Smartcard ICs
ST23, core solutions

The first products in the new family – the ST23YS02 and ST23YS08 – integrate 2 and 8 Kbytes of EEPROM respectively with the most recent improvements in security technology. They are intended for banking, loyalty cards and other financial applications. The advanced ST23 family joins the established ST19 series in a complete portfolio of secure devices.
Competitive pricing, aided by their 0.13-micron manufacturing process, makes them ideal for a range of finance applications, but particularly for EMV migration from magnetic stripe to SDA (static data authentication) chip and PIN cards. A simplified architecture makes them easy to use to further reduce costs for code developers.
Both MCUs embed an eDES (enhanced DES) accelerator and support AES (Advanced Encryption Services) cryptography, and are certified to meet current EMVCo requirements. They provide ISO and IART interfaces, with planned additions to the family including crypto processors and contactless products.
Incorporating the security improvements developed over the last two years, the first small-memory devices in the family offer highly cost-effective solutions for SDA migration and loyalty cards.
