Product details
Overview
STM32C011J6M6 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 up to 48 MHz - deployed in industrial sensor nodes, smart metering interfaces, and low-power IoT edge controllers.
For engineers reviewing the STM32C011J6M6 datasheet, STM32C011J6M6 pinout, STM32C011J6M6 application, or STM32C011J6M6 equivalent, key selection factors include its SO8N 8-pin package, 5 V-tolerant I/Os, integrated RTC with alarm, Fast-mode Plus I²C (1 Mbit/s), and ISO7816/LIN-capable USART for secure peripheral interfacing.
Technical Context
The device integrates an Arm Cortex-M0+ core with MPU, supporting memory protection and securable flash area for firmware integrity. It features a multi-source clock system: 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 48 MHz RC oscillator.
Peripheral interconnect includes 3-channel DMA with flexible mapping, 8 timers (including advanced TIM1 for motor control), and communication interfaces with wake-up-from-Stop capability - enabling deterministic real-time response in battery-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, up to 48 MHz - enables real-time deterministic execution for control loops and protocol stacks. |
| Flash / RAM | 32 KB flash with securable area + 6 KB SRAM with hardware parity - supports certified firmware updates and data integrity in safety-aware applications. |
| ADC | 12-bit, 0.4 µs conversion time, up to 13 external channels - delivers high-speed analog sensing for voltage/current monitoring without external oversampling. |
| I/O Voltage Tolerance | 5 V-tolerant on all pins - simplifies interface with legacy 5 V peripherals without level-shifting circuitry. |
| Operating Voltage | 2.0–3.6 V - compatible with single-cell Li-ion, 3.3 V rails, and energy-harvesting power supplies. |
| Low-Power Modes | Sleep, Stop, Standby, Shutdown - achieves sub-µA shutdown current for multi-year battery life in always-on sensing nodes. |

Pinout & Package
STM32C011J6M6 uses the SO8N (8-pin small outline no-lead) package, measuring 4.9 × 6 mm, ECOPACK2-compliant, with exposed thermal pad for enhanced thermal dissipation in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply | 2.0–3.6 V input; powers core, SRAM, and most peripherals - requires local 100 nF decoupling. |
| VSS | Ground reference | Digital ground return path; must be connected to PCB ground plane with low-inductance routing. |
| NRST | Active-low reset input | Asynchronous reset trigger; accepts 5 V-tolerant logic; internal pull-up enables reset via external push-button or supervisor IC. |
| PA0 | General-purpose I/O / ADC1_IN0 | Configurable as digital I/O or analog input channel 0 - used for battery voltage monitoring or thermistor readout. |
| PA1 | General-purpose I/O / USART1_TX | Default TX line for primary UART; supports LIN bus physical layer when configured in LIN mode. |
| PA2 | General-purpose I/O / USART1_RX | Default RX line; includes auto-baud rate detection - enables plug-and-play serial configuration without pre-negotiated baud settings. |
| PA3 | General-purpose I/O / USART1_CK | USART clock output for synchronous SPI-like operation - allows master-slave clock synchronization in sensor daisy-chains. |
| PA4 | General-purpose I/O / SPI1_NSS | Chip select for primary SPI interface - active-low signal enabling multi-device SPI bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| SESIP3 & PSA Level 3 certification | Hardware-enforced security baseline for secure boot, cryptographic key isolation, and tamper-resistant firmware updates. |
| Calendar RTC with alarm | Real-time timestamping and scheduled wake-up from Stop mode - enables periodic sensor sampling without CPU intervention. |
| 5 V-tolerant I/Os | All 18 GPIOs withstand 5 V inputs - eliminates need for external level shifters when interfacing with industrial 5 V sensors or actuators. |
| Internal 48 MHz RC oscillator (±1%) | Factory-trimmed clock source - allows full-speed operation without external crystal, reducing BOM cost and board space. |
| Programmable brownout reset (BOR) | Three adjustable thresholds (2.1/2.4/2.7 V) - prevents erratic behavior during brownout conditions in unregulated power environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32C011F6U6 | UFQFPN20 package (20-pin, 3 × 3 mm); adds 2 extra GPIOs and 1 more USART. | Requires more PCB area but supports higher peripheral density - suitable for designs needing additional UART or SPI channels. | Select when pin count and interface expansion outweigh size constraints. |
| STM32G030F6P6 | Same SO8N package; 64 KB flash, no securable area or PSA certification; lacks ISO7816/LIN support. | Lower security assurance; suited for cost-sensitive consumer appliances where cryptographic enforcement is not required. | Choose only if security certification and smart-card protocol support are unnecessary. |
Compared with STM32C011F6U6, the J6M6 offers smaller footprint and lower assembly cost in SO8N, while STM32G030F6P6 trades security and protocol features for higher flash capacity - making the J6M6 optimal for space-constrained, certified industrial edge nodes.

FAQ
What is the maximum operating temperature range for STM32C011J6M6?
The STM32C011J6M6 is rated for operation from –40°C to 125°C ambient temperature, validated per ST's production data (DS13866 Rev 5). This extended range supports deployment in harsh industrial enclosures, automotive under-hood proximity, and outdoor utility metering without derating.
Does STM32C011J6M6 support hardware encryption accelerators?
No - the STM32C011J6M6 does not integrate dedicated AES or hash accelerators. Its security relies on SESIP3/PSA Level 3–certified secure boot, securable flash area, and memory protection unit (MPU) to enforce trusted execution and prevent unauthorized code access.
Can the internal 48 MHz RC oscillator replace an external crystal in production designs?
Yes - the factory-trimmed 48 MHz RC oscillator achieves ±1% accuracy over temperature and voltage, qualifying it for USB-free applications like UART, SPI, and PWM control. Crystal omission reduces BOM cost and improves reliability in vibration-prone environments.
How many USARTs support LIN physical layer compliance?
One USART (USART1) supports LIN 2.2 physical layer compliance via dedicated LIN mode, including slew-rate control, dominant timeout, and sync-break detection - verified in ST's AN5027 application note and DS13866 electrical characteristics tables.
