Contact chip memory card 256 byte 

The SLE5542 is a smart card IC that builds on the popular SLE4442, offering enhanced compatibility and security. Here are its key technical characteristics:

🧠 Memory & Security

  • EEPROM Memory: 256 bytes (organized as 256 × 8 bits)
  • Protection Memory: 32 × 1-bit for write protection
  • Programmable Security Code (PSC): 3-byte PIN for write access
  • Error Counter: Locks write access after 3 failed PSC attempts

🔐 Data Integrity & Reliability

  • Anti-tearing mechanism: Protects data during power loss
  • Write Endurance: 100,000 cycles
  • Data Retention: Minimum 10 years

📡 Interface & Electrical

  • Contact Interface: ISO/IEC 7816 compliant
  • Communication Protocol: Asynchronous, T=0
  • Operating Voltage: 5V ±10%
  • Clock Frequency: Up to 5 MHz

🌡️ Environmental

  • Operating Temperature: –25 °C to +85 °C

📏 Physical Format

  • Typically embedded in ID-1 format cards (85.6 × 53.98 mm), made of PVC or composite materials

This chip is ideal for access control, loyalty programs, prepaid systems, and secure ID cards, especially where backward compatibility with SLE4442 is needed.

 

  • SLE 5542 replaces SLE 4442
  • SLE 5542 is 100% functional compatible to SLE 4442
  • 256 x 8-bit EEPROM organization of Data Memory
  • 32 x 1-bit Protection Memory
    • Byte-wise write protection of first 32 addresses (byte 0....31) of Data Memory
    • Manufacturer Code for unique identification of application
  • Data Memory (addresses 0....255) alterable only after verification of 3 Byte Programmable Security Code (PSC)
  • Advanced CMOS-technology optimised for security layout
