Product details
Overview
STM32C031F6P7 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 32 KB flash, 12 KB SRAM, dual USARTs (one with LIN/ISO7816), 12-bit ADC (19-channel), and 45 5 V-tolerant I/Os - deployed in industrial sensor nodes, smart metering interfaces, and low-power motor control subsystems.
For engineers reviewing the STM32C031F6P7 datasheet, STM32C031F6P7 pinout, STM32C031F6P7 application, or STM32C031F6P7 equivalent, key selection criteria include operating voltage range (2.0–3.6 V), -40°C to 125°C extended temperature grade, integrated CRC unit, hardware parity on SRAM, and SWD debug support for production firmware validation.
Technical Context
This MCU integrates an Arm Cortex-M0+ core with MPU, supporting up to 48 MHz operation and featuring tightly coupled peripherals including three DMA channels, calendar RTC with alarm, and Fast-mode Plus I²C (1 Mbit/s) with SMBus/PMBus compatibility and Stop-mode wake-up capability.
Its clock system combines four oscillators: 4–48 MHz HSE, 32 kHz LSE with calibration, 48 MHz HSI (±1%), and 32 kHz LSI (±5%); power management includes programmable BOR, POR/PDR, and four low-power modes (Sleep, Stop, Standby, Shutdown) with sub-μA shutdown current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, 48 MHz max - enables real-time deterministic control in resource-constrained embedded systems. |
| Memory | 32 KB flash (with readout protection), 12 KB SRAM (hardware parity) - supports secure firmware storage and error-detecting data buffers. |
| ADC | 12-bit, 0.4 µs conversion, up to 19 external channels - delivers high-resolution analog sensing for battery monitoring or environmental sensing. |
| Timers | 8 timers: 1 advanced-control (TIM1), 4 general-purpose (TIM3/14/16/17), 2 watchdogs (IWDG/WWDG), SysTick - enables motor commutation, PWM generation, and system supervision. |
| Communication | 2× USART (1 with LIN/ISO7816/IrDA), 1× I²C (Fast-mode Plus), 1× SPI (24 Mbit/s) - supports wired industrial protocols and legacy interface bridging. |
| I/O | Up to 45 fast I/Os, all 5 V-tolerant and interrupt-capable - simplifies level-shifting in mixed-voltage designs and enables direct connection to industrial sensors/actuators. |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive modules, industrial PLC I/O cards, and outdoor metering enclosures. |
Pinout & Package
TSSOP20 package (6.4 × 4.4 mm, 0.65 mm pitch), RoHS-compliant and ECOPACK2 certified. Pin count and layout optimized for compact board space and cost-sensitive applications requiring moderate peripheral integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Main 2.0–3.6 V digital supply rail; decoupling required per datasheet layout guidelines. |
| VSS | Ground | Digital ground reference; separate analog ground not required due to internal routing. |
| NRST | Reset input | Active-low reset with internal pull-up; supports external reset button or supervisor IC assertion. |
| PA0–PA9 | General-purpose I/O | Configurable as GPIO, ADC inputs (PA0–PA7), USART TX/RX (PA2/PA3), or timer channels - enables flexible signal routing. |
| PA13/PA14 | SWD debug | Serial Wire Debug (SWDIO/SWCLK) pins - provides non-intrusive programming and real-time debugging without dedicated JTAG header. |
| BOOT0 | Boot mode select | High at reset forces system memory boot (for DFU); tied low for normal flash execution - critical for field firmware recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CRC unit | Accelerates firmware integrity checks and communication frame validation without CPU overhead. |
| SRAM parity checking | Detects single-bit errors in RAM during runtime - essential for safety-critical sensor data buffering. |
| 5 V-tolerant I/Os | Eliminates external level shifters when interfacing with legacy 5 V logic or industrial sensors. |
| Low-power Stop mode | Typical 0.32 µA consumption with RTC running - extends battery life in wireless sensor endpoints. |
| Calibrated 32 kHz LSE | Enables accurate RTC timekeeping without external crystal trimming components - reduces BOM count. |

FAQ
What is the maximum operating frequency of the STM32C031F6P7?
The STM32C031F6P7 operates at up to 48 MHz using its internal 48 MHz HSI oscillator (±1%) or external crystal. This frequency is fully supported across the full -40°C to +125°C temperature range and 2.0–3.6 V supply, with all peripherals functional at maximum speed per DS13867 Rev 4 Section 5.3.17.
Does the STM32C031F6P7 support hardware encryption?
No - the STM32C031F6P7 does not include hardware AES or PKA accelerators. It features a CRC calculation unit for data integrity but lacks cryptographic co-processors. For encrypted firmware or secure communication, designers must implement software-based algorithms or select the STM32G031F6P7, which integrates AES-128.
What debug interface does the STM32C031F6P7 provide?
The STM32C031F6P7 supports Serial Wire Debug (SWD) via PA13 (SWDIO) and PA14 (SWCLK). It does not support JTAG. SWD enables full programming, breakpoint setting, and real-time variable inspection using standard ST-LINK/V2-1 or compatible debug probes, as confirmed in Section 3.20.1 of DS13867 Rev 4.
Is the STM32C031F6P7 pin-compatible with other STM32C0 packages?
Yes - the TSSOP20 package (F6P7 suffix) shares identical pinout with STM32C011F4P6 and STM32C031F4P6. However, it is not pin-compatible with UFQFPN28 or LQFP32 variants of the same family; those use different pin assignments and require PCB redesign for migration.
