The ST23YS02 is a smartcard MCU with enhanced security and 2 Kbytes high-density EEPROM. Major applications include banking, targeting the EMVCo certificate.
The ST23YS02 is a serial access microcontroller specifically designed for secure smartcard applications, such as banking targeting the EMVCo certificate. It is built on an enhanced STMicroelectronics 8/16-bit CPU core with 16 Mbytes of linear addressable memory and is manufactured using highly reliable CMOS EEPROM technology.
The device includes significant security features, including an active shield, environmental parameter monitoring, and a Hardware Security Enhanced DES accelerator. It also features an AIS-31 class P2 compliant True Random Number Generator (TRNG) and a unique serial number on each die. The chip supports a CPU clock frequency up to 29 MHz and operates with 3V and 5V supply voltage ranges.
