The industrial temperature range from -40°C to 105°C means this MCU can live in an outdoor telecom cabinet or a motor-drive enclosure without derating worries. ## 80 MHz Cortex-M4 — what the clock buys you The 80 MHz core runs a real-time control loop with floating-point math or a basic DSP filter chain. This MCU carries a rich peripheral set: CANbus, USB OTG, multiple SPI/I²C/UART interfaces, plus a Quad-SPI for external Flash and an LCD driver for segment displays. The 16-channel 12-bit ADC and dual 12-bit DAC cover analog front-end needs without an external converter. Brown-out detect and a watchdog timer are built in — useful for fail-safe designs in industrial or automotive-adjacent environments.","metaTitle":"ST STM32L476JGY7TR ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L476JGY7TR 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 128 KB RAM, -40 to 105°C, 72-WLCSP.
