The ARM Cortex-M4 core includes a single-precision floating-point unit (FPU) that accelerates sensor fusion and control-loop math without a separate DSP. At 80 MHz, the core delivers approximately 100 DMIPS, enough for real-time audio processing, motor control, and protocol stacks. The 128 KB SRAM provides headroom for double-buffered ADC data, USB packet buffers, and a modest RTOS heap. If you plan to run a GUI stack or large audio buffers, budget for external PSRAM via the QSPI interface. ## Supply range and power management A single Li-ion cell (3.0 V to 4.2 V) or two alkaline cells (1.8 V to 3.0 V) can power the MCU directly without a regulator. The STM32L4 series is known for sub-100 nA shutdown currents and multiple low-power run/sleep modes; the exact current figures depend on the clock configuration and peripheral gating, but the architecture is built for energy-harvesting and long-life sensor nodes.","metaTitle":"STMicroelectronics STM32L476RCT6 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STM32L476RCT6 32-bit MCU: ARM Cortex-M4 at 80 MHz, 256 KB Flash, 128 KB SRAM, 1.71-3.6 V supply, 51 I/O, 64-LQFP.
