Description
STM32L451CET6 is an ultra-low‑power microcontroller from ST’s STM32L4 family. It uses the ARM Cortex‑M4F core and can run up to about 80 MHz. Designed for battery-powered and energy‑harvesting apps, it offers strong power management with multiple run/stop/standby modes, RAM retention, fast wakeup, and (in some variants) dynamic voltage scaling. Memory and peripherals vary by package; devices in the L451 line typically provide hundreds of KB of flash and tens of KB of SRAM (exact sizes depend on the exact part). Peripherals commonly include GPIO, ADCs (12‑bit), a DAC, timers, USART/UART, SPI, I2C, I2S, and USB FS on many variants, plus cryptographic hardware acceleration and a hardware RNG. It also supports DMA, CRC, and safety features like memory protection. The -CET6 suffix denotes a specific package/pinout and temperature range; consult the datasheet for exact numbers. Development is supported by ST’s CubeMX/HAL/LL tools and the STM32 ecosystem.
