STMicroelectronics STM32G061C8U6

Overview

STM32G061C8U6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 64 KB Flash, 18 KB SRAM, dual 12-bit DACs, 12-bit ADC (0.4 µs conversion), and AES-128/256 hardware encryption. It operates from 1.7–3.6 V across –40°C to 105°C and integrates RTC, two USARTs (one with ISO7816/LIN/IrDA), two I²C (Fast-mode Plus), two SPI (32 Mbit/s), and low-power timers - deployed in smart metering, industrial sensor nodes, and secure IoT edge devices.

For engineers reviewing the STM32G061C8U6 datasheet, STM32G061C8U6 pinout, STM32G061C8U6 application, or STM32G061C8U6 equivalent, key selection criteria include its 48-pin UFQFPN package, 64 MHz max CPU frequency, dual DAC support for analog waveform generation, hardware RNG for cryptographic key derivation, and integrated VREFBUF for stable DAC reference - all critical for deterministic real-time control and secure firmware updates.

Technical Context

The STM32G061C8U6 implements an Arm Cortex-M0+ core with Memory Protection Unit (MPU) and supports TrustZone-like secure boot via securable flash area and readout protection levels. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and internal 16 MHz HSI with PLL for flexible timing precision.

Peripheral interconnect uses a multi-layer AHB/APB bus matrix enabling concurrent DMA transfers across ADC, DAC, timers, and communication interfaces. The 7-channel DMA controller supports flexible request mapping to peripherals including dual DACs, dual ADCs, and multiple UART/SPI instances - essential for sensor fusion and low-latency actuator control without CPU intervention.

FAQ

What is the maximum operating frequency of the STM32G061C8U6?

The STM32G061C8U6 features an Arm Cortex-M0+ core with a maximum CPU frequency of 64 MHz, achieved using the internal 16 MHz HSI oscillator with PLL multiplication or an external 4–48 MHz crystal. This frequency is fully supported across the full –40°C to 105°C temperature range and 1.7–3.6 V supply voltage, with timing validated per DS13513 Rev 4 Section 5.3.24.

Does the STM32G061C8U6 support hardware-accelerated cryptography?

Yes - it integrates a dedicated AES-128/256 hardware accelerator and a True Random Number Generator (TRNG) compliant with NIST SP800-90B. These blocks operate independently of the CPU, enabling secure key derivation, TLS record encryption, and firmware signature verification without software overhead or timing side-channel exposure.

How many analog-to-digital converter (ADC) channels does the STM32G061C8U6 provide?

The device includes a single 12-bit ADC with up to 16 external input channels and built-in features including hardware oversampling (up to 16× for 16-bit effective resolution), temperature sensor, VREFINT reference, and VBAT monitoring. All channels are accessible via dedicated pins (e.g., PA0–PA7, PB0–PB1) and support scan mode with DMA-triggered continuous acquisition.

What debug interface is supported by the STM32G061C8U6?

The STM32G061C8U6 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins (PA13/PA14), compliant with ARM CoreSight standards. It enables full JTAG/SWD functionality including halt/resume, memory inspection, register access, and real-time trace via ITM - no external debug probe required beyond standard ST-LINK v2/v3 or CMSIS-DAP adapters.
