STMicroelectronics STM32C011F6U6TR

Overview

STM32C011F6U6TR from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB flash, 6 KB SRAM, 48 MHz max CPU frequency, 12-bit ADC (0.4 µs conversion), and dual USARTs supporting LIN/IrDA/ISO7816 - deployed in industrial sensor nodes requiring low-power operation and secure firmware updates.

For engineers reviewing the STM32C011F6U6TR datasheet, STM32C011F6U6TR pinout, STM32C011F6U6TR application, or STM32C011F6U6TR equivalent, key selection criteria include its 5 V-tolerant I/Os, PSA Level 3/SESIP3 security certification, 2–3.6 V supply range, and UFQFPN20 package compatibility with space-constrained PCB layouts.

Technical Context

This MCU integrates a memory protection unit (MPU) and securable flash area for firmware integrity enforcement, alongside hardware parity on SRAM and CRC calculation unit for data path reliability. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 48 MHz RC oscillator - enabling precise timing without external crystals in cost-sensitive designs.

The peripheral interconnect supports flexible DMA mapping across 3 channels and concurrent use of SPI/I²S via shared pins. All 18 GPIOs are 5 V-tolerant and mappable to external interrupt vectors, while the RTC includes calendar functionality and alarm - critical for time-stamped event logging in battery-powered edge devices.

FAQ

What is the maximum operating frequency of the STM32C011F6U6TR?

The STM32C011F6U6TR features an Arm Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable using the internal 48 MHz RC oscillator (±1% accuracy) or an external crystal up to 48 MHz. The CPU maintains full performance across the entire −40°C to 125°C temperature range without derating.

Does STM32C011F6U6TR support hardware encryption?

No, the STM32C011F6U6TR does not include dedicated hardware cryptographic accelerators (e.g., AES, SHA, PKA). However, it achieves PSA Level 3 and SESIP3 certification through secure boot enforcement, securable flash memory, MPU-based memory isolation, and tamper-resistant debug disable - providing foundational trust without crypto engines.

Can STM32C011F6U6TR operate from a single 3.3 V supply?

Yes, STM32C011F6U6TR operates within a 2.0–3.6 V supply range, making it fully compatible with standard 3.3 V LDOs or switching regulators. Its internal voltage regulator supports this range without external components, and all I/Os remain 5 V-tolerant even at 3.3 V VDD - simplifying interface to mixed-voltage systems.

What debug interface does STM32C011F6U6TR use?

The STM32C011F6U6TR uses Serial Wire Debug (SWD) with two dedicated pins: SWDIO and SWCLK. This two-wire interface supports full JTAG-equivalent functionality including breakpoints, memory inspection, and flash programming - with minimal PCB footprint and no requirement for a separate debug connector beyond standard SWD header pads.
