1 Description

The ST23YL18 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.
Moreover, an ISO 7816-3 EMV-compliant Asynchronous Receiver Transmitter (IART)
communication peripheral is available.

ST23YL18 Description
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 STMicroelectronics Visual Debug
(STVD), provides a set of tools for developing embedded applications. This interface
manages the project configuration, code edition, code generation and program debugging.
A Smartcard ICS emulator (SCICS) and simulator are available for developing and
validating your application code.
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.
