STMicroelectronics STM32C011F6P6

Overview

STM32C011F6P6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB flash, 6 KB SRAM, dual USARTs, 12-bit ADC (0.4 µs conversion), and operation from 2.0–3.6 V. It integrates a 48 MHz internal RC oscillator (±1 %), programmable brownout reset, and 18 fast 5 V-tolerant I/Os-used in industrial sensor nodes requiring low-power serial telemetry and local control.

For engineers reviewing the STM32C011F6P6 datasheet, STM32C011F6P6 pinout, STM32C011F6P6 application, or STM32C011F6P6 equivalent, key selection criteria include its TSSOP20 package, 48 MHz max CPU frequency, 125°C extended temperature rating, integrated CRC unit, and support for ISO7816/LIN/IrDA on USART1.

Technical Context

The device implements an Arm Cortex-M0+ core with MPU, supporting privileged/unprivileged execution modes and memory protection for secure firmware partitioning. Its clock system combines four independent sources: 4–48 MHz HSE, 32 kHz LSE with calibration, 48 MHz HSI48 (±1 %), and 32 kHz LSI (±5 %), enabling precise timing control across low-power and high-performance states.

Peripherals are interconnected via a multi-layer AHB/APB bus matrix, allowing concurrent DMA transfers and peripheral access without arbitration stalls. The 3-channel DMA controller supports flexible request mapping to 12 peripherals-including ADC, USARTs, SPI, and timers-with configurable data width and transfer triggers.

FAQ

What is the maximum operating frequency of the STM32C011F6P6?

The STM32C011F6P6 features an Arm Cortex-M0+ core rated for up to 48 MHz operation using the internal 48 MHz HSI48 oscillator (±1 % accuracy) or an external crystal. This frequency is fully supported across the full −40°C to 125°C temperature range and 2.0–3.6 V supply voltage, with no derating required in datasheet-specified conditions.

Does the STM32C011F6P6 support hardware encryption acceleration?

No, the STM32C011F6P6 does not include dedicated hardware crypto accelerators (e.g., AES, SHA, PKA). Security relies on its SESIP3 and PSA Level 3 certified secure boot, securable flash area, readout protection, and memory protection unit (MPU) to enforce trusted execution environments and isolate sensitive code/data.

Can the STM32C011F6P6 drive a 32.768 kHz crystal for RTC operation?

Yes, the STM32C011F6P6 includes a dedicated low-speed external (LSE) oscillator circuit on PC14/PC15 pins, supporting 32.768 kHz crystals with automatic calibration against the internal LSI. The LSE startup time is 1.5 s (max), and the RTC maintains ±1 ppm accuracy over temperature when calibrated per AN5089.

What debug interface is supported, and are external pull-ups required?

The STM32C011F6P6 supports Serial Wire Debug (SWD) via PA13 (SWDIO) and PA14 (SWCLK). No external pull-up resistors are needed-the SWDIO pin has an internal weak pull-up, and SWCLK is driven actively by the debugger. Standard 10-pin SWD connectors are compatible without additional passive components.
