Product details
Overview
STM32F071C8T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller in LQFP48 package, operating up to 48 MHz with 64 KB Flash and 16 KB SRAM (HW parity), integrated 12-bit ADC (16-channel, 1.0 µs conversion), dual 12-bit DAC, and 2 analog comparators - deployed in industrial sensor nodes requiring deterministic real-time control and low-power operation.
For engineers reviewing the STM32F071C8T6 datasheet, STM32F071C8T6 pinout, STM32F071C8T6 application, or STM32F071C8T6 equivalent, key selection criteria include its 48 MHz CPU clock, 5V-tolerant I/Os (up to 39 pins), 2.0–3.6 V supply range, RTC with calendar and alarm, and support for USB-less device programming via SWD debug interface.
Technical Context
The STM32F071C8T6 implements a single-core Arm Cortex-M0 processor with Harvard bus architecture, tightly coupled NVIC supporting 32 interrupt channels and 4 priority levels. Its memory subsystem includes 64 KB of Flash with 24-bit address space, 16 KB SRAM with hardware parity checking, and dedicated 32-bit CRC calculation unit for firmware integrity verification.
Clock management integrates four independent oscillators: 4–32 MHz HSE crystal input, 32 kHz LSE for RTC, 8 MHz HSI with PLL (×6 → 48 MHz), and factory-trimmed 48 MHz HSI48 oscillator for USB-free synchronous peripheral timing - all managed by RCC with dynamic clock gating per peripheral.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 32-bit RISC, 48 MHz max frequency - enables deterministic real-time task scheduling with <100 ns interrupt latency. |
| Flash Memory | 64 KB, 24-bit addressing, 10K write/erase cycles - sufficient for bootloader + application firmware with field-upgrade capability. |
| SRAM | 16 KB with hardware parity - detects single-bit errors in real time for safety-critical data buffers and stack operations. |
| ADC | 12-bit, 1.0 µs conversion time, 16-channel multiplexed input - supports simultaneous sampling of temperature, voltage, and current sensors at ≥1 MSPS aggregate rate. |
| DAC | Two 12-bit buffered outputs with 1 µs settling time - drives analog control signals (e.g., bias voltage, reference level) without external op-amps. |
| I/O Pins | 39 GPIOs, 37 with 5V tolerance, 2 with independent VDDIO2 supply (1.65–3.6 V) - interfaces directly with legacy 5V logic and mixed-voltage peripherals. |
| Low-Power Modes | Sleep (CPU off, peripherals active), Stop (1.3 µA @ 3.3 V), Standby (0.5 µA) - extends battery life in portable instrumentation and wireless sensor endpoints. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072C8T6 | Same package and pinout; adds USB 2.0 FS device interface and CRC accelerator - requires additional 3.3 V USB PHY supply. | Required where native USB device connectivity (e.g., HID, CDC) replaces UART-to-USB bridges. | Select when USB enumeration and descriptor handling are mandatory; avoid if board space or BOM cost must be minimized. |
| STM32F030F4P6 | Lower-cost LQFP20 variant with 16 KB Flash, 4 KB SRAM, no DAC or TSC, and only 15 GPIOs - lacks HW parity and advanced timers. | Suitable for simple LED control or relay actuation where analog features and capacitive sensing are unnecessary. | Choose for ultra-low-cost entry-level control tasks; not suitable for sensor fusion or precision analog signal chains. |
Compared with STM32F072C8T6, the STM32F071C8T6 trades USB capability for lower system complexity and reduced power consumption in non-USB applications; versus STM32F030F4P6, it delivers 4× more Flash, full analog subsystems, and industrial-grade reliability features at modest BOM premium.

FAQ
Does STM32F071C8T6 support USB device functionality?
No. The STM32F071C8T6 lacks an integrated USB transceiver and does not support native USB device operation. It provides UART, SPI, and I2C interfaces for external USB bridge ICs. For USB-capable variants, consider the STM32F072C8T6, which shares identical pinout and package but adds USB 2.0 Full-Speed device support.
What is the maximum operating frequency of the internal HSI48 oscillator?
The internal HSI48 oscillator runs at a fixed 48 MHz and is factory-trimmed to ±2% accuracy over temperature and voltage. It serves as the clock source for USB-less synchronous peripherals (e.g., SPI, I2C, USART) and can feed the system clock directly or via prescaler - eliminating need for external crystal in many timing-tolerant applications.
How many I/O pins support 5V tolerance on STM32F071C8T6?
37 of the 39 GPIO pins on the STM32F071C8T6 are 5V tolerant when VDD is ≥2.0 V. Pins PC13, PC14, and PC15 are excluded from 5V tolerance. This allows direct interfacing with 5V logic families (e.g., TTL, CMOS) without external level-shifting circuitry in mixed-voltage systems.
Is hardware parity checking available on both Flash and SRAM?
Hardware parity checking is implemented only on the 16 KB SRAM - detecting and signaling single-bit errors via the PCE (Parity Check Error) flag in the SYSCFG_MEMRMP register. Flash memory uses ECC only in higher-series STM32 devices; the F071 relies on software CRC (via dedicated CRC unit) for Flash integrity verification during boot or firmware updates.
