The CLXSA128KA4 Smart Card incorporates a 262,144 Bit Serial Electrically Erasable PROM in a 32,768 by 8 architecture. This card is for advanced, low power applications such as large record storage and medical applications where low cost per bit is a driving factor.

The CLXSA128KA4 offers a straight memory array that features ultra-high-endurance EEPROM for data that changes frequently. The whole array, of 256K bits, is guaranteed at 100,000 ERASE/WRITE (E/W) cycles.

The CLXSA128KA4 advanced CMOS technology makes this device ideal for low-power non-volatile data storage applications.

The CLXSA128KA4 is available in the standard ISO 7816, CR80 package or SIM block size.
