It packs a rich peripheral set including CANbus, QSPI, multiple I²C and SPI interfaces, and a 19-channel 12-bit ADC, all in a 132-UFBGA package. ## 80 MHz Cortex-M4 — timing headroom for control loops The 80 MHz core speed with single-cycle multiply and hardware FPU provides throughput for real-time control loops. The 512 KB Flash is sized for moderate application code plus a bootloader. The STM32L471QEI7 is marked end-of-life (EOL) in the supply chain. ## Connectivity — CAN and QSPI confirmed Yes, this part supports both CANbus and QSPI. The CAN interface handles industrial fieldbus and automotive-style networks; QSPI gives you a fast serial memory bus for external Flash or RAM expansion without tying up the main data bus. The 109 GPIOs leave plenty of headroom for parallel LCDs or sensor arrays.","metaTitle":"ST STM32L471QEI7 ARM Cortex-M4 MCU, 80MHz, 512KB Flash, 132-UFBGA","metaDescription":"STM32L471QEI7 32-bit MCU from STMicroelectronics: ARM Cortex-M4 at 80MHz, 512KB Flash, 128K x 8 RAM, CAN, QSPI, -40 to 105°C.
