ST23ZL48

ST23 Contact Secure MCU with 48 Kbytes EEPROM, enhanced security and Nescrypt cryptoprocessor (Contact/PKI)

Quick View Resources

The ST23ZL48 is a serial access microcontroller custom-designed for secure smartcard applications.

It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes of linear addressing space. ST23ZL48 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.
