Product details
Overview
STM32F410CBU3TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, delivering 125 DMIPS at up to 100 MHz, featuring 128 KB flash, 32 KB SRAM, one 12-bit 2.4 MSPS ADC, one 12-bit DAC, and low-power LPTIM - deployed in industrial sensor nodes, portable medical monitors, and battery-powered IoT edge controllers.
For engineers reviewing the STM32F410CBU3TR datasheet, STM32F410CBU3TR pinout, STM32F410CBU3TR application, or STM32F410CBU3TR equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, 6 µA Stop-mode power consumption, 49 5 V-tolerant I/Os, and UFQFPN48 package compatibility with space-constrained PCB layouts.
Technical Context
The device integrates Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash memory, and Dynamic Efficiency Line architecture supporting 1.7–3.6 V operation across –40 °C to 105 °C. Its eBAM (enhanced Batch Acquisition Mode) optimizes burst ADC sampling while minimizing active time.
It features a multi-AHB bus matrix for concurrent peripheral access, embedded 96-bit unique ID, true random number generator (RNG), CRC calculation unit, and hardware RTC with subsecond accuracy and calendar function - all coordinated via NVIC with 96 interrupt channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 with FPU, 100 MHz max frequency, 125 DMIPS performance - enables real-time DSP and control algorithms without external coprocessor. |
| Memory | 128 KB flash (with ART accelerator), 32 KB SRAM, 512 B OTP - sufficient for secure boot, firmware updates, and dual-bank operation in field-deployed devices. |
| ADC | 1×12-bit, 2.4 MSPS, up to 16 channels - supports high-speed analog sensing in motor control feedback or multi-sensor data acquisition. |
| DAC | 1×12-bit, buffered output - provides precise analog waveform generation for calibration signals or actuator biasing. |
| Power Modes | Run: 89 µA/MHz; Stop (deep power down): 6 µA @25 °C; Standby: 2.4 µA @25 °C - extends battery life in always-on edge nodes. |
| I/O | Up to 49 5 V-tolerant pins, 45 fast I/Os @100 MHz - simplifies level-shifting design and supports mixed-voltage peripheral interfacing. |
| Timers | 9 timers including LPTIM (available in Stop mode), advanced TIM1, and SysTick - enables precision PWM, encoder counting, and ultra-low-power wake-up scheduling. |
| Communication | 3×I²C (1×fast-mode 1 MHz), 3×USART (2×12.5 Mbit/s), 3×SPI/I²S - covers sensor fusion (I²C), wireless modem control (USART), and audio/data streaming (SPI/I²S). |
Pinout & Package
STM32F410CBU3TR uses the UFQFPN48 (7 × 7 mm, 0.5 mm pitch) package with exposed thermal pad, compliant with ECOPACK2 environmental standards. Pin count is 48, with 37 user I/Os plus power/ground/reset/clock functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core & I/O supply / ground | Dual power domains: VDD powers core/SRAM/flash; VSS reference for all digital/analog circuits - requires separate decoupling per datasheet layout guidelines. |
| VCAP_1 | Internal regulator capacitor connection | Must be connected to 2.2 µF ceramic capacitor to stabilize internal 1.2 V regulator - failure causes boot failure or erratic reset behavior. |
| NRST | Active-low reset input | Asynchronous reset pin with Schmitt trigger; accepts 1.65–5.5 V logic - enables external supervisory IC or push-button reset integration. |
| PA0–PA15, PB0–PB15, PC13–PC15 | General-purpose I/Os | 49 total 5 V-tolerant GPIOs; many support multiple alternate functions (e.g., USART2_TX on PA2, SPI1_SCK on PA5) - enables flexible peripheral mapping. |
| OSC_IN / OSC_OUT | HSE crystal oscillator interface | Supports 4–26 MHz external crystal - required for precise timing in USB, RTC, or communication protocols demanding low jitter. |
| BOOT0 | Boot mode selection | High at reset forces system memory bootloader activation via USART1 - used for field firmware recovery without debugger. |
Key Features
| Feature | Design Value |
|---|---|
| eBAM (enhanced Batch Acquisition Mode) | Reduces CPU wake-up overhead during periodic ADC bursts - cuts average current by >30% in sensor polling applications. |
| ART Accelerator | Enables 0-wait-state execution from flash at 100 MHz - eliminates need for external RAM caching in cost-sensitive designs. |
| LPTIM (Low-Power Timer) | Operates in Stop mode with 32 kHz LSE clock - allows precise wake-up intervals (e.g., every 100 ms) without full MCU restart. |
| 5 V-tolerant I/Os | 49 pins tolerate 5 V inputs regardless of VDD (1.7–3.6 V) - eliminates level shifters when interfacing with legacy 5 V sensors or logic. |
| True Random Number Generator (RNG) | FIPS-compliant entropy source - enables secure key generation for TLS handshakes or firmware signature verification. |
| Embedded RTC with calendar | Hardware subsecond counter + calendar registers - maintains accurate timekeeping during Standby mode using VBAT (1 µA @25 °C). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401CCU6 | Same UFQFPN48 package, but 84 MHz Cortex-M4, 256 KB flash, no DAC, higher run current (110 µA/MHz) | Lacks integrated DAC and has weaker low-power performance (Stop mode: 15 µA vs. 6 µA) | Choose when larger flash and higher compute headroom are needed, and DAC/ultra-low-power are not required. |
| STM32L431CCU6 | Cortex-M4 with FPU, 80 MHz, 256 KB flash, ultra-low-power architecture (Stop mode: 2.5 µA), but no full-speed USB or 100 MHz timers | Optimized for energy-per-cycle over peak speed; lacks 100 MHz timer and high-speed USART (12.5 Mbit/s) | Prefer for battery lifetime-critical applications where 100 MHz real-time response is unnecessary. |
Compared with STM32F410CBU3TR, STM32F401CCU6 trades lower power efficiency for greater flash capacity and clock headroom, while STM32L431CCU6 achieves deeper sleep current at the expense of maximum peripheral speed and DAC integration - making STM32F410CBU3TR optimal for balanced performance, analog integration, and moderate battery life.

FAQ
What is the maximum operating temperature range for STM32F410CBU3TR?
The STM32F410CBU3TR is rated for industrial operation from –40 °C to +105 °C ambient temperature, validated per DS11144 Rev 8 Section 6.3.1. This rating applies to the UFQFPN48 package variant and supports deployment in enclosed enclosures without forced cooling.
Does STM32F410CBU3TR support USB device functionality?
No, STM32F410CBU3TR does not integrate a USB peripheral. Unlike higher-tier F4 devices (e.g., F405/F407), it omits USB OTG and relies on external USB-to-UART bridges or BLE/Wi-Fi modules for host connectivity - confirmed in Table 2 and Section 3.22 of DS11144.
How many ADC channels are accessible in the UFQFPN48 package?
The UFQFPN48 package exposes 16 ADC input channels (ADC1_IN0 through ADC1_IN15) across GPIO pins PA0–PA7, PB0–PB1, PC0–PC5, and PC10–PC11 - matching the full 16-channel capability documented in Section 3.27 and Table 9 of DS11144.
Is the VCAP_1 capacitor mandatory for reliable operation?
Yes, a 2.2 µF X7R ceramic capacitor must be placed between VCAP_1 and VSS, as specified in Section 7.2 and Figure 13 of DS11144. Omission causes internal regulator instability, leading to unpredictable resets or failure to exit reset - this is not optional for production designs.
