The wide supply range from 1.7V to 3.6V lets you run this MCU directly from a single Li-ion cell (3.0V to 4.2V) or two alkaline cells (1.8V to 3.0V) without an LDO. That saves a regulator and its dropout headroom on a battery-powered board. ## Peripherals and connectivity — USB OTG and more This part includes USB OTG, two I²C, three SPI, up to three UART/USART with IrDA and LIN support, plus SDIO for external storage. Ten 12-bit ADC channels cover analog sensing. The 36 GPIOs are enough for a sensor hub or a motor-control interface with a few encoder inputs. The internal oscillator means you can skip an external crystal for cost-sensitive builds, though you'll want one for precision timing. ## Package and footprint — 48-UFQFPN (7x7 mm) The tape-and-reel suffix (TR) means it ships on 13-inch reels for automated pick-and-place. That means it's safe to design into new production runs without a last-time-buy clock ticking.","metaTitle":"STM32F401CBU6TR MCU, ARM Cortex-M4, 84 MHz, 128 KB Flash","metaDescription":"STM32F401CBU6TR 32-bit ARM Cortex-M4 MCU, 84 MHz, 128 KB Flash, 64K x 8 SRAM, -40°C to 85°C, 48-UFQFPN.

Pin-compatibility across the STM32F401 density options in the same package is standard — the CBU6 (128 KB) and CCU6 (256 KB) share the same footprint and pinout, so a board designed for one can accept the other with a firmware update."},{"question":"How does STM32F401CBU6TR compare to STM32L151CBU6A?","answer":"The STM32F401CBU6TR runs a Cortex-M4 with DSP at 84 MHz, has USB OTG, and more SPI/UART channels. The series targets ultra-low-power battery life; the F4 series targets performance with DSP. For a design that needs 84 MHz throughput and USB OTG, the F401 is the pick; for a coin-cell sensor node, the L151 draws less current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F401CBU6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F401CBU6TR when reusing this data.
