The supply range is 1.71 V to 3.6 V, and the temperature grade is -40°C to 85°C. The 80 MHz core speed handles real-time control loops, sensor fusion, and protocol stacks. The single-cycle multiply and hardware FPU handle fixed- and floating-point math efficiently. ## Memory sizing and peripheral set 1 MB Flash gives room for a full application stack plus a small file system or bootloader; 128 KB RAM supports moderate frame buffers and multi-packet USB transfers. The 51 GPIOs in the 64-LQFP package leave enough pins for a parallel LCD interface, external memory via QSPI, and a handful of sensors or actuators. On-chip brown-out detect and a watchdog reduce external supervisor IC count.","metaTitle":"ST STM32L476RGT6U ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L476RGT6U 32-bit ARM Cortex-M4 MCU, 80 MHz speed, 1 MB Flash, 128 KB RAM, 64-LQFP, -40°C to 85°C.
