1 Description
The ST21Y036 product is a serial access microcontroller specially designed for cost-
effective secure mobile 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 EEPR OM technology.
The device includes a DES accelerator.
A serial interface fully compatible with the ISO 7816-3 standard (T = 0 and T = 1) for
Smartcard applications is available.
A CRC calculation block is also available and is directly accessible by the User.
The product architecture is optimized for low power consumption applications. A flexible
clock generator module prov ides increased performance for specific current requirements.

1.1 Development environment
Development tools for smartcard products include a complete range of hardware systems
and softw are tools from STMicroelectronics and third- party tool suppliers. The r ange 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 STMicroelect ronics Visual Deb ug
(STVD), provides a set of tools for developing embedded applications. This interface
manages the project configuration, code editi on, code generation and program debugging.
An emulator (SCICS) and a 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.
