Product details
Overview
STM32F411VET6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, delivering 125 DMIPS at 100 MHz, featuring 512 KB Flash, 128 KB SRAM, USB OTG FS controller with on-chip PHY, and 13 communication interfaces including 3×I²C, 3×USART, and 5×SPI/I²S. It targets real-time embedded control in motor drives, medical equipment, and industrial PLCs.
For engineers reviewing the STM32F411VET6TR datasheet, STM32F411VET6TR pinout, STM32F411VET6TR application, or STM32F411VET6TR equivalent, key selection criteria include its 100 MHz CPU frequency with ART Accelerator enabling zero-wait-state flash execution, 12-bit 2.4 MSPS ADC with up to 16 channels, low-power Stop mode down to 9 µA (Flash in Deep power down), and 77 5 V-tolerant I/Os for robust system interfacing.
Technical Context
The device integrates an adaptive real-time accelerator (ART Accelerator) that eliminates flash wait states across the full 1.7–3.6 V supply range and -40°C to +105°C operating temperature. Its memory subsystem includes 512 KB of embedded Flash with ECC support and 128 KB of SRAM, partitioned into multiple banks for concurrent access.
Power architecture supports dynamic efficiency via Batch Acquisition Mode (BAM) for sensor data capture during low-power operation, alongside three low-power modes-Stop (42 µA typical), Standby (1.8 µA), and VBAT RTC backup (1 µA)-all managed by integrated POR/PDR/PVD/BOR circuitry and dual oscillators (4–26 MHz HSE + 32 kHz LSE).

FAQ
What is the maximum operating temperature for STM32F411VET6TR?
The STM32F411VET6TR is rated for industrial temperature range: –40°C to +105°C ambient, validated per ST's DS10314 Rev 8 specification. This rating applies to the LQFP100 package under specified thermal conditions and voltage supply (1.7–3.6 V). Derating curves and junction temperature limits are provided in Section 6.3.1 of the datasheet.
Does STM32F411VET6TR support USB device-only mode without external PHY?
Yes - it integrates a full-speed USB 2.0 OTG controller with on-chip PHY, supporting device, host, and OTG roles without external transceivers. The PA11 (DP) and PA12 (DM) pins provide direct USB differential signaling compliant with USB 2.0 FS electrical specifications, confirmed in Section 3.27 and Table 8 of DS10314 Rev 8.
How many 5 V-tolerant I/O pins does STM32F411VET6TR have?
STM32F411VET6TR provides up to 77 5 V-tolerant I/O pins across its GPIO ports (PA–PI), as explicitly stated in the "Features" section of DS10314 Rev 8. Tolerance is guaranteed over the full operating temperature range and supply voltage (1.7–3.6 V), enabling direct interfacing with 5 V logic without level shifters.
Is the ART Accelerator enabled by default after reset?
No - the ART Accelerator is disabled by default after reset. It must be explicitly enabled via the ART_CTRL register (SYSCFG->MEMRMP[1]) and configured for prefetch and instruction cache. Enabling it is required to achieve zero-wait-state execution from Flash; this initialization step is documented in RM0383 Reference Manual Section 3.3.3 and AN4071 application note.
