ST23YR48 Dual Contactless Smartcard MCU with 48 K of EEPROM

The ST23YR48 product is a serial access microcontroller specially designed for secure smartcard applications.

It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.

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

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