STM32L4P5VET6

STM32L4P5VET6 is STMicroelectronics’ STM32L4 ultra-low-power microcontroller, part of the L4 family. It uses a 32‑bit ARM Cortex-M4F core (DSP/FPU) for energy-efficient performance. It runs up to ~80 MHz and supports multiple low‑power modes (Run, Sleep, Stop, Standby) with RAM retention in some modes. Exact Flash/SRAM and peripherals vary by device; the L4P5VET6 SKU in the VET6 package targets mid-range applications. Peripherals typically include ADCs, various timers, and serial interfaces (USART/SPI/I2C); USB and cryptography/RNG blocks are available on many L4 SKUs. ST provides development tools (STM32CubeMX, HAL/LL drivers) and supports GCC, Keil, IAR with ST‑Link or other SWD debuggers. Common uses: wearables, sensors, IoT nodes, portable medical devices. For precise memory sizes and peripheral sets, consult the specific datasheet for STM32L4P5VET6.
