFC or contactless card.
Can the memory be protected from writing?
Yes. Each 16-byte sector can be protected with a protection bit. The protection is irreversible, so the data map must be planned before production.
Can you set the PSC code?
The PSC setup can be discussed. Confirm the required code, who will manage it, and whether it should be changed from the default setting.
Can the card be printed and encoded?
Yes. Printing, numbering, barcode, magnetic stripe, signature panel, and encoding can be discussed for the project.
Can I request samples?
Sample availability depends on the current production schedule. Test the card with your reader and software before approving bulk production.
