STMicroelectronics STM32F401VCH7

Overview

STM32F401VCH7 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, one 12-bit 2.4 MSPS ADC (16 channels), and 11 communication interfaces including USB OTG FS, SDIO, I²C, USART, and SPI. It targets embedded control in industrial HMI, sensor hubs, and portable medical devices requiring real-time processing and low-power operation.

For engineers reviewing the STM32F401VCH7 datasheet, STM32F401VCH7 pinout, STM32F401VCH7 application, or STM32F401VCH7 equivalent, key selection criteria include its ART Accelerator™ enabling zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 81 pins), sub-µA standby current (2.4 µA @25 °C), and integrated RTC with hardware calendar - all validated for operation across -40 °C to 105 °C.

Technical Context

The STM32F401VCH7 implements an Arm Cortex-M4 core with single-precision FPU and Memory Protection Unit (MPU), paired with the Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states via instruction prefetch and branch cache. Its clock system integrates four oscillators: 4–26 MHz HSE, 32 kHz LSE for RTC, 16 MHz factory-trimmed HSI, and 32 kHz calibrated LSI.

Power architecture supports three low-power modes - Stop (42 µA typ), Standby (2.4 µA), and VBAT-powered RTC - with POR/PDR/PVD/BOR supervision and dual VCAP capacitor regulation. Peripheral interconnect uses a multi-AHB bus matrix, enabling concurrent DMA transfers (16-stream controller) and nested interrupt handling (NVIC) without CPU intervention.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F401VCH7 achieves 84 MHz maximum CPU frequency using its internal PLL, which multiplies the HSE (4–26 MHz) or HSI (16 MHz) clock source. The ART Accelerator™ enables zero-wait-state execution from Flash at this speed by caching instructions and prefetching branches, verified in DS9716 Rev 11 Section 3.2.

Does STM32F401VCH7 support USB device mode without an external crystal?

Yes - the STM32F401VCH7 supports USB full-speed device mode using its internal 48 MHz RC oscillator (HSI48), eliminating the need for an external 8/12 MHz crystal. This is confirmed in Section 3.26 of DS9716 Rev 11 and requires enabling the HSI48 clock and configuring the USB clock prescaler.

How many ADC channels are available and what is their effective resolution?

The device integrates one 12-bit ADC with up to 16 external input channels. At 2.4 MSPS sampling rate, it maintains ±1 LSB integral nonlinearity (INL) and differential nonlinearity (DNL), as specified in Table 66 and Figure 107 of DS9716 Rev 11, ensuring true 12-bit precision under nominal conditions.

What debug interfaces are supported and what are their physical requirements?

STM32F401VCH7 supports Serial Wire Debug (SWD) and JTAG via dedicated SWDIO/SWCLK and TMS/TCK/TDO/TDI pins. SWD requires only two pins and is recommended for production; JTAG needs five pins and supports boundary scan. Both interfaces operate at VDD voltage (1.7–3.6 V) and require appropriate pull-ups per Section 3.30 of the datasheet.
