STMicroelectronics STM32G030C6T6

Overview

STM32G030C6T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 32 KB Flash, 8 KB SRAM, operating at up to 64 MHz, supporting 2.0–3.6 V supply, and featuring two USARTs, one 12-bit ADC (0.4 µs conversion), eight timers including SysTick and watchdogs, and RTC with wakeup from Stop/Standby - deployed in industrial sensor nodes and smart metering front-ends.

For engineers reviewing the STM32G030C6T6 datasheet, STM32G030C6T6 pinout, STM32G030C6T6 application, or STM32G030C6T6 equivalent, key selection criteria include Flash/RAM size, 5 V-tolerant I/O count (up to 38), low-power mode timing (Stop 0 wakeup ≤ 4.5 µs), ADC resolution and oversampling capability, and SWD debug interface compatibility.

Technical Context

The device integrates an Arm Cortex-M0+ core with MPU, a 12-bit ADC with hardware oversampling up to 16-bit effective resolution, and dual clock domains: high-speed (HSI16/PLL up to 64 MHz) and low-speed (LSE/LSI for RTC and watchdogs). It supports boot from system memory, main Flash, or SRAM via BOOT pins.

Peripherals are interconnected via AHB/APB buses with DMA channel mapping flexibility; GPIOs support interrupt on all pins, multiple alternate functions (USART/I2C/SPI), and 5 V tolerance on selected pins. Power management includes three low-power modes (Sleep, Stop, Standby) with VBAT backup for RTC and registers.

Key Specifications

Pinout & Package

LQFP48 package (7 × 7 mm, 0.5 mm pitch), ECOPACK2-compliant, with exposed thermal pad for enhanced heat dissipation in compact industrial PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with STM32G030C6T6, the STM32G031K8T6 offers greater Flash and serial interface count in a smaller LQFP32 package but sacrifices I/O count and thermal performance; the LPC804 lacks RTC/Stop wakeup entirely, limiting its utility in energy-harvesting or time-aware systems.

FAQ

What is the maximum operating frequency and voltage range of the STM32G030C6T6?

The STM32G030C6T6 operates at up to 64 MHz using its internal HSI16 oscillator with PLL, and supports a supply voltage range of 2.0 V to 3.6 V. Its absolute maximum ratings specify VDD = 4.0 V, and it maintains full functionality across –40°C to +85°C ambient temperature per datasheet DS12991 Rev 6.

Does the STM32G030C6T6 support hardware encryption or secure boot features?

No, the STM32G030C6T6 does not include hardware cryptographic accelerators (AES, PKA) or secure boot ROM. It supports readout protection (RDP) Level 1 and write protection (WRP) for Flash, but lacks true secure boot with signature verification - unlike higher-tier G0 models such as STM32G071 or G0B1.

Can the STM32G030C6T6 drive 5 V logic directly without level shifters?

Yes - 38 GPIOs include multiple 5 V-tolerant pins (e.g., PA0–PA7, PB0–PB1, PC13–PC15, PD0–PD2), which accept input voltages up to 5.5 V while powered from 2.0–3.6 V. However, output voltage remains VDD-referenced (~3.3 V), so driving 5 V inputs requires checking receiver VIH thresholds.

What debug interfaces are supported, and is SWD the only option?

The STM32G030C6T6 supports Serial Wire Debug (SWD) only - no JTAG support. SWD uses two pins (SWDIO and SWCLK) and is fully compatible with ST-LINK v2/v3, SEGGER J-Link, and other CMSIS-DAP compliant debuggers. No external pull-ups are required on these pins per the reference design.
