That Flash density is enough to hold a full wireless protocol stack (LoRa, Zigbee, or BLE) plus application code without external memory, while the SRAM supports large data buffers or an RTOS with multiple task stacks. The part integrates a rich set of peripherals including USB OTG, CANbus, multiple I²C and SPI interfaces, and a 12-bit ADC with 16 channels — making it a natural fit for battery-powered industrial sensors, portable medical instruments, or IoT edge nodes that need to log data and talk to a host or a vehicle bus. ## Supply range and temperature grade The MCU operates from 1.71 V to 3.6 V, covering single-cell Li-ion and two-cell alkaline supplies directly. The -40 to 85 °C industrial temperature range qualifies it for outdoor telecom cabinets and factory-floor controllers.","metaTitle":"ST STM32L4Q5CGU6P ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STM32L4Q5CGU6P 32-bit MCU with ARM Cortex-M4 at 120 MHz, 1 MB Flash, 320 KB SRAM, USB OTG, CAN, -40 to 85 °C.
