STMicroelectronics STM32F401VCH6

Overview

STM32F401VCH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, delivering 105 DMIPS at 84 MHz, featuring 256 KB Flash, 64 KB SRAM, and integrated USB 2.0 FS OTG controller with on-chip PHY. It supports 12-bit ADC (2.4 MSPS, up to 16 channels), 11 communication interfaces including 3×I²C, 3×USART, and 4×SPI, and operates across -40 °C to +105 °C in LQFP100 package - deployed in industrial motor control gateways requiring deterministic real-time response and low-power connectivity.

For engineers reviewing the STM32F401VCH6 datasheet, STM32F401VCH6 pinout, STM32F401VCH6 application, or STM32F401VCH6 equivalent, key selection criteria include ART Accelerator™-enabled zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 81 pins), sub-µA standby current (2.4 µA @25 °C), and hardware RTC with subsecond accuracy - all critical for battery-backed edge nodes and resource-constrained HMI platforms.

Technical Context

The STM32F401VCH6 integrates an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, enabling deterministic instruction fetch for time-critical control loops. Its memory protection unit (MPU) enforces privilege separation between firmware layers, while the dual-clock domain (HSI/HSI16 + HSE 4–26 MHz) supports robust clock failover in industrial environments.

Power architecture includes three low-power modes - Stop (42 µA typ), DeepStop (10 µA typ), and Standby (2.4 µA) - each with configurable Flash retention and wakeup sources. The USB OTG_FS controller implements full-speed device/host/OTG functionality using an embedded PHY, eliminating external transceiver components in portable diagnostic tools.

FAQ

Does STM32F401VCH6 support USB host mode?

Yes, the STM32F401VCH6 integrates a USB 2.0 Full-Speed OTG controller with on-chip PHY, supporting device, host, and OTG roles. Host mode requires external VBUS sensing and power switching circuitry per USB specification, but the silicon provides all necessary registers, descriptors, and endpoint buffers for class-compliant implementations such as USB HID or mass storage.

What is the maximum ADC sampling rate with all 16 channels enabled?

At 2.4 MSPS aggregate throughput, the 12-bit ADC achieves 150 kSPS per channel when all 16 channels are scanned sequentially in continuous mode. This assumes proper clock configuration (ADCCLK ≤ 36 MHz) and use of DMA to avoid CPU bottlenecks - verified in ST's AN4073 application note for multi-channel acquisition.

Can the ART Accelerator™ be disabled?

Yes, the ART Accelerator™ can be disabled via the FLASH_ACR register (ARTEN = 0). Disabling it increases Flash access latency (1 wait state at 84 MHz), reducing DMIPS by ~15%, but may simplify timing analysis in safety-critical applications where deterministic worst-case execution time (WCET) is prioritized over peak performance.

Is the STM32F401VCH6 pin-compatible with other STM32F401 variants?

No - the STM32F401VCH6 uses the LQFP100 package, while other variants like STM32F401CBU6 (UFQFPN48) and STM32F401CCU6 (UFQFPN48) have different pin counts and layouts. Pin compatibility exists only within the same package option (e.g., STM32F401VCT6 shares LQFP100 pinout but differs in Flash size and temperature grade).
