Product details
Overview
STM32F071C8T6TR 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 4 USARTs supporting LIN, IrDA, and ISO7816 - used in industrial sensor nodes requiring low-power real-time control and serial protocol bridging.
For engineers reviewing the STM32F071C8T6TR datasheet, STM32F071C8T6TR pinout, STM32F071C8T6TR application, or STM32F071C8T6TR equivalent, key selection criteria include Flash/SRAM size, 5V-tolerant I/O count (up to 39 pins), RTC+backup register support, and dual DAC channel availability for analog waveform generation in cost-sensitive embedded systems.
Technical Context
The device implements a single-cycle Cortex-M0 core with NVIC, SW-DP debug interface, and hardware CRC unit. It integrates a flexible clock system featuring HSI48 (48 MHz, auto-trimmed), HSE (4–32 MHz), LSE (32.768 kHz for RTC), and PLL for precise frequency synthesis.
Power architecture supports three low-power modes (Sleep, Stop, Standby) with VBAT backup for RTC and registers, programmable voltage detector (PVD), and independent VDDIO2 supply (1.65–3.6 V) for partial I/O voltage scaling - enabling mixed-voltage interfacing in battery-powered applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F070F6P6 | 32 KB Flash, no DAC, no RTC calendar, 16 KB SRAM - smaller memory and reduced analog feature set. | Suitable for simpler control tasks without time-stamped logging or analog output requirements. | Select when cost sensitivity outweighs need for dual DAC or calendar RTC functionality. |
| STM32F072CBT6 | 128 KB Flash, USB 2.0 FS device, same peripherals but adds crystal-less USB capability. | Required for host-facing USB connectivity (e.g., HID keyboard/mouse, CDC device). | Choose when native USB device interface is mandatory and board space allows LQFP48 or LQFP64 package. |
Compared with STM32F071C8T6TR, STM32F070F6P6 sacrifices DAC and calendar RTC for lower cost, while STM32F072CBT6 adds USB but increases BOM complexity - making the F071C8T6TR optimal for non-USB, dual-analog-output industrial edge nodes.

FAQ
What is the maximum operating frequency and supported voltage range?
The STM32F071C8T6TR operates at up to 48 MHz and supports a digital supply voltage (VDD) range of 2.0 V to 3.6 V, with analog supply (VDDA) matching VDD up to 3.6 V. Its internal 48 MHz oscillator is auto-trimmed using external synchronization, ensuring ±1% accuracy without external crystal for many timing-critical applications.
Does this MCU support hardware encryption or secure boot?
No, the STM32F071C8T6TR does not include hardware cryptographic accelerators or secure boot features. It lacks AES, PKA, or TRNG modules found in higher-series STM32 devices (e.g., G0, L5, H7). Security relies on software-based implementations and external secure elements if required.
How many I/O pins are 5V tolerant, and which packages support them?
Up to 39 I/O pins are 5V tolerant on the STM32F071C8T6TR in LQFP48 package. This includes all pins except those designated for analog functions (e.g., VREF+, VREF−, VBAT, VDDA, VSSA) and specific debug pins (SWDIO, SWCLK). Tolerance is guaranteed per ST's electrical characteristics table (Section 6.3.14).
Can the internal 12-bit DAC drive external loads directly?
The internal DAC outputs (DAC1_OUT, DAC2_OUT) can source/sink up to ±5 mA with rail-to-rail swing (0–VDD), but output impedance is ~15 kΩ. For driving capacitive loads >100 pF or resistive loads <5 kΩ, an external op-amp buffer is recommended to maintain linearity and settling time specifications per datasheet Table 60.
