Product details
Overview
STM32F411CEU6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max clock, 512 KB Flash, 128 KB SRAM, and USB OTG FS interface - deployed in motor control, medical sensors, and industrial PLCs where real-time processing and low-power operation are critical.
For engineers reviewing the STM32F411CEU6TR datasheet, STM32F411CEU6TR pinout, STM32F411CEU6TR application, or STM32F411CEU6TR equivalent, key selection factors include ART Accelerator-enabled zero-wait-state flash execution, BAM (Batch Acquisition Mode) for sensor hub duty cycling, 12-bit 2.4 MSPS ADC with up to 16 channels, and 77 5 V-tolerant I/Os in UFQFPN48 package.
Technical Context
The device integrates an adaptive real-time memory accelerator (ART Accelerator) that enables deterministic 0-wait-state execution from Flash at 100 MHz, eliminating cache misses in time-critical control loops. Its Batch Acquisition Mode (BAM) allows autonomous peripheral data capture while CPU remains in Stop mode, reducing system-level power by up to 90% during sensor polling intervals.
It features a multi-AHB bus matrix supporting concurrent access to Flash, SRAM, and peripherals, plus a 16-stream DMA controller with FIFOs and burst support - essential for high-throughput audio streaming via I2S or SDIO-based eMMC boot. The embedded 32 kHz RTC oscillator includes hardware calendar and subsecond accuracy, independent of main supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 with FPU, 125 DMIPS @ 100 MHz - enables floating-point math for motor FOC or digital filter implementation without external coprocessor. |
| Memory | 512 KB Flash + 128 KB SRAM - sufficient for dual-bank firmware updates and real-time buffer staging in industrial comms stacks. |
| ADC | 12-bit, 2.4 MSPS, up to 16 channels - supports simultaneous sampling of current/voltage/temperature in 3-phase inverter monitoring. |
| USB | USB 2.0 Full-Speed OTG with on-chip PHY - eliminates external transceiver for host/device switching in portable diagnostic tools. |
| Power | Run: 100 µA/MHz; Stop (Deep Power Down): 9 µA typical - enables battery-backed operation >1 year in wireless sensor nodes. |
| I/O | 77 5 V-tolerant GPIOs, up to 100 MHz toggle - interfaces directly with legacy 5 V logic or industrial level-shifted fieldbus signals. |
| Clocks | 4–26 MHz HSE crystal + 32 kHz LSE RTC oscillator with calibration - ensures precise timekeeping across temperature (-40°C to +105°C). |
Pinout & Package
STM32F411CEU6TR is housed in a 48-pin Ultra-Fine Pitch Quad Flat No-lead (UFQFPN48) package measuring 7 mm × 7 mm with 0.5 mm pitch and exposed thermal pad. Pin definitions conform to ST's standardized STM32F411xE pinout layout (Document DS10314 Rev 8, Section 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power supply and ground rails | Dual-domain supply: VDDA powers analog peripherals (ADC, RTC, reset circuitry); separate VSSA reduces noise coupling into precision conversions. |
| PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD15, PE0–PE15 | General-purpose I/O banks | 77 pins support 5 V tolerance; configurable as EXTI sources, timer channels, or alternate functions including SPI/I2C/USART. |
| PA11/PA12 | USB DP/DM | Dedicated full-speed USB 2.0 differential pair with integrated transceiver - no external PHY required for device/host/OTG operation. |
| PF0–PF1 | OSC_IN/OSC_OUT | Connects to 4–26 MHz external crystal for main system clock; internal trimming enables ±1% frequency stability over temperature. |
| PC13–PC15 | RTC oscillator inputs | Supports 32.768 kHz crystal or external clock source for battery-backed real-time calendar with subsecond resolution. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator | Enables zero-wait-state execution from Flash at 100 MHz - eliminates instruction fetch stalls in closed-loop motor control firmware. |
| Batch Acquisition Mode (BAM) | Allows DMA-driven peripheral acquisition (ADC, SPI, I2C) while CPU sleeps in Stop mode - cuts average power in sensor hubs by >70%. |
| Adaptive Voltage Regulator | Supports 1.7–3.6 V operation with dynamic scaling - maintains performance across wide input ranges in battery-powered medical devices. |
| Embedded Trace Macrocell (ETM) | Enables non-intrusive real-time instruction trace via SWD - critical for debugging timing-critical ISR latency in industrial safety firmware. |
| CRC Calculation Unit | Hardware-accelerated CRC-32 generator - offloads checksum computation from CPU during firmware OTA updates or SDIO data transfers. |

FAQ
What is the maximum operating temperature range for STM32F411CEU6TR?
The STM32F411CEU6TR is rated for industrial operation from –40°C to +105°C ambient temperature, validated per ST's DS10314 Rev 8 specification. This rating applies to all electrical characteristics including Flash endurance, ADC linearity, and USB PHY functionality - confirmed across full voltage range (1.7–3.6 V) and load conditions.
Does STM32F411CEU6TR support USB device-only mode without external components?
Yes. STM32F411CEU6TR integrates a full-speed USB 2.0 OTG PHY with internal transceiver, enabling USB device mode using only PA11 (DP) and PA12 (DM) pins and standard 1.5 kΩ pull-up resistor. No external PHY, level shifter, or crystal is required for basic HID or CDC implementations.
How many independent PWM outputs can be generated simultaneously?
Up to 24 independent PWM outputs are achievable: six 16-bit timers (TIM3–TIM8) each support four complementary OC/OCN channels, and two 32-bit timers (TIM2/TIM5) provide four additional channels. All channels support dead-time insertion, fault protection, and synchronized update - verified in ST Application Note AN4013.
Is the 12-bit ADC capable of simultaneous sampling across multiple channels?
No. The single 12-bit ADC supports sequential sampling across up to 16 channels via hardware scan mode, but lacks true simultaneous sampling. For multi-channel synchronized acquisition, external analog front-ends or dual-ADC STM32 variants (e.g., F42x/F43x) are required - as documented in Section 3.29 of DS10314 Rev 8.
