STM32L451CET6

The STM32L451CET6 is a low‑power 32‑bit microcontroller from ST’s STM32L4 family, built around an ARM Cortex‑M4 core with a floating‑point unit and DSP instructions. It targets energy‑efficient embedded applications that need moderate performance.
Key points:
- Core and performance: Cortex‑M4, up to about 80 MHz, with FPU/DSP for signal processing.
- Power efficiency: multiple low‑power modes (sleep/stop/standby) and power/performance scaling for long battery life.
- Memory and package: on‑chip flash (typical mid‑range sizes) and RAM; ET6 suffix denotes the package variant and configuration (check datasheet for exact figures).
- Peripherals: rich mix of timers, ADCs/DACs, comparators, op‑amps, and standard interfaces (USART/UART, SPI, I2C, USB FS; CAN available on some parts).
- Development: supported by STM32CubeMX and HAL/LL drivers; broad ecosystem with evaluation boards and example projects.
Use cases include wearables, sensors, IoT nodes, portable medical devices, and other battery‑powered embedded systems where low power and reliable peripherals are needed. For exact specs, consult the STM32L451CET6 datasheet/reference manual.
