Product details
Overview
STM32F411CCU6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 256 KB flash memory, 128 KB SRAM, and USB OTG FS interface. It integrates a 12-bit 2.4 MSPS ADC (16 channels), up to 11 timers including six 16-bit and two 32-bit units, and supports BAM for low-power sensor acquisition in industrial control systems.
For engineers reviewing the STM32F411CCU6TR datasheet, STM32F411CCU6TR pinout, STM32F411CCU6TR application, or STM32F411CCU6TR equivalent, key selection criteria include flash/SRAM size trade-offs, UFQFPN48 package constraints, USB OTG FS PHY integration, and 100 MHz real-time performance with ART Accelerator enabling zero-wait-state execution from flash.
Technical Context
The STM32F411CCU6TR implements an Arm Cortex-M4 core with hardware FPU and DSP instructions, coupled with ST's Adaptive Real-Time (ART) Accelerator that eliminates flash wait states at 100 MHz. Its memory subsystem includes 256 KB of embedded flash (not 512 KB - confirmed by device marking "CC" in Table 1 and ordering info) and 128 KB SRAM, with MPU support for secure task isolation.
Power architecture features dynamic efficiency line with Batch Acquisition Mode (BAM), enabling ultra-low-power peripheral operation while CPU remains in Stop mode. It supports three voltage ranges (1.7–3.6 V), includes POR/PDR/PVD/BOR, and offers multiple clock sources: 4–26 MHz HSE, 16 MHz HSI, and 32 kHz LSE/LSI - all validated for industrial temperature range (−40°C to +105°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU and DSP extensions; enables floating-point math and signal processing without external coprocessor. |
| Max Clock Frequency | 100 MHz; delivers 125 DMIPS (1.25 DMIPS/MHz) with ART Accelerator active - critical for real-time motor control loops. |
| Flash Memory | 256 KB; "CC" suffix per ST's ordering matrix (Table 1) - sufficient for bootloader + RTOS + application firmware in compact edge nodes. |
| SRAM | 128 KB; unified SRAM usable for stack, heap, DMA buffers, and cache-like data retention during low-power modes. |
| ADC | 12-bit, 2.4 MSPS, 16-channel; supports simultaneous sampling on multiple channels - essential for multi-sensor industrial monitoring. |
| USB Interface | USB 2.0 Full-Speed OTG with integrated PHY; eliminates need for external transceiver, reducing BOM and PCB area in portable diagnostics tools. |
| Package | UFQFPN48 (7 × 7 mm); 0.5 mm pitch, exposed thermal pad - optimized for thermal dissipation in space-constrained motor drives and HVAC controllers. |
Pinout & Package
STM32F411CCU6TR uses the UFQFPN48 package (ST part code A0B9), featuring 48 pins in a 7 × 7 mm body with exposed thermal pad (EP). Pin functions are defined per ST's DS10314 Rev 8 Section 4 ("Pinouts and pin description"), with dedicated VCAP_1/VCAP_2 pins for internal regulator decoupling and dual VDD/VSS pairs for analog/digital domain separation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA | Core & Analog Power Supply | Separate 1.7–3.6 V supplies enable noise-isolated ADC operation; VDDA must be ≥ VDD for valid analog performance. |
| VCAP_1, VCAP_2 | Internal Regulator Decoupling | Requires 2.2 µF ceramic capacitors to stabilize internal 1.2 V regulator - mandatory for reliable 100 MHz operation. |
| PA11, PA12 | USB DP/DM | Dedicated full-speed USB 2.0 differential pair with integrated transceiver - no external PHY needed. |
| NRST | Active-Low Reset Input | Asynchronous reset with internal pull-up; accepts 1.65–5.5 V logic - compatible with 3.3 V and 5 V system supervisors. |
| BOOT0 | Boot Mode Selection | High at power-up selects system memory bootloader; used for field firmware recovery via USART or USB DFU. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator | Enables zero-wait-state 100 MHz execution from flash - eliminates external SRAM dependency for deterministic real-time response. |
| Batch Acquisition Mode (BAM) | Allows peripherals (ADC, SPI, I2C) to operate autonomously in Stop mode while CPU sleeps - reduces average current to ~9 µA. |
| USB OTG FS with PHY | Integrated transceiver supports device/host/OTG roles - enables firmware updates via USB mass storage or CDC ACM without external ICs. |
| 96-bit Unique ID | Factory-programmed serial number accessible via system memory - used for secure device binding and license enforcement. |
| Temperature Sensor | Calibrated ±1.5°C accuracy across −40°C to +125°C - provides board-level thermal monitoring without external sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401CCU6 | Same UFQFPN48 package, Cortex-M4 core, but no FPU; 256 KB flash, 64 KB SRAM; lacks ART Accelerator and BAM. | Lower cost for non-FP math tasks; insufficient for real-time FFT-based vibration analysis or audio preprocessing. | Select when floating-point computation and ultra-low-power batch acquisition are not required. |
| STM32F412CEU6 | UFQFPN48, Cortex-M4 with FPU, 512 KB flash, 256 KB SRAM, adds AES crypto engine and Chrom-ART accelerator; no USB FS PHY (requires external transceiver). | Better for secure firmware updates and GUI rendering; USB host capability requires external PHY - increases BOM and layout complexity. | Select when cryptographic security or high-resolution display offloading is prioritized over integrated USB simplicity. |
Compared with STM32F412CEU6, STM32F411CCU6TR trades flash/SRAM headroom and crypto for integrated USB PHY and lower system-level power in always-on sensor nodes; versus STM32F401CCU6, it delivers deterministic 100 MHz performance and FPU-enabled signal processing at modest cost premium.

FAQ
What is the maximum operating temperature for STM32F411CCU6TR?
The STM32F411CCU6TR is qualified for industrial temperature range: −40°C to +105°C ambient. This rating is confirmed in Section 6.3.1 (General operating conditions) of DS10314 Rev 8, and applies to all UFQFPN48 variants including the "U6TR" tape-and-reel variant. Thermal derating begins above 105°C ambient per Section 7.7.
Does STM32F411CCU6TR support USB device mode without external components?
Yes. STM32F411CCU6TR integrates a full-speed USB 2.0 transceiver (PHY) on-die, supporting device, host, and OTG modes. Pins PA11 (DP) and PA12 (DM) connect directly to a USB Type-A receptacle with only series resistors (22 Ω recommended) and ESD protection - no external PHY or level shifter required.
How much flash memory does STM32F411CCU6TR actually have?
STM32F411CCU6TR contains 256 KB of embedded flash memory. The "CC" in the part number denotes 256 KB per ST's official device summary (Table 1, DS10314 Rev 8), distinct from "CE" (512 KB) and "RC" (256 KB with different peripheral set). This is verified in memory mapping (Section 5) and electrical characteristics (Section 6.3.12).
What debug interfaces are supported on STM32F411CCU6TR?
STM32F411CCU6TR supports Serial Wire Debug (SWD) and JTAG via dedicated SWDIO, SWCLK, and JTCK/JTMS/JTDI/JTDO pins. SWD is the recommended interface due to its 2-pin footprint and full debug capability; JTAG is retained for legacy tool compatibility. Both are enabled by default after reset.
