双非接触式智能卡微控制器与80 KB的EEPROM ，增强的安全性，加密处理器和优化的RF性能 Dual contactless smartcard MCU with 80 Kbytes EEPROM, enhanced security, cryptoprocessor and optimized RF performance
The is a serial access secure microcontroller custom-designed for secure smartcard applications.
It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. ST23YR80 devices 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/IEC 14443-B standard.
Moreover, an ISO/IEC 7816-3 EMV-compliant asynchronous receiver transmitter IART communication peripheral is available.
