Hello STMicroelectronics Community,We are evaluating the following STM32 microcontrollers for long-term use in our drone flight controller development: STM32G431 STM32G431KBU6 STM32G474VET6 STM32H743VIT6 STM32H723VGT6 We would like to understand the long-term market availability and product lifecycle commitment for these MCUs.Could you please clarify the following points? Product Longevity: For how many years will these MCUs remain available for purchase and production? Lifecycle Status: Are these models active, recommended for new designs, or approaching end-of-life (EOL)? Long-Term Supply: Does STMicroelectronics provide a guaranteed supply period or product longevity commitment for these specific MCUs? EOL Notification: If any model is planned for discontinuation, how much advance notice will be provided? Replacement & Migration: If a model becomes obsolete, will a pin-compatible or functionally compatible replacement be available? Our concern is to avoid selecting an MCU that may become unavailable after a few years, forcing us to redesign the flight controller or PCB.We would appreciate your guidance on the expected product lifecycle and long-term supply assurance for each model.

Hello STMicroelectronics Community,

We are evaluating the following STM32 microcontrollers for long-term use in our drone flight controller development:

STM32G431
STM32G431KBU6
STM32G474VET6
STM32H743VIT6
STM32H723VGT6

We would like to understand the long-term market availability and product lifecycle commitment for these MCUs.

Could you please clarify the following points?

Product Longevity: For how many years will these MCUs remain available for purchase and production?
Lifecycle Status: Are these models active, recommended for new designs, or approaching end-of-life (EOL)?
Long-Term Supply: Does STMicroelectronics provide a guaranteed supply period or product longevity commitment for these specific MCUs?
EOL Notification: If any model is planned for discontinuation, how much advance notice will be provided?
Replacement & Migration: If a model becomes obsolete, will a pin-compatible or functionally compatible replacement be available?

Our concern is to avoid selecting an MCU that may become unavailable after a few years, forcing us to redesign the flight controller or PCB.

We would appreciate your guidance on the expected product lifecycle and long-term supply assurance for each model.

You can find the longevity commitment on the Product Page; eg,

Hover your mouse over the icon for more details:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
