Detailed Description

32-bit ARM Cortex-M4 microcontroller with FPU, up to 84 MHz, 256 KB Flash and 64 KB SRAM. Rich peripherals in a compact footprint. Designed for responsive control, low power, and easy integration across industrial, consumer, and IoT designs.

Key Features

ARM Cortex-M4 core with single-precision FPU, DSP instructions, up to 84 MHz

256 KB embedded Flash, 64 KB SRAM

1.7 V to 3.6 V operating voltage

12-bit ADC (single ADC), high sampling rate, multiple channels

Timers: advanced PWM, general-purpose, watchdogs, SysTick

Communications: SPI/I2S, I2C, USART/UART, USB OTG FS (Full-Speed)

DMA controller, CRC, RTC, unique device ID

Up to 37 GPIOs (depends on package), many 5 V tolerant I/Os

Low-power modes: Sleep, Stop, Standby

Debug and programming: SWD/JTAG, SWO, bootloader from system memory

Industrial temperature support (see package grade)

Key Advantages

Strong compute and math performance with the Cortex-M4 FPU

Small footprint option for space-constrained designs

Low power modes enable battery-friendly products

Mature STM32 ecosystem (STM32Cube HAL/LL, middleware, tools)

Broad community support, libraries, and examples reduce development time

Stable long-term availability and robust ST supply chain

Cost-effective for mainstream control and signal processing tasks

Packaging

Type: Wafer-Level Chip-Scale Package (WLCSP, indicated by “Y”), compact footprint for high-density layouts

Package/Case code: 1057 (internal mapping code; confirm mechanical drawing on datasheet)

Typical ball count and layout: 49-ball grid (WLCSP49), fine pitch; VDD/VSS power pins distributed for low impedance

Material: Silicon die with SnAgCu solder balls; RoHS compliant; MSL Level typically 1

Size: Ultra-compact WLCSP package; small x–y dimensions suitable for wearables and portable devices

Pin configuration: Dense BGA-style array; multiplexed GPIO functions (SPI/I2S, I2C, USART/UART, USB, timers, ADC inputs)

Thermal characteristics: Low thermal mass; junction-to-ambient depends on PCB copper area and vias; use solid ground/power planes for heat spreading

Electrical properties: 1.7–3.6 V supply; many 5 V tolerant I/Os; integrated ESD protection; robust clock options (internal/external); USB FS PHY integrated

Lifecycle

Status: Active, not nearing discontinuation based on current market data

Pin-to-pin or closely compatible alternatives to consider:

- STM32F401CCU6 (UFQFPN48, same memory size, similar pinout in 48-pin leaded package)

- STM32F401CCT6 (LQFP48, same memory size, easier hand-soldering)

- STM32F401CBU6 / CBU6 (UFQFPN48, 128 KB Flash variant)

- STM32F401CEU6 / CET6 (UFQFPN48/LQFP48, 512 KB Flash upgrade)

- STM32F411CCU6 / CCT6 / CEU6 (higher performance up to 100 MHz, more Flash/RAM; check peripheral differences)
