Product details

Overview

STM32F411CEY6UTR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash, 128 KB SRAM, USB OTG FS interface, and 100 MHz max CPU frequency. It integrates a 12-bit 2.4 MSPS ADC, 11 timers (including six 16-bit and two 32-bit), and up to 13 communication interfaces including 3×I²C, 3×USART, 5×SPI/I²S, SDIO, and USB OTG. It targets embedded control in motor drives, medical equipment, and industrial PLCs.

For engineers reviewing the STM32F411CEY6UTR datasheet, STM32F411CEY6UTR pinout, STM32F411CEY6UTR application, or STM32F411CEY6UTR equivalent, key selection considerations include its WLCSP49 package footprint, BAM (Batch Acquisition Mode) for low-power sensor hub operation, ART Accelerator enabling zero-wait-state execution from Flash, and 77 I/Os with 5 V tolerance - critical for mixed-voltage system integration and real-time signal acquisition.

Technical Context

The STM32F411CEY6UTR implements an Arm Cortex-M4 core with hardware FPU and DSP instruction set, supported by the Adaptive Real-Time (ART) Accelerator that eliminates Flash wait states at 100 MHz. Its memory subsystem includes 512 KB of embedded Flash and 128 KB of SRAM, with MPU for secure task isolation.

Power architecture features dynamic efficiency line with three low-power modes: Stop mode (9–65 µA), Standby (1.8–11 µA), and VBAT-powered RTC with subsecond accuracy. Clock system combines 4–26 MHz HSE, 32 kHz LSE for RTC, and factory-trimmed 16 MHz HSI, all feeding dual PLLs - main PLL for CPU and PLLI2S for audio-class I²S timing.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F401CEU6	Same WLCSP49 package, but 256 KB Flash, 64 KB SRAM, no USB OTG PHY, lower 84 MHz max frequency.	Suitable for cost-sensitive, non-USB applications like basic sensor nodes or LED controllers where bandwidth and memory are constrained.	Select when USB host/device capability and >256 KB code space are not required - saves ~15% BOM cost.
STM32F412CEU6	WLCSP49, 512 KB Flash, 256 KB SRAM, USB OTG FS with PHY, adds AES crypto accelerator and Chrom-ART GPU.	Better suited for secure firmware updates and GUI-enabled HMI applications requiring encryption or basic graphics rendering.	Choose when cryptographic operations (AES-128/256) or display acceleration are needed - adds security and UI capability without package change.

Compared with STM32F401CEU6, the STM32F411CEY6UTR provides 2× Flash/SRAM and integrated USB OTG PHY - critical for firmware updates and peripheral hosting. Versus STM32F412CEU6, it lacks crypto acceleration but offers identical core performance at lower unit cost for non-security-critical control tasks.

FAQ

What is the maximum operating temperature range for STM32F411CEY6UTR?

The STM32F411CEY6UTR is rated for industrial temperature range: –40°C to +105°C. This is confirmed in DS10314 Rev 8 Section 3.14 and Table 14 (General Operating Conditions). The extended range supports deployment in harsh environments such as motor drives and outdoor industrial enclosures without derating.

Does STM32F411CEY6UTR support external memory interfaces like SDRAM or Quad-SPI?

No. Unlike higher-end STM32F4xx variants (e.g., STM32F429), the STM32F411CEY6UTR does not integrate FSMC or Octo-SPI peripherals. Its memory subsystem is limited to on-chip 512 KB Flash and 128 KB SRAM. External storage must use SPI, SDIO, or USB mass storage - verified in Section 2.1 (Compatibility) and Table 2 of the datasheet.

Can the STM32F411CEY6UTR achieve USB device enumeration without external components?

Yes. It integrates a full-speed USB 2.0 OTG PHY with internal transceiver and 1.5 kΩ pull-up resistor control on USB_DP. Only standard USB termination (15 kΩ pull-downs on DP/DM) and proper VBUS detection circuitry are required - detailed in Section 3.27 and Figure 132 of DS10314 Rev 8.

Is the WLCSP49 package of STM32F411CEY6UTR compatible with standard reflow profiles?

Yes. The WLCSP49 package (A0ZV variant) complies with JEDEC J-STD-020 moisture sensitivity level 3 and supports standard Pb-free reflow profiles (peak 260°C). Package mechanical data and thermal characteristics are specified in Section 7.2 of DS10314 Rev 8, including recommended stencil design and solder paste volume.
