Core runs at 80 MHz, with 64 KB Flash and 40K x 8 RAM. ## I/O and connectivity 52 I/O lines in a 64-UFBGA package — that's a 5x5 mm ball-grid array. The BGA footprint saves board area but needs a solder-paste stencil and X-ray inspection; it's not a hand-solder part. Connectivity includes I²C, SPI, Quad SPI, UART/USART, USB, and IrDA — enough for a sensor hub, a USB bridge, or a data-logger interface. The Quad SPI lets you map an external serial Flash into the memory space without bit-banging. ## What the peripherals tell you The peripheral set includes brown-out detect, DMA, PWM, and a watchdog — so it can run unattended in a remote sensor node and reset itself on a glitch. The internal oscillator means you can skip the external crystal for non-critical timing, saving two pins and a couple of cents. The 16-channel 12-bit ADC is enough for reading multiple analog sensors or monitoring a battery voltage rail.","metaTitle":"ST STM32L412R8I6 ARM Cortex-M4 MCU, 80MHz, 64KB Flash, 64-UFBGA","metaDescription":"STMicroelectronics STM32L412R8I6 32-bit MCU with 80MHz ARM Cortex-M4 core, 64KB Flash, 40K x 8 RAM, 52 I/O, 64-UFBGA package.
