Description ST23R160
1 Description
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.
