SLE4428 Smart Card
Code: SLE4428
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. This
IC is one of the most popular in the industry. Download
