The 48-LQFP package (7x7 mm) with 39 I/O fits space-constrained PCBs where a smaller QFN might be too fine-pitch for manual rework. ## Peripheral set and connectivity The 10x12-bit ADC and 2x12-bit DAC handle analog front-end tasks without an external converter. Brown-out detect, DMA, PWM, and a watchdog are built in, reducing external supervisor IC count. The STM32L431CCT6TR is the Tape & Reel (TR) variant of the base STM32L431CCT6, which ships in trays. Electrically and footprint-identical, the TR suffix is purely a packaging difference for automated pick-and-place assembly. The same part in Cut Tape (CT) is also listed under this order code for smaller-volume builds. ## Lifecycle and production status The active status means no last-time-buy planning is needed for current designs.","metaTitle":"STM32L431CCT6TR STM32L4 ARM Cortex-M4 80MHz MCU, 256KB Flash","metaDescription":"STMicroelectronics STM32L431CCT6TR 32-bit ARM Cortex-M4 MCU, 80MHz, 256KB Flash, 64KB SRAM, 48-LQFP.
