STMicroelectronics STM32F071V8H6

Overview

STM32F071V8H6 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, 1.0 µs), dual 12-bit DAC, two analog comparators, and RTC with calendar support. It targets cost-sensitive industrial control and smart sensor nodes requiring low-power operation and mixed-signal integration.

For engineers reviewing the STM32F071V8H6 datasheet, STM32F071V8H6 pinout, STM32F071V8H6 application, or STM32F071V8H6 equivalent, key selection criteria include Flash/SRAM size, 5V-tolerant I/O count (up to 68 pins), VDDIO2 independent supply capability (1.65–3.6 V), USB-less communication interface mix (4× USART, 2× I²C, 2× SPI), and embedded capacitive touch sensing (24 channels).

Technical Context

The STM32F071V8H6 implements a single-core Arm Cortex-M0 CPU with Harvard bus architecture, supporting Thumb-2 instruction set and NVIC-based interrupt handling. Its clock system integrates four internal oscillators (HSI48, HSI8, LSI, LSE) plus external 4–32 MHz crystal and 32 kHz RTC oscillator with calibration - enabling precise timing across sleep/active modes.

Peripheral interconnect uses AHB/APB buses with DMA-driven data movement across ADC, DAC, USART, and SPI. The device supports boot from system memory, main Flash, or SRAM, and includes CRC calculation unit, programmable voltage detector (PVD), and hardware parity on SRAM for functional safety compliance in basic industrial applications.

FAQ

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

The STM32F071V8H6 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 datasheet Section 6.3.1; below 2.4 V, maximum frequency scales linearly down to 24 MHz at 2.0 V. This voltage/frequency scaling ensures safe operation under brown-out conditions without software intervention.

Does this MCU support hardware cryptographic acceleration?

No, the STM32F071V8H6 does not include hardware crypto engines (AES, SHA, PKA). It relies on software libraries for cryptographic operations. For secure boot or TLS offload, ST recommends upgrading to STM32G0 or STM32L5 series, which integrate AES-128/256 accelerators and true random number generators compliant with NIST SP800-90B.

Can the internal 12-bit DAC drive a 50 Ω load directly?

No - the DAC output drives only high-impedance loads (≥5 kΩ recommended). Driving 50 Ω requires an external op-amp buffer. Datasheet Section 6.3.17 specifies DAC output impedance as ~15 kΩ and maximum sink/source current as ±1 mA; exceeding this causes gain error and distortion above 10 kHz.

Is the LQFP64 package of STM32F071V8H6 pin-compatible with other STM32F071 variants?

Yes - all STM32F071x8 devices in LQFP64 share identical pinout and footprint, including STM32F071CB and STM32F071RB. Differences are limited to Flash size (64 KB vs. 128 KB) and peripheral enablement (e.g., some features disabled in smaller Flash variants), but pin functions and electrical characteristics remain consistent across the LQFP64 family.
