STMicroelectronics STM32F411RCT7

Overview

STM32F411RCT7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 512 KB Flash, 128 KB SRAM, and USB OTG FS interface - deployed in motor control, medical equipment, and industrial PLCs requiring deterministic real-time response and integrated connectivity.

For engineers reviewing the STM32F411RCT7 datasheet, STM32F411RCT7 pinout, STM32F411RCT7 application, or STM32F411RCT7 equivalent, key selection criteria include ART Accelerator-enabled zero-wait-state flash execution, 12-bit 2.4 MSPS ADC with up to 16 channels, 11 timers (including six 16-bit and two 32-bit), low-power Stop mode down to 9 µA, and 77 5 V-tolerant I/Os for robust system interfacing.

Technical Context

The STM32F411RCT7 integrates an adaptive real-time accelerator (ART) that eliminates flash wait states at 100 MHz, enabling deterministic Dhrystone 2.1 performance of 125 DMIPS. Its memory subsystem includes 512 KB of embedded Flash with ECC support and 128 KB of SRAM, partitioned across multiple AHB buses for concurrent peripheral access.

Power architecture features three low-power modes - Stop (with Flash in Deep power-down, 9 µA typical), Standby (1.8 µA at 25 °C), and Run (100 µA/MHz) - managed by a multi-level voltage regulator and supply supervisors (POR/PDR/PVD/BOR). Clocking supports 4–26 MHz external crystal, internal 16 MHz RC, and 32 kHz RTC oscillator with calibration.

FAQ

What is the maximum operating temperature range for STM32F411RCT7?

The STM32F411RCT7 is rated for industrial temperature operation from –40 °C to +105 °C, verified per datasheet Table 14 (General operating conditions). This rating applies to all LQFP64 variants and is validated under full electrical specification across the range, including Flash programming, ADC accuracy, and USB OTG timing margins.

Does STM32F411RCT7 support external memory interfaces like SDRAM or NOR Flash?

No, the STM32F411RCT7 does not integrate FSMC (Flexible Static Memory Controller) or FMC peripherals. It supports only internal Flash and SRAM, plus SDIO for removable storage. External parallel memory expansion requires higher-pin-count variants like STM32F429xx or STM32F469xx with dedicated memory controllers.

How many USB endpoints does the integrated USB OTG FS controller support?

The USB OTG FS controller in STM32F411RCT7 supports 4 bidirectional endpoints (EP0–EP3), with EP0 reserved for control transfers and EP1–EP3 configurable for bulk, interrupt, or isochronous transfers. Endpoint buffer sizes are programmable up to 64 bytes per endpoint, and descriptors are managed in SRAM using standard USB device stack APIs.

Can the STM32F411RCT7 achieve 100 MHz CPU frequency with all peripherals active?

Yes - the ART Accelerator enables 100 MHz operation with zero-wait-state Flash execution even with multiple peripherals active. However, sustained 100 MHz operation requires VDD ≥ 2.7 V (per datasheet Section 6.3.1) and proper thermal management; at 1.7 V, max frequency is reduced to 84 MHz to maintain timing closure and voltage margin.
