The 128 KB of Flash and 40 KB of SRAM are sized for moderate firmware stacks — think a Bluetooth LE gateway, a field sensor node, or a portable instrument — not a full GUI or dual-image OTA partition. ## Connectivity and peripherals — Quad SPI, USB, multiple UARTs On the peripheral side you get Quad SPI for external Flash or RAM expansion, USB 2.0 full-speed, multiple I2C and SPI buses, plus UART/USART and LINbus for industrial fieldbus. The 10-channel 12-bit ADC covers analog inputs like thermistors or current shunts. The 26 GPIOs in the 32-UFQFPN package are tight — plan your pin allocation early if you need both a display interface and a sensor array. ## Package and footprint — 5x5 mm, exposed pad, MSL3 Housed in a 32-UFQFPN (5x5 mm) with an exposed pad, this is a compact surface-mount package suited for space-constrained PCBs.","metaTitle":"STM32L412KBU6 STM32L4 MCU, ARM Cortex-M4, 80 MHz","metaDescription":"STM32L412KBU6 32-bit MCU, 80 MHz Cortex-M4, 128 KB Flash, 40 KB SRAM, 1.71-3.6 V, -40 to 85°C, 32-UFQFPN.
