STMicroelectronics STM32G061C8T6

Overview

STM32G061C8T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 64 KB Flash, 18 KB SRAM, dual USARTs (one with ISO7816/LIN/IrDA), two 12-bit DACs, and hardware AES-128/256 encryption. It operates from 1.7–3.6 V across –40°C to 125°C and integrates calendar RTC, 14 timers (including two 128 MHz-capable), and a 12-bit 0.4 µs ADC with up to 16 external channels - deployed in industrial sensor nodes requiring secure, low-power edge processing.

For engineers reviewing the STM32G061C8T6 datasheet, STM32G061C8T6 pinout, STM32G061C8T6 application, or STM32G061C8T6 equivalent, key selection criteria include its 48-pin UFQFPN package, 64 MHz max CPU frequency, dual DAC support for analog actuation, AES acceleration for firmware integrity, and I/O tolerance enabling direct interfacing with legacy 5 V peripherals.

Technical Context

The STM32G061C8T6 implements a single-core Arm Cortex-M0+ with Memory Protection Unit (MPU), supporting TrustZone-like isolation via securable flash area and readout protection levels. Its clock system combines four oscillators: 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI with PLL, and 32 kHz LSI - enabling precise RTC operation and dynamic voltage scaling across low-power modes.

Peripheral interconnect uses a hierarchical AHB/APB bus matrix with DMA request multiplexer (DMAMUX) routing 7-channel DMA to 39 possible requests. Analog subsystem includes rail-to-rail comparators with programmable hysteresis, temperature sensor, VREFINT, and VBAT monitoring - all accessible without CPU intervention via autonomous trigger paths.

FAQ

What is the maximum operating frequency and core type of the STM32G061C8T6?

The STM32G061C8T6 features an Arm Cortex-M0+ core rated for up to 64 MHz operation. This frequency is achieved using the internal 16 MHz HSI oscillator with PLL multiplication or an external crystal up to 48 MHz. The core includes a Memory Protection Unit (MPU) and supports Thumb-2 instruction set for efficient code density and deterministic interrupt response.

Does the STM32G061C8T6 support hardware-based cryptographic acceleration?

Yes, it integrates a dedicated AES-128 and AES-256 hardware accelerator plus a True Random Number Generator (RNG). These blocks operate independently of the CPU, enabling secure boot validation, encrypted firmware updates, and TLS session key derivation without impacting real-time task execution or increasing software footprint.

How many analog-to-digital converter (ADC) channels does the STM32G061C8T6 provide, and what is its conversion speed?

The device includes a single 12-bit ADC with up to 16 external input channels and a 0.4 µs conversion time (2.5 MSPS). It supports hardware oversampling up to 16× for effective 16-bit resolution, and integrates internal references (VREFINT), temperature sensor, and VBAT monitoring - all usable without CPU polling via DMA-triggered sequences.

What package type and pin count does the STM32G061C8T6 use, and is it pin-compatible with other STM32G0 variants?

STM32G061C8T6 uses a 48-pin UFQFPN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. It shares identical pinout with STM32G071CBT6 and STM32G081CBT6 in the same package, enabling drop-in upgrades for added RAM or USB functionality - provided PCB layout accommodates the thermal pad soldering requirements.
