STM32L452 in STM32 Family
The STM32L452 sub-family from STMicroelectronics is a high-performance ultra-low-power microcontroller series based on the Arm Cortex-M4 32-bit RISC core. Operating at frequencies up to 80 MHz, these devices balance computational power with extreme energy efficiency, utilizing ST's proprietary ART Accelerator and FlexPowerControl technology. They are designed for energy-conscious applications requiring a floating-point unit, comprehensive digital signal processing capabilities, and advanced integrated peripherals like USB 2.0 crystal-less device support.
Variants in This Sub-Family
Variants within the STM32L452 sub-family are primarily distinguished by their package types and memory densities. Flash memory options range from 256 KB to 512 KB. Package configurations vary significantly to meet different PCB density requirements, offering options from the compact UFQFPN48 and WLCSP64 for space-constrained wearables to larger LQFP64 or LQFP100 packages which provide higher I/O counts for complex industrial control interfaces.
