ST23 Contact Secure MCU with 4 Kbytes EEPROM, enhanced security

SB23ZE04 devices are secure microcontrollers specially designed for secure smartcard applications.

They are based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes of linear addressing space. SB23ZE04 devices are manufactured using an advanced highly reliable ST CMOS EEPROM technology.

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