ST23YL80：ST23 Contact Secure MCU with 80 Kbytes EEPROM, enhanced security and Nescrypt cryptoprocessor (Contact ID/PKI)

The ST23YL80 is a serial access secure microcontroller custom-designed for secure smartcard applications.

It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. ST23YL80 devices are manufactured using an advanced highly reliable ST CMOS EEPROM technology.

Moreover, an ISO/IEC 7816-3 EMV-compliant asynchronous receiver transmitter (IART) communication peripheral is available.
