STM32 Microcontrollers

Key Features

• ARM Cortex-M0, M3, M4, M7 and dual-core H7 options
• Flash from 16 KB to 2 MB, SRAM up to 1 MB
• Clock speeds from 32 MHz to 480 MHz
• Rich peripherals: ADC, CAN, USB, Ethernet, timers
• Low-power L-series and mixed-signal G-series
• LQFP, BGA and UFQFPN packages

Packages, Temperature & Applications

STM32 devices are supplied in LQFP, TFBGA and UFQFPN packages from 20 to 240 pins, across commercial and industrial temperature ranges. Applications span industrial automation, motor control, IoT, consumer electronics and embedded Linux-class processing on the H7.

Selection Notes

Pick the core and clock speed for your workload, then match flash and SRAM to your firmware. Confirm the peripherals you need (ADC, CAN, USB, Ethernet) and the package. The L-series adds ultra-low power, while the G-series adds analog-rich digital power control.

Popular Part Numbers

• STM32F103C8T6 — 72 MHz Cortex-M3, the classic entry point.
• STM32F405RGT6 — 168 MHz Cortex-M4F with FPU.
• STM32F407VET6 — adds Ethernet and camera interface.
• STM32F767ZIT6 — 216 MHz Cortex-M7F.
• STM32H743VIT6 — 480 MHz Cortex-M7F with 1 MB SRAM.

Design Considerations

Pick the core and clock speed for the workload, then match flash and SRAM to your firmware and confirm the peripherals you need. The L-series adds ultra-low power for battery operation, the G-series adds fast ADCs and math accelerators for digital power, and the H7 delivers the highest single-core performance.

Why Choose This Series

STM32’s consistent peripheral set, huge ecosystem and long-term availability make it a low-risk choice across the whole performance range, from tiny Cortex-M0 parts to high-end Cortex-M7 devices. Pin- and code-compatible families simplify migration, and the mature HAL and toolchain support reduce development time on industrial, IoT and motor-control projects.
