ST23L160:ST23 Contact Secure MCU with 160 Kbytes EEPROM, enhanced security and Nescrypt cryptoprocessor

ST23L160 devices are serial access microcontrollers custom-designed for secure smartcard applications.

They are based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. They 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.
