STMicroelectronics STM32F411CCY6TR

Overview

STM32F411CCY6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 256 KB Flash (per STM32F411xC family spec), 64 KB SRAM, and USB OTG FS controller. It integrates a 12-bit 2.4 MSPS ADC (16 channels), 11 timers including six 16-bit and two 32-bit units, and supports BAM for low-power sensor acquisition in industrial edge nodes.

For engineers reviewing the STM32F411CCY6TR datasheet, STM32F411CCY6TR pinout, STM32F411CCY6TR application, or STM32F411CCY6TR equivalent, key selection criteria include its WLCSP49 package footprint, 78 fast I/Os rated to 100 MHz, 77 5 V-tolerant pins, and verified operation across –40°C to +105°C ambient temperature.

Technical Context

The device implements an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 100 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its clock system includes dual oscillators - 4–26 MHz HSE and factory-trimmed 16 MHz HSI - plus 32 kHz LSE/LSI for RTC and low-power timing.

Power architecture features three low-power modes: Stop mode with 9 µA (Deep power down) and 42 µA (fast wakeup), Standby at 1.8 µA (no RTC), and dynamic efficiency line support via Batch Acquisition Mode (BAM) for sensor data burst capture without waking the core.

Key Specifications

Pinout & Package

STM32F411CCY6TR uses a 49-ball WLCSP (Wafer-Level Chip Scale Package) with 0.4 mm ball pitch and bottom-side I/O layout optimized for ultra-compact PCB designs. Ball assignment follows ST's standardized WLCSP49 mapping for STM32F411xC series.

FAQ

What is the maximum operating temperature for STM32F411CCY6TR?

The STM32F411CCY6TR is rated for industrial operation from –40°C to +105°C ambient temperature, as confirmed in Section 6.3.1 of DS10314 Rev 8. This rating applies to all WLCSP49-packaged variants in the STM32F411xC family and is validated under regulated voltage and thermal test conditions.

Does STM32F411CCY6TR support USB host functionality?

Yes - the integrated USB 2.0 full-speed OTG controller supports device, host, and on-the-go (OTG) modes. Hardware-level host negotiation (SRP/HNP) and embedded PHY eliminate need for external transceivers, enabling direct connection to USB keyboards, flash drives, or HID peripherals.

How many 5 V-tolerant I/O pins does STM32F411CCY6TR have?

It provides up to 77 5 V-tolerant I/O pins, as specified in the "Features" section of DS10314 Rev 8. These pins tolerate 5.5 V regardless of VDD level (1.7–3.6 V), allowing safe interfacing with legacy 5 V logic, sensors, and displays without external level-shifting circuitry.

Is the ART Accelerator enabled by default after reset?

Yes - the Adaptive Real-Time Accelerator is enabled by default upon power-on reset and remains active unless explicitly disabled via SYSCFG register configuration. It delivers zero-wait-state execution from Flash at all supported frequencies up to 100 MHz, improving code density and interrupt latency predictability.
