Description ST23ZC08

1 Description

ST23ZC08 products are secure microcontrollers specially designed for secure smartcard applications.
They are based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes of linear addressing space. ST23ZC08 devices are 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 Kbps compatible with the ISO/IEC 14443-A and ISO/IEC 14443-B standard.
