The 100-WLCSP package (4.62x4.14 mm) is the smallest footprint in this density tier, making it a fit for space-constrained edge nodes, portable instrumentation, and sensor hubs that need to run on a coin cell or energy harvester. ## Memory and connectivity — sizing the BOM The 320 KB SRAM is enough for double-buffered display frames or large data logs. On the connectivity side, the CAN interface targets industrial bus nodes, USB OTG handles host/device switching for data logging or firmware updates, and QSPI gives a fast interface for external Flash or PSRAM if the on-chip memory runs short.","metaTitle":"STM32L4A6VGY6PTR MCU, ARM Cortex-M4, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4A6VGY6PTR 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 320 KB SRAM, 100-WLCSP.
