ST23YT34：ST23 Secure MCU with USB, enhanced security and 34 KBytes EEPROM

The ST23YT34 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.

The ST23YT34 is a secure USB microcontroller based on the ST23 core architecture. Its high security level and versatile communication interfaces address user identification functions for computer or network access or for computer-based local or remote applications.

The ST23YT34 features a USB full-speed interface for communication with computers as well as various I/Os.

Moreover, an ISO 7816-3 EMV-compliant Asynchronous Receiver Transmitter (IART) communication peripheral is available.

In order to meet environmental requirements, ST (also) offers these devices in ECOPACK^®packages. ECOPACK^®packages are lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com..
