STM8L family compatibility

Doc ID 16993 Rev 3

7/63

All STM8L family microcontrollers use the same application development tools:

●

Embedded single wire interface module (SWIM)

●

Software integrated development environment (IDE) tools including assembler,

simulator, debugger, programmer:

–

ST Visual Develop (ST)

–

Ride (Raisonance)

–IAR

●

In-circuit debugging and programming tools

–

STIce from ST (full hardware emulator)

–

ST-Link from ST

–

RLink from Raisonance (low cost debug/programming tool)

●

Starter kits and evaluation boards

●

C compiler and assembler tool chains (Cosmic, Raisonance, IAR)

●

Firmware libraries (peripheral control examples, MISRA or class B compliance, touch

sensing)

●

Application notes

By using a common development environment, you significantly reduce code maintenance

effort and shorten the time-to-market, especially in cases when an application has to be

migrated from one STM8 microcontroller to another.

By using the drivers provided in the STM8L firmware library to interface with the hardware, it

becomes reasonably straightforward to move the application firmware from one STM8L

product to another. The principle job is analyzing the details on the hardware side, taking

care of the placement and availability of the peripheral I/O functions in the pinout. More

details can be obtained in the STM8L datasheet and further in this document in Section 3.1:

Package pinout.

Figure 1: STM8L family block diagram gives an overview of the STM8L blocks and their

compatibility level, as discussed in the next sections.
