ST23R160：ST23 Dual Interface Secure MCU with 160 KBytes EEPROM, enhanced security and Nescrypt cryptoprocessor, RF Type B (Contectless High end ID-Passport/PKI)

ST23R160 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.

An RF Interface including an RF universal asynchronous receiver transmitter (RFUART) enables contactless communication up to 848 Kbits/s compatible with the ISO 14443-B standard and also enables Innovatron (type B’) communication.

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