This document describes a firmware and hardware smartcard interface solution based on the STM8 UART1 peripheral.
This document details a complete solution for interfacing with smartcards using the STM8S microcontroller's UART1 peripheral in smartcard mode. It covers the necessary firmware library functions and hardware configuration required to support asynchronous protocol smartcards defined in the ISO 7816-3 standard.
The guide provides an overview of the ISO 7816 protocol, including pin locations and signal transmission details. It also includes specific instructions for connecting a smartcard reader (such as the ST8024 device) to the STM8S microcontroller via GPIO pins and explains how to manage card power-up, reset, data transfer, and security commands.
| Supported Standard | ISO 7816-3 (Class A) |
|---|---|
| Data Bits | Eight data bits plus parity |
| Stop Bits | 0.5 or 1.5 stop bits |
The solution is based on the STM8 UART1 peripheral.
It covers the ISO 7816-3/4 specification for smartcards.
The ST8024 device is used as a complete low-cost analog interface.
