STMicroelectronics STM32F410CBU6

Overview

STM32F410CBU6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, 100 MHz max clock, 128 KB flash, 32 KB SRAM, and integrated 12-bit ADC (2.4 MSPS), 12-bit DAC, and low-power timer (LPTIM). It operates from 1.7–3.6 V across –40 °C to 105 °C and targets battery-powered sensor nodes and compact industrial controllers requiring deterministic real-time response and ultra-low standby current (2.4 µA).

For engineers reviewing the STM32F410CBU6 datasheet, STM32F410CBU6 pinout, STM32F410CBU6 application, or STM32F410CBU6 equivalent, key selection criteria include ART Accelerator-enabled zero-wait-state flash execution, eBAM for energy-efficient batch data acquisition, 49 5 V-tolerant I/Os, and dual low-power modes (6 µA Stop deep power-down, 2.4 µA Standby) - critical for portable instrumentation and always-on edge sensing.

Technical Context

The STM32F410CBU6 implements a single-core Arm Cortex-M4 with FPU and Adaptive Real-Time (ART) Accelerator, enabling deterministic 100 MHz operation from internal flash without wait states. Its memory subsystem includes 128 KB embedded flash, 32 KB SRAM, and 512 bytes OTP - all accessible via multi-AHB bus matrix for concurrent peripheral access.

Power architecture integrates POR/PDR/PVD/BOR supervision, dual oscillators (4–26 MHz HSE + 32 kHz LSE), and three low-power modes (Stop, Standby, VBAT RTC). The 12-bit ADC supports up to 16 channels at 2.4 MSPS with hardware oversampling, while the 12-bit DAC provides rail-to-rail output with configurable trigger sources.

FAQ

What is the maximum operating temperature range for STM32F410CBU6?

The STM32F410CBU6 is qualified for industrial operation from –40 °C to +105 °C ambient temperature, as specified in DS11144 Rev 8 Section 6.3.1. This rating applies to the UFQFPN48 package under defined thermal conditions and ensures reliable flash programming, SRAM retention, and analog performance across the full range.

Does STM32F410CBU6 support USB connectivity?

No, the STM32F410CBU6 does not integrate a USB peripheral. Unlike higher-pin-count F4 variants (e.g., STM32F407), it omits USB OTG and relies on UART, SPI, or I²C for host/device communication. External USB-UART bridges (e.g., CP2102) are commonly used in designs requiring USB debug or data transfer.

How many communication interfaces can operate simultaneously?

All nine communication interfaces - including 3×I²C, 3×USART, and 3×SPI/I²S - share dedicated APB1/APB2 clocks and DMA resources but have independent control registers. Simultaneous operation is supported provided clock tree configuration avoids conflicts (e.g., no two peripherals assigned same APB prescaler) and DMA stream allocation prevents contention, as confirmed in RM0383 Reference Manual Section 9.3.3.

Is the 12-bit DAC output buffered?

Yes, the integrated 12-bit DAC features an internal output buffer that drives rail-to-rail voltage with ≤1 µs settling time, as documented in DS11144 Section 6.3.24. The buffer eliminates external op-amp requirements for moderate-load applications (< 10 kΩ), though external amplification is needed for low-impedance or high-current loads.
