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.

ST23R160 Revision history
1.1 Development environment
Development tools for smartcard products include a complete range of hardware systems
and software tools from STMicroelectronics and third-party tool suppliers. 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.
