STMicroelectronics STM32G061K6T6

Overview

STM32G061K6T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB Flash, 18 KB SRAM, operating at up to 64 MHz, supporting 1.7–3.6 V supply and -40°C to 85°C temperature range. It integrates dual 12-bit DACs, 12-bit ADC (0.4 µs conversion), AES-128/256 encryption, RNG, RTC with alarm, and two USARTs - deployed in smart sensor nodes requiring secure local processing and low-power wireless telemetry.

For engineers reviewing the STM32G061K6T6 datasheet, STM32G061K6T6 pinout, STM32G061K6T6 application, or STM32G061K6T6 equivalent, key selection criteria include its 28-pin UFQFPN package, 64 MHz CPU clock with hardware parity on 16 KB SRAM, dual DAC support for analog actuation, AES acceleration for firmware integrity, and LPUART wakeup capability in Stop mode.

Technical Context

The STM32G061K6T6 implements a single-core Arm Cortex-M0+ with Memory Protection Unit (MPU), enabling secure partitioning of code and data spaces. Its clock system combines internal 16 MHz RC (with PLL) and external 4–48 MHz crystal options, plus a calibrated 32 kHz LSE for RTC accuracy within ±20 ppm over temperature.

Peripheral interconnect uses a hierarchical AHB/APB bus matrix supporting concurrent DMA transfers across UART, SPI, I2C, and ADC. The 7-channel DMA controller features flexible request mapping and supports memory-to-peripheral, peripheral-to-memory, and memory-to-memory transfers without CPU intervention.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32G061K6T6 operates at up to 64 MHz using its internal 16 MHz RC oscillator with PLL, or external crystal sources. It supports a supply voltage range of 1.7 V to 3.6 V across its full industrial temperature range (–40°C to 85°C), with guaranteed performance and timing specifications validated per DS13513 Rev 4.

Does this MCU support hardware encryption and secure boot?

Yes - it integrates a dedicated AES-128/256 hardware accelerator and True Random Number Generator (RNG), both accessible via STM32Cube HAL libraries. While it does not include ROM-based secure boot, its securable flash area, readout protection (RDP), and option bytes enable customer-implemented secure boot flows with tamper-resistant key storage.

How many analog-to-digital converter channels are available and what is their resolution?

The device features a single 12-bit ADC with up to 16 external input channels (PA0–PA7, PB0–PB1, PF0–PF1), plus internal channels for temperature sensor and VREFINT. Conversion time is 0.4 µs at maximum speed, and hardware oversampling supports effective resolution up to 16 bits for noise-sensitive measurements.

What debug interface is supported and are SWD pins shared with other functions?

It supports Serial Wire Debug (SWD) via dedicated SWCLK and SWDIO pins (PA14 and PA13), which are not multiplexed with any other peripheral functions. These pins remain available for debug throughout all operational modes except when explicitly remapped via SYSCFG registers - a rare configuration requiring deliberate firmware action.
