Key Features
- Arm Cortex-M0+ core at 48 MHz delivers up to 49 DMIPS for cost-sensitive embedded control
- 32 KB Flash and 12 KB RAM in a single chip minimize BOM cost for space-constrained designs
- 2x USART plus SPI and I2C peripherals cover most serial communication needs without external bridges
- Integrated 12-bit ADC with multiple channels enables direct analog sensor acquisition
- Tape-and-reel (TR) packaging with LQFP-32 footprint supports automated high-volume SMT assembly
Applications
The STM32C031K6T6TR targets cost-sensitive consumer and industrial applications such as smart home sensors, motor-speed controllers, and simple user-interface panels that require a 32-bit processor without the overhead of a full Cortex-M4. Its 48 MHz Cortex-M0+ core and 32 KB Flash are sufficient for Bluetooth Low Energy companion firmware, UART-based protocol bridges, and capacitive-touch keypad controllers. The LQFP-32 package keeps PCB area under 7 mm x 7 mm, making it attractive for wearable accessories and compact IoT edge nodes.

Frequently Asked Questions
How much Flash and RAM does the STM32C031K6T6TR include, and is that sufficient for a FreeRTOS application?
The STM32C031K6T6TR provides 32 KB of Flash and 12 KB of SRAM. A minimal FreeRTOS kernel with 4 tasks typically consumes about 8 KB of Flash and 4 KB of RAM, leaving roughly 24 KB Flash and 8 KB RAM for application code — enough for simple sensor-acquisition or protocol-bridge firmware running at 48 MHz.
Which serial interfaces does the STM32C031K6T6TR offer for connecting external sensors or displays?
The MCU integrates 2x USART, 1x SPI, and 1x I2C, enabling simultaneous connections to a UART GPS module, an SPI display, and an I2C temperature sensor without any external logic. All interfaces operate at 3.3 V I/O voltage and support DMA transfers to reduce CPU load at communication speeds up to several megabits per second.
For a low-power IoT sensor node, what sleep modes does the STM32C031K6T6TR support?
The STM32C031K6T6TR supports Sleep, Stop, and Standby low-power modes. In Standby mode the MCU can reduce current consumption to below 1 µA while retaining the RTC oscillator, enabling periodic wake-up intervals from 1 second to several hours on a small 100 mAh coin cell without external power management ICs.
When is STM32C031K6T6TR a better fit than STM32G031 for a new design?
The STM32C031K6T6TR belongs to the newer STM32C0 series optimized for the lowest price point at 32 KB Flash and 48 MHz, whereas the STM32G031 targets slightly higher performance with a 64 MHz Cortex-M0+ and additional peripherals like LPUART and DAC. Choose STM32C031K6T6TR when BOM cost is the primary constraint and the application does not require analog output or low-power UART wakeup below 3.3 V.
