Product details
Overview
STM32F410CBU3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 128 KB flash, 32 KB SRAM, and integrated 12-bit ADC (2.4 MSPS), 12-bit DAC, and low-power timer-designed for compact industrial sensor nodes and battery-powered edge devices requiring real-time signal processing and sub-µA standby operation.
For engineers reviewing the STM32F410CBU3 datasheet, STM32F410CBU3 pinout, STM32F410CBU3 application, or STM32F410CBU3 equivalent, key selection criteria include its 1.7–3.6 V supply range, -40 °C to 105 °C extended temperature grade, 6 µA Stop mode current (deep power-down), ART Accelerator™ enabling zero-wait-state flash execution, and 49 5 V-tolerant I/Os in UFQFPN48 package.
Technical Context
The STM32F410CBU3 implements an Arm Cortex-M4 core with hardware FPU and Memory Protection Unit (MPU), paired with ST's Adaptive Real-Time (ART) Accelerator™ to eliminate flash wait states at 100 MHz. Its clock system integrates four oscillators: 4–26 MHz HSE, 16 MHz factory-trimmed HSI, 32 kHz LSE for RTC, and calibrated 32 kHz LSI.
Power architecture supports five low-power modes: Run, Sleep, Stop (with flash retention or deep power-down), Standby, and VBAT-only RTC operation. The device features eBAM (enhanced Batch Acquisition Mode) for ultra-low-power sensor data acquisition and includes a true random number generator (RNG), CRC unit, and 96-bit unique ID.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401CCU6 | No FPU, 84 MHz max, no LPTIM, lower ADC sample rate (2.4 MSPS → 2.0 MSPS), same 128 KB/32 KB memory | Lacks hardware floating-point for intensive math; unsuitable for real-time FOC or FFT-based sensor analytics | Select when cost sensitivity outweighs need for FPU or ultra-low-power timers. |
| STM32L432KCU6 | Cortex-M4 with FPU, 80 MHz, 256 KB flash, 64 KB SRAM, but only 10-bit ADC (1 MSPS), no DAC, higher Stop mode current (300 nA vs 6 µA) | Optimized for ultra-low-power sleep, not high-speed analog capture; lacks DAC for calibration outputs | Prefer for sub-1 µA average current designs where analog precision is secondary to energy harvesting compatibility. |
Compared with STM32F410CBU3, STM32F401CCU6 trades FPU and low-power timers for lower BOM cost, while STM32L432KCU6 prioritizes nanowatt sleep over analog throughput-making STM32F410CBU3 optimal for balanced real-time + low-power embedded control.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F410CBU3 achieves 100 MHz maximum CPU frequency using its Arm Cortex-M4 core with ST's ART Accelerator™, which caches flash instruction fetches to eliminate wait states. This requires enabling the prefetch buffer and instruction cache; measured performance is 125 DMIPS at 100 MHz under Dhrystone 2.1 benchmark conditions.
Does STM32F410CBU3 support USB or Ethernet connectivity?
No, the STM32F410CBU3 does not integrate USB or Ethernet MAC/PHY peripherals. It provides up to 3x USARTs (including ISO 7816, LIN, IrDA), 3x I²C, and 3x SPI/I²S interfaces. For USB connectivity, external PHY or bridge ICs (e.g., CP2102, FT232H) must be used with GPIO or USART resources.
What are the supported low-power modes and their typical current draw?
It supports Run (89 µA/MHz), Sleep, Stop (6 µA typ @25 °C in deep power-down), Standby (2.4 µA @25 °C), and VBAT-only RTC modes. Stop mode retains SRAM and register content with fast wake-up (~3.5 µs), while Standby disables all clocks except RTC and offers lowest current for calendar-critical applications.
Is the STM32F410CBU3 pin-compatible with other STM32F4 packages?
No-STM32F410CBU3 uses UFQFPN48 (7×7 mm), whereas STM32F401/405/407 variants use LQFP64, LQFP100, or UFBGA100 packages. Pin mapping differs significantly across families; migration requires PCB redesign and firmware adaptation due to peripheral register layout and clock tree variations.
