STMicroelectronics STM32C011J4M6

Overview

STM32C011J4M6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB flash, 6 KB SRAM, 2 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-designed for cost-sensitive industrial sensor nodes and smart metering interfaces.

For engineers reviewing the STM32C011J4M6 datasheet, STM32C011J4M6 pinout, STM32C011J4M6 application, or STM32C011J4M6 equivalent, key selection criteria include its SO8N 8-pin package, 48 MHz max CPU frequency, 125°C extended temperature rating, low-power Stop/Standby modes, and dual USART support with LIN/ISO7816 capability.

Technical Context

The STM32C011J4M6 implements a single-core Arm Cortex-M0+ with MPU, supporting TrustZone-like memory protection via securable flash area and hardware parity on SRAM. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and two internal oscillators (HSI48 ±1 %, LSI ±5 %) enabling precise timing without external crystals in many applications.

Peripheral interconnect uses a dedicated AHB/APB matrix with DMA request multiplexer (DMAMUX), allowing flexible routing of up to 3 DMA channels across timers, ADC, USARTs, and SPI. The device supports serial wire debug (SWD), SESIP3 and PSA Level 3 security certification, and boot from system memory or embedded flash.

FAQ

What is the maximum operating frequency of the STM32C011J4M6?

The STM32C011J4M6 runs its Arm Cortex-M0+ core at up to 48 MHz, achievable using either the internal 48 MHz RC oscillator (HSI48) 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.

Does the STM32C011J4M6 support hardware encryption or secure boot?

The STM32C011J4M6 includes a securable flash area and supports readout protection (RDP) levels that prevent unauthorized access to firmware. It is certified to SESIP3 and PSA Level 3 security standards, enabling secure boot implementation through protected flash sectors and hardware-assisted key management-not via dedicated crypto accelerators, but through trusted execution environment controls.

Can the STM32C011J4M6 operate without an external crystal?

Yes-the device can run entirely from its internal 48 MHz RC oscillator (HSI48), specified at ±1 % accuracy over voltage and temperature. The 32 kHz LSI RC oscillator (±5 %) supports basic RTC and low-power wake-up functions. External crystals are optional and used only when tighter timing precision (e.g., for USB or synchronous comms) is required.

How many ADC channels are accessible in the SO8N package?

In the SO8N package, four ADC input channels are physically accessible: PA0 (ADC1_IN0), PA1 (ADC1_IN1), PA2 (ADC1_IN2), and PA3 (ADC1_IN3). All are routed to the 12-bit ADC with 0.4 µs conversion time and hardware oversampling support, enabling simultaneous sampling of multiple analog sensors within the pin-count constraint.
