The 80 MHz clock rate sets the throughput ceiling for real-time control loops and signal processing — a sensor fusion algorithm or motor-control FOC loop runs without a separate DSP. The 64 KB on-chip Flash and 40 KB SRAM leave headroom for a typical sensor-node firmware stack (RTOS, HAL, application code) without external memory. The 40 KB SRAM is enough to buffer several seconds of audio or a full frame of image data from a low-resolution camera. ## Supply range and connectivity for battery-powered nodes The internal oscillator and brown-out detect keep the system stable across the full range. Connectivity includes I²C, SPI, Quad SPI, USART/UART, and USB — enough to interface with external sensors, displays, wireless modules, or a host PC. The 10-channel 12-bit ADC samples analog inputs (temperature, pressure, battery voltage) without an external converter. The internal DMA can move ADC results directly to SRAM, keeping the CPU free for control tasks. ## 48-LQFP — board-fit and rework The internal oscillator and brown-out reset are rated across this range.","metaTitle":"STM32L412C8T6 STM32L4 MCU, 80 MHz Cortex-M4, 64 KB Flash","metaDescription":"STMicroelectronics STM32L412C8T6 ARM Cortex-M4 MCU, 80 MHz, 64 KB Flash, 40 KB SRAM, 48-LQFP.
