Product details

80 MHz Cortex-M4 with FPU — compute headroom for DSP and control

The STM32L462CEU6 is a 32-bit single-core MCU built around the ARM Cortex-M4 core with a floating-point unit, clocked at 80 MHz.

Industrial temperature grade and peripheral set — where it fits

The on-chip 12-bit ADC (10 channels) and single 12-bit DAC cover analog sensing and control-loop output without an external converter. Brown-out detect, DMA, and a watchdog timer are included, reducing the need for supervisory ICs.

The base product number STM32L462 covers multiple package and memory variants within the STM32L4 series.

Frequently asked questions

Is STM32L462CEU6 obsolete or end-of-life?

No — the lifecycle status is Active (current production).

What is the core of STM32L462CEU6?

It uses an ARM Cortex-M4 core with a 32-bit single-core architecture, clocked at 80 MHz. The Cortex-M4 includes a single-cycle hardware multiply and a floating-point unit.

Is STM32L462CEU6 compatible with the STM32L4 series?

Yes — it is part of the STM32L4 series and shares the same peripheral library, low-power architecture, and pin compatibility across many L4 family members in the same package footprint. For example, STM32L452 devices in the same 48-UFQFPN package are pin-compatible, though memory and feature sets differ.

How does STM32L462CEU6 compare to STM32L151CBU6A?

The L4 part is a step up in compute and memory for designs that need more throughput or larger firmware images.
