STMicroelectronics STM32G061C6T6

Overview

STM32G061C6T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 32 KB Flash, 18 KB SRAM, dual USARTs (one supporting LIN/ISO7816), 12-bit ADC (0.4 µs conversion), and dual 12-bit DACs - deployed in smart sensor nodes, industrial control panels, and battery-powered metering systems.

For engineers reviewing the STM32G061C6T6 datasheet, STM32G061C6T6 pinout, STM32G061C6T6 application, or STM32G061C6T6 equivalent, key selection criteria include operating voltage range (1.7–3.6 V), low-power Stop/Standby modes, AES-128 encryption support, and 5 V-tolerant GPIOs for mixed-voltage interfacing.

Technical Context

The STM32G061C6T6 integrates an Arm Cortex-M0+ core running up to 64 MHz with MPU, hardware RNG, and AES accelerator - enabling secure firmware execution and cryptographic operations without software overhead. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and internal 16 MHz HSI with PLL for flexible timing control.

Peripheral interconnect supports concurrent operation: 7-channel DMA handles ADC/DAC/SPI transfers; two I²C interfaces (one Fast-mode Plus at 1 Mbit/s) and two SPIs (32 Mbit/s) enable multi-sensor communication; RTC with alarm and periodic wakeup enables time-triggered low-power scheduling.

FAQ

What is the maximum operating frequency and voltage range of the STM32G061C6T6?

The STM32G061C6T6 operates at up to 64 MHz using its internal 16 MHz HSI with PLL, or external crystal sources. Its supply voltage range is strictly 1.7 V to 3.6 V - operation outside this range risks functional failure or permanent damage. The device includes programmable Brownout Reset (BOR) and Voltage Detector (PVD) to enforce safe operation boundaries.

Does the STM32G061C6T6 support hardware debugging, and what interface is used?

Yes, the STM32G061C6T6 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. This 2-wire interface enables full debug functionality - including breakpoints, register inspection, and flash programming - without requiring JTAG pins. SWD is compatible with ST-LINK/V2-1 and other CMSIS-DAP compliant debuggers.

How many analog inputs does the integrated ADC support, and what is its resolution?

The integrated 12-bit ADC supports up to 16 external channels (via PA0–PA7, PB0–PB1, PC0–PC5, etc.) plus internal channels (temperature sensor, VREFINT, VBAT). It achieves 0.4 µs conversion time and supports hardware oversampling up to 16× for effective 16-bit resolution - verified in DS13513 Rev 4, Table 59.

Is the STM32G061C6T6 qualified for industrial temperature operation?

Yes, the STM32G061C6T6 is rated for industrial temperature range: –40°C to +85°C (ambient), with extended variants supporting up to +105°C and +125°C. This rating is confirmed in the "Operating conditions" section (Section 5.3.1) of DS13513 Rev 4 and applies to all package variants including the UFQFPN48.
