STMicroelectronics STM32F411CEU7

Overview

STM32F411CEU7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 512 KB Flash, 128 KB SRAM, and integrated USB OTG FS controller with on-chip PHY. It delivers 125 DMIPS performance and supports BAM (Batch Acquisition Mode) for low-power sensor hub applications in portable medical devices and industrial edge nodes.

For engineers reviewing the STM32F411CEU7 datasheet, STM32F411CEU7 pinout, STM32F411CEU7 application, or STM32F411CEU7 equivalent, key selection criteria include its 100 MHz real-time execution via ART Accelerator, 12-bit 2.4 MSPS ADC with up to 16 channels, 77 5 V-tolerant I/Os, and dual low-power stop modes (9 µA deep-stop, 42 µA fast-wakeup).

Technical Context

The STM32F411CEU7 implements an Arm Cortex-M4 core with hardware FPU and Memory Protection Unit (MPU), enabling deterministic real-time control and secure task isolation. Its Adaptive Real-Time (ART) Accelerator eliminates flash wait states at 100 MHz, while Batch Acquisition Mode (BAM) allows autonomous peripheral data capture during CPU sleep.

It integrates a full-speed USB OTG FS controller with embedded PHY, SDIO interface for MMC/eMMC, and five SPI/I2S peripherals-two with muxed full-duplex I2S supporting audio-class accuracy via internal PLLI2S. Clock management includes 4–26 MHz HSE, 32 kHz LSE for RTC, and factory-trimmed 16 MHz HSI.

Key Specifications

Pinout & Package

FAQ

Does STM32F411CEU7 support external memory interfaces like SDRAM or NOR Flash?

No. The STM32F411CEU7 lacks FSMC (Flexible Static Memory Controller) or OCTOSPI peripherals. It relies solely on internal 512 KB Flash and 128 KB SRAM. For external memory expansion, consider STM32F429xx or STM32F767xx series, which integrate FSMC and QSPI controllers.

What is the maximum operating temperature rating for STM32F411CEU7 in UFQFPN48 package?

The STM32F411CEU7 in UFQFPN48 package is rated for industrial temperature range: –40°C to +105°C ambient. This is confirmed in Table 3 of DS10314 Rev 8, where "STM32F411xE" variants specify 105°C max junction temperature under defined thermal conditions.

Can the USB OTG FS interface operate in host-only mode without external VBUS sensing?

Yes. The USB OTG FS controller supports host mode with internal VBUS sensing enabled via the USB_OTG_GCCFG register. No external comparator or resistor divider is required for basic host enumeration, though external sensing is recommended for robust overvoltage protection per USB specification.

Is the 96-bit unique ID accessible via standard debug interfaces or only through firmware reads?

The 96-bit unique ID is readable only via firmware using the DBGMCU_IDCODE register and dedicated UID address range (0x1FFF7A10–0x1FFF7A1F). It is not exposed through SWD/JTAG debug access for security reasons - preventing unauthorized extraction during programming or test.
