DescriptionDEVELOPING A USB SMARTCARD READER WITH ST7SCR
Datasheet Summary with AI

This document is an application note from STMicroelectronics that describes the firmware implementation for a USB Smart Card Reader using the ST7SCR microcontroller.
The firmware is divided into four parts: USB management, Chip Card Interface Device (CCID) implementation, Interface Device (IFD) implementation, and 7816 UART Smartcard Interface (CRD) management.
The main loop of the firmware polls USB transactions using a state machine process.
The CCID implementation conforms to the Universal Serial Bus Device Class Specification for USB Chip/Smart Card Interface Devices and contains functions for managing Bulk-in/Bulk-out messages.
The IFD implementation contains functions for managing ISO 7816 protocol types and levels, while the CRD library provides low-level functions for directly accessing the hardware and communicating with the Integrated Circuit Card (ICC).
The document also provides detailed descriptions of the functions and their usage within the firmware.
