ACS offers a variety of memory cards that may be used with a range of smart card readers/writers.
These are the SLE5542 and the SLE5528 memory cards.

SLE5542 Memory Card Features:    

  • SLE5542 is 100% functional compatible to SLE4442    
  • Intelligent 256-Bytes EEPROM    
  • Write-protect function    
  • Programmable Security Code (PSC)    
  • EEPROM is organized 256 x 8 bit offering the possibility of programmable write protection for each byte    
  • Data Memory alterable only after verification of 3-Byte Programmable Security Code (PSC)    


SLE5528 Memory Card Features:    

  • SLE5528 is 100% functional compatible to SLE4428    
  • 1KB EEPROM    
  • Write-protect function    
  • Programmable Security Code verification logic    
  • All the memory, except for the PSC, can always be read    
  • The memory can be written or erased only after PSC verification    
  • After eight successive incorrect entries the error counter will block any subsequent attempt at PSC verification and hence any possibility to write and erase
