STMicroelectronics STM32F410CBT3

Overview

STM32F410CBT3 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, 100 MHz max CPU frequency, 128 KB flash, 32 KB SRAM, and integrated peripherals including 1×12-bit 2.4 MSPS ADC, 1×12-bit DAC, 9 timers (including LPTIM), and 9 communication interfaces (3×I²C, 3×USART, 3×SPI/I²S). It targets low-power industrial sensor nodes and compact motor-control edge devices operating from 1.7–3.6 V.

For engineers reviewing the STM32F410CBT3 datasheet, STM32F410CBT3 pinout, STM32F410CBT3 application, or STM32F410CBT3 equivalent, key selection criteria include its 6 µA Stop-mode power consumption, eBAM-enabled batch acquisition for sensor data aggregation, 49 5 V-tolerant I/Os, and ECOPACK2-compliant UFQFPN48 package.

Technical Context

The STM32F410CBT3 implements an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from flash at 100 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its dynamic efficiency architecture supports three low-power modes-Stop (6 µA), Standby (2.4 µA), and VBAT RTC operation-with calibrated 32 kHz RC and external 4–26 MHz crystal oscillator support.

Peripherals are organized via a multi-AHB bus matrix with 16-stream DMA supporting burst transfers and FIFO buffering. The core integrates a True Random Number Generator (TRNG), 96-bit unique ID, CRC calculation unit, and subsecond-accurate RTC with hardware calendar-enabling time-stamped sensor logging and secure boot in resource-constrained deployments.

FAQ

What is the maximum operating frequency and associated power supply range for the STM32F410CBT3?

The STM32F410CBT3 operates at up to 100 MHz across its full 1.7–3.6 V supply range. At 1.7 V, it achieves 100 MHz only with ART Accelerator enabled and prefetch enabled; at 3.6 V, it sustains 100 MHz with or without prefetch. This scalability allows consistent real-time performance across wide-input industrial power rails.

Does the STM32F410CBT3 support hardware cryptographic acceleration?

No, the STM32F410CBT3 does not integrate dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries for encryption; however, its True Random Number Generator (TRNG) provides entropy for secure key generation, and the 96-bit unique ID supports device authentication in lightweight protocols.

How many communication interfaces can operate simultaneously without resource conflict?

All 9 communication interfaces-including 3×I²C, 3×USART, and 3×SPI/I²S-can operate concurrently. The multi-AHB bus matrix and 16-stream DMA controller prevent bus contention, and alternate function remapping (Table 10) allows flexible pin assignment to avoid physical pin conflicts in dense PCB layouts.

What is the purpose of the VCAP_1 capacitor, and what value is required?

The VCAP_1 capacitor stabilizes the internal voltage regulator's output. Per DS11144 Rev 8 Section 6.3.2, a 2.2 µF ±20% ceramic capacitor with X7R dielectric must be placed between VCAP_1 and VSS, located within 5 mm of the pin. Failure to meet this requirement risks unstable core voltage and unpredictable reset behavior under load transients.
