They are based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes of linear addressing space. ST23ZR04 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.

The range of tools includes solutions to help you to develop and debug your application and evaluate smartcard products and their peripherals. An Integrated Development Environment (IDE), the ST Visual Develop (STVD), provides a set of tools for developing embedded applications. This interface manages the project configuration, code edition, code generation and program debugging. All the information needed to generate the application code and personalization will be collected in a delivery file (.DLV extension). This file is created using the Delivery menu of the STMicroelectronics configuration software tool, SCOOL. 2 Revision history Table 1.
