The CLXSA001KA1 Smart Card incorporates a 1024 bit Serial Electrically Erasable I 2 C PROM in a 128 by 8 architecture. This card is for advanced, low power applications such as small record storage and loyalty applications where low cost is a driving factor. The CLXSA001KA1 offers a straight memory array that features ultra-high-endurance EEPROM for data that changes frequently. The entire array is rated at 1,000,000 ERASE/WRITE (E/W) cycles guaranteed.

The CLXSA001KA1 advanced CMOS technology makes this device ideal for low-power non-volatile code and data applications.

The CLXSA001KA1 is available in the ISO 7816 standard, and CR80 package.
