SB23ZD18：ST23 Contact Secure MCU with 18 Kbytes EEPROM, enhanced security

SB23ZD18 products 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. SB23ZD18 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. Moreover, a slave I2C interface, supporting Fast-mode (400 kb/s) is also available.
