Product details
Overview
STM32G061C6U6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in UFQFPN28 package, operating up to 64 MHz with 32 KB Flash, 18 KB SRAM, and integrated AES-128/256 encryption. It features two 12-bit DACs, a 12-bit 0.4 µs ADC (16-channel), dual USARTs with LIN/IrDA support, and RTC with alarm-used in secure industrial sensor nodes requiring low-power operation and cryptographic integrity.
For engineers reviewing the STM32G061C6U6 datasheet, STM32G061C6U6 pinout, STM32G061C6U6 application, or STM32G061C6U6 equivalent, key selection factors include its 28-pin UFQFPN footprint, 1.7–3.6 V supply range, -40°C to 85°C temperature grade, dual DAC support for analog actuation, and hardware RNG/AES for firmware authentication in resource-constrained edge devices.
Technical Context
The STM32G061C6U6 implements an Arm Cortex-M0+ core with Memory Protection Unit (MPU) and supports multiple clock sources: 4–48 MHz HSE crystal, 32 kHz LSE with calibration, 16 MHz HSI with PLL, and 32 kHz LSI RC oscillator. Its interrupt architecture includes NVIC with 32 external lines and EXTI for wake-up from Stop/Standby modes.
Peripheral interconnect uses a hierarchical AHB/APB bus matrix supporting concurrent DMA transfers across 7-channel controller with flexible mapping. Analog subsystem integrates temperature sensor, VREFINT, VBAT monitoring, and rail-to-rail comparators with programmable hysteresis-enabling self-calibrating sensor front-ends without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G071CBT6 | 64 KB Flash, 36 KB SRAM, same peripheral set, LQFP48 package | Requires larger PCB footprint and lacks UFQFPN28's thermal performance for sealed enclosures | Select when extended code size or additional GPIOs justify larger package and higher BOM cost. |
| STM32G031F8P6 | 16 KB Flash, 8 KB SRAM, no DAC, single USART, no AES/RNG | Lower security and analog capability - suitable only for basic control tasks without encryption or analog output | Select only for cost-sensitive non-secure applications where cryptographic and dual-DAC functions are unnecessary. |
Compared with STM32G071CBT6, the STM32G061C6U6 trades Flash/SRAM capacity for compactness and thermal efficiency; versus STM32G031F8P6, it adds hardware security and analog precision at modest cost premium - making it optimal for secure, space-constrained edge nodes.

FAQ
What is the maximum operating frequency and supported voltage range for STM32G061C6U6?
The STM32G061C6U6 operates at up to 64 MHz and supports a supply voltage range of 1.7 V to 3.6 V. This range accommodates both single-cell Li-ion (3.0–3.6 V) and coin-cell (1.8–3.0 V) power sources. The core voltage is regulated internally, and the device maintains full functionality across the entire voltage range without performance throttling.
Does STM32G061C6U6 support hardware-based secure boot and firmware authentication?
Yes. STM32G061C6U6 includes readout protection (RDP) levels, securable Flash area, and hardware AES-128/256 with True RNG - enabling secure boot chain verification and authenticated firmware updates. Factory-programmed 96-bit unique ID allows binding cryptographic keys to individual devices, satisfying basic Common Criteria requirements for firmware integrity.
How many analog-to-digital converter (ADC) channels does STM32G061C6U6 support, and what is its conversion speed?
The STM32G061C6U6 integrates a single 12-bit ADC supporting up to 16 external input channels and 4 internal channels (temperature sensor, VREFINT, VBAT, and DAC outputs). Its maximum conversion rate is 2.5 MSPS (0.4 µs per sample), with hardware oversampling enabling up to 16-bit effective resolution - sufficient for precision sensor signal conditioning without external ADCs.
What debug interface is supported, and is SWD compatible with standard JTAG probes?
STM32G061C6U6 supports Serial Wire Debug (SWD) only - not full JTAG. It is fully compatible with standard ARM SWD debug probes (e.g., ST-LINK v2/v3, Segger J-Link) using the 4-pin SWDIO/SWCLK/NRST/GND interface. SWD offers reduced pin count and faster programming versus JTAG, and all official ST development tools natively support this interface.
