STMicroelectronics STM32F071V8T6TR

Overview

STM32F071V8T6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller in LQFP64 package, operating up to 48 MHz with 64 KB Flash, 16 KB SRAM (HW parity), and integrated peripherals including 12-bit ADC (16-channel), dual 12-bit DAC, two analog comparators, and capacitive touch sensing - deployed in industrial HMI panels requiring low-power operation and precise analog signal acquisition.

For engineers reviewing the STM32F071V8T6TR datasheet, STM32F071V8T6TR pinout, STM32F071V8T6TR application, or STM32F071V8T6TR equivalent, key selection criteria include Flash/SRAM size, 5V-tolerant I/O count (up to 68 pins), RTC+VBAT support, and dual DAC channel availability for sensor calibration and actuator control.

Technical Context

This MCU implements a single-cycle Cortex-M0 core with hardware divide and Thumb-2 instruction set, paired with a dedicated CRC calculation unit and programmable voltage detector (PVD) for system-level fault detection. Its clock architecture integrates four independent oscillators: 4–32 MHz HSE, 32 kHz LSE for RTC, 8 MHz HSI with PLL, and factory-trimmed 48 MHz HSI48 for USB-free high-accuracy timing.

The peripheral subsystem includes a 7-channel DMA controller supporting memory-to-peripheral transfers, one advanced-control timer (TIM1) for six-channel PWM generation, and four USARTs - two with ISO7816, LIN, IrDA, and auto-baud detection - enabling robust serial communication in metering and motor control systems.

FAQ

What is the maximum operating frequency and corresponding supply voltage range?

The STM32F071V8T6TR operates at up to 48 MHz across its full VDD range of 2.0–3.6 V. At 48 MHz, minimum VDD is 2.4 V per electrical characteristics (Section 6.3.1). The internal 48 MHz HSI48 oscillator is factory-trimmed to ±2% accuracy and requires no external crystal, enabling rapid startup and reduced BOM cost.

Does this MCU support hardware cryptographic acceleration or secure boot?

No. The STM32F071V8T6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot features. It relies on software-based security primitives and external secure elements for authentication or encryption. For secure boot capability, consider STM32G0 or STM32L5 series devices with TRNG and AES-256 engines.

How many I/O pins support independent VDDIO2 supply, and what is their voltage range?

Nineteen I/O pins support independent VDDIO2 supply ranging from 1.65 V to 3.6 V, enabling mixed-voltage interfacing with low-voltage peripherals (e.g., 1.8 V sensors or memory) while maintaining full 3.3 V operation on other ports. These pins are designated in the datasheet as "VDDIO2-capable" and require separate decoupling from VDD.

Is the internal 48 MHz oscillator suitable for driving a 12-bit ADC at full speed?

Yes. The HSI48 oscillator is qualified for use with the ADC's synchronous clock input (ADCCLK), supporting up to 14 MHz ADC clock (fADC) - sufficient for 1 MSPS sampling at 12-bit resolution. Datasheet Table 57 confirms ADC performance specifications are guaranteed with HSI48 as clock source under standard operating conditions.
