How to program the STM8TL5xxx

Flash program memory and data EEPROM

Introduction

This manual describes how to program Flash program memory and data EEPROM on

STM8TL5xxx microcontrollers. It applies to STM8TL5xxx devices. It is intended to provide

information to the programming tool manufacturers and to the customers who want to

implement programming by themselves on their production line.

The in-circuit programming (ICP) method is used to update the content of Flash program

memory and data EEPROM while the user software is not running. It uses the Single wire

interface module (SWIM) to communicate between the programming tool and the device.

In contrast to the ICP method, in-application programming (IAP) can use any

CAN...). IAP has been implemented for users who want their application software to update

itself by re-programming the Flash program memory during program execution. The main

advantage of IAP is its ability to re-program Flash program memory and data EEPROM

when the chip has already been soldered on the application board and while the user

software is running. Nevertheless, part of the Flash program memory has to be previously

programmed using ICP.

For details on memory implementation and features, registers or stack top addresses, refer

to the product datasheet.
