STMicroelectronics STM32C011J6M6TR

Overview

STM32C011J6M6TR 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 operating voltage range of 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-designed for cost-sensitive industrial sensor nodes and smart metering front-ends.

For engineers reviewing the STM32C011J6M6TR datasheet, STM32C011J6M6TR pinout, STM32C011J6M6TR application, or STM32C011J6M6TR equivalent, key selection criteria include its SO8N 8-pin package footprint, 48 MHz max CPU frequency, 125°C extended temperature rating, ISO7816/LIN-capable USART, and PSA Level 3 security certification for secure firmware deployment.

Technical Context

This MCU implements a single-core Arm Cortex-M0+ with Memory Protection Unit (MPU) and supports boot from system memory, main flash, or SRAM. Its clock tree includes dual crystal oscillators (4–48 MHz HSE and 32 kHz LSE), plus two precision RC sources (HSI48 ±1 %, LSI ±5 %), enabling flexible low-power timing architectures.

The peripheral interconnect uses a multi-layer AHB/APB bus matrix supporting concurrent DMA transfers across UART, SPI, I²C, timers, and ADC. All 18 GPIOs support external interrupt vectors and remappable alternate functions-including SPI/I²S multiplexing on USART pins and Fast-mode Plus I²C (1 Mbit/s) with SMBus/PMBus™ compatibility.

FAQ

What is the maximum operating frequency of the STM32C011J6M6TR?

The STM32C011J6M6TR runs at a maximum CPU frequency of 48 MHz using its internal HSI48 oscillator (±1 % accuracy) or an external crystal up to 48 MHz. 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 production conditions.

Does STM32C011J6M6TR support hardware encryption or secure boot?

Yes-it includes a securable flash area and is certified to PSA Level 3 and SESIP3 standards. Secure boot is enforced by hardware, preventing unauthorized code execution. The securable area can be locked to protect bootloader integrity and cryptographic keys, meeting requirements for IEC 62443-3-3 and EN 1434-3 compliance in utility metering.

Can STM32C011J6M6TR operate from a single 3.3 V supply without external regulators?

Yes-the device integrates an internal voltage regulator that accepts 2.0–3.6 V directly. When powered from a clean 3.3 V source, no external regulator is needed; however, separate VDDA and VSSA connections with dedicated analog filtering are required for ADC accuracy below ±2 LSB across temperature.

Is the SO8N package of STM32C011J6M6TR compatible with standard 8-pin SOIC footprints?

No-the SO8N (Small Outline Narrow) has 1.27 mm pitch and 4.9 × 6 mm body, differing from standard SOIC-8 (3.9 × 4.9 mm, 1.27 mm pitch but wider lead span). PCB land patterns must follow ST's AN5053 guidelines; using generic SOIC-8 footprints risks solder bridging and mechanical stress on leads.
