Product details

What this chip does in the assembly

The STM32L4S9VIT6 is an STMicroelectronics ARM Cortex-M4 MCU — the high-density member of the STM32L4S series, packing 2 MB of Flash and 640 KB of SRAM for firmware-heavy applications like connected industrial sensors, human-machine interfaces, and audio processing nodes.

The 120 MHz core clock lets the Cortex-M4 handle real-time control loops and DSP math without an external coprocessor. The 640 KB RAM gives headroom for multiple buffered sensor streams and a FreeRTOS heap.

Package and temperature grade for the environment

Housed in a 100-LQFP (14x14 mm) with 77 I/O lines, this is a standard surface-mount footprint for two-layer or four-layer boards.

STMicroelectronics lists the STM32L4S9VIT6 as active (current production). No last-time-buy or end-of-life notice has been issued.

Frequently asked questions

What is the maximum clock speed of STM32L4S9VIT6?

The maximum clock speed is 120 MHz, driven by the internal oscillator or an external clock source.

Does STM32L4S9VIT6 have a replacement or equivalent?

No official replacement or direct second-source equivalent is listed by STMicroelectronics. The part remains active, so no substitute is required for new designs. For dual-sourcing, consider a pin-compatible STM32L4S9VI variant (same package and memory) if available.
