SLE4428 Secure Memory Smart Cards



SLE4428 is one of the most common chip that used in security area. SLE4428 has a PSC verification logic. All the memory, except for the PSC, can always be read. The memory can be written or erased only after PSC verification. The error counter can always be written. After eight successive incorrect entries the error counter will block any subsequent attempt at PSC verification and hence any possibility to write and erase.
> 1024 * 8 bit EEPROM organization
> Byte-wise addressing
> Irreversible byte-wise write protection
> 1024 * 1 bit protection memory organization
> Serial three-wire bus
> End of programming indicated on data output
> Data retention for minimum of ten years
> Contact configuration and serial interface in accordance to
> ISO standard 7816 (synchronous transmission)
> Data can only be changed after entry of the correct
> 2-byte programmable security code (PSC)

     SLE4428 Chip upgrade product is SLE5528, the function and feature of both chip is exactly same.

The chip completely compatible with SLE4428 is FM4428. The performance of FM4428 is the same as SLE4428 chip. As the price of SLE4428 is relatively higher, so the FM4428 is used in many projects instead of SLE4428 chip.

        A smart card is a small plastic card containing a computer chip. People use smart cards along with personal identification numbers (PINs) to log on to a network, a computer, or a device. Using a smart card is more secure than using a password because it's more difficult for someone to steal a smart card and learn your PIN than to learn your password. Smart cards are generally issued by information technology (IT) departments in large organizations. To use a smart card, you also need a smart card reader - a device that's installed in or connected to your computer and that can read the information stored on a smart card.
