The 80 MHz Cortex-M4 core with FPU handles single-cycle DSP and floating-point math, which matters for sensor fusion or motor-control loops that would otherwise burden a Cortex-M0+ or M3. The 1 MB Flash gives headroom for a full RTOS stack plus application code, reducing the need for external serial Flash in many designs. The 128 KB SRAM is enough for moderate data buffers and stack; if your application runs heavy graphics or large audio buffers, you may need to budget for external PSRAM or SDRAM. The peripheral set includes CAN, USB OTG, multiple SPI/I²C/UART, QSPI, and an LCD controller, which covers most industrial and IoT connectivity needs without external transceivers or bridge chips. The 12-bit ADC with 16 channels and dual 12-bit DAC handle analog front-end tasks on-chip.","metaTitle":"ST STM32L476JGY3TR ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L476JGY3TR 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 1 MB Flash, 128 KB RAM, -40 to 125 °C, 72-WLCSP.
