That core includes a single-precision FPU and DSP instructions, so you can run sensor fusion, FFT, or PID loops without an external DSP — unusual for a part targeting sub-1 mA active draw. That 1.71 V floor is the real differentiator — many Cortex-M4 parts need 2.0 V minimum, which forces a boost stage in single-cell designs. ## Peripheral mix — what the 114 I/O actually connects The QSPI interface runs at up to 80 MHz, useful for memory-mapped external Flash. An LCD controller is baked in, so you can drive a segment LCD directly without an external driver chip — a cost saver in metering or HMI panels. The brown-out detect and watchdog peripherals are on-die, reducing external supervisor IC count. ## Temperature grade and package — industrial, not automotive It does not meet AEC-Q100 requirements, so avoid it for under-hood or cabin electronics. The 144-LQFP (20x20 mm) is a standard footprint with 0.5 mm pitch — the same as many STM32F4 and STM32L4 siblings, easing a pin-compatible swap if you need more Flash or a different peripheral set. ## Lifecycle and sourcing posture ST lists the STM32L476ZET6 as Active (current product). For new designs, there is no urgency to qualify a second source.","metaTitle":"STM32L476ZET6 ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32L476ZET6 32-bit MCU, ARM Cortex-M4 at 80 MHz, 512 KB Flash, 128 KB SRAM, 114 I/O, -40°C to 85°C, 144-LQFP.
