Connectivity spans I²C, SPI, Quad SPI, UART/USART, LIN, IrDA, infrared, and USB — enough to talk to external Flash, sensors, displays, and a host controller without glue logic.","metaTitle":"STM32L412RBT6 STM32L4 MCU, ARM Cortex-M4, 80 MHz","metaDescription":"STM32L412RBT6 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 80 MHz core, 128 KB Flash, 40 KB RAM, 52 I/O, -40°C to 85°C.

The Cortex-M4 in the STM32L412RBT6 adds DSP and FPU capability that the M3-based part lacks, so the choice depends on whether you need the math acceleration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L412RBT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L412RBT6 when reusing this data.
