STM32G030C8T6 Complete Guide: 64KB Flash ARM Cortex-M0+ MCU Specs, Pinout, Alternatives, and Design Tips

The STM32G030C8T6 is a 32-bit ARM Cortex-M0+ microcontroller from STMicroelectronics that combines a 64 MHz core, 64 KB of Flash memory, and 8 KB of SRAM in a 48-pin LQFP (7x7 mm) surface-mount package. It operates from a 2.0V to 3.6V supply, integrates a 12-bit ADC with 19 channels, advanced-control timers, I2C, SPI, USART, and LPUART interfaces, plus a 5-channel DMA and RTC. The device carries an active lifecycle status and is RoHS compliant. It is in stock at XAIPART with more than 99,000 units available, MOQ 1, priced from $2.15 for a single unit down to $1.47 at 1,000 units as of 2026-09-12, making it a strong choice for industrial control, IoT nodes, home automation, consumer electronics, battery-powered equipment, and motor control designs that need mainstream MCU performance at a cost-optimized price point.

What Are the Quick Answers Buyers and Engineers Need About the STM32G030C8T6?

The most common questions from purchasing teams and design engineers center on availability, price, drop-in replacements, and whether the part fits the target application. The verified facts: stock on the XAIPART STM32G030C8T6 product page stands at 99,999 units with an MOQ of 1, the lifecycle status is active, and tiered pricing steps from $2.15 (qty 1) to $1.47 (qty 1,000+) as of 2026-09-12. For replacements, the STM32G030C8T6TR is the same die in tape-and-reel packaging; the STM32G031C8T6 is pin-compatible with additional analog features such as a 12-bit DAC. Full FAQ coverage appears in the structured FAQ block accompanying this article, and every answer is anchored to the verified specification table below.

How Do You Select and Design In the STM32G030C8T6?

Selecting the STM32G030C8T6 starts with matching its verified resources to your firmware budget. The 64 KB Flash accommodates mid-range applications including industrial control firmware, IoT protocol handling, and consumer device logic, while the 8 KB SRAM suits control loops and moderate buffering. If your application requires a DAC or richer analog peripherals, move up to the STM32G031C8T6; if those features are unnecessary, the cost-optimized STM32G030C8T6 is the right fit.

Power supply design: the device accepts 2.0V to 3.6V, allowing direct connection to a lithium-ion battery. Decouple all power supply pins with 100 nF capacitors placed close to the VDD pins. The LQFP-48 provides separate VDDA and VSSA analog supply pins (pins 46 and 48) plus a VREF+ ADC reference pin (pin 47); treat the analog domain carefully for best 12-bit ADC accuracy.

Debug and programming: the SWD interface is available on PA13 (SWDIO, pin 34) and PA14 (SWCLK, pin 35). The device is supported by STM32CubeMX, STM32CubeIDE, the STM32CubeG0 firmware library, Keil MDK, IAR EWARM, and GCC-based toolchains, giving teams a complete development environment from configuration to deployment.

Peripheral allocation: pins PA0 through PA7 multiplex ADC inputs 0 through 7 with Timer 2 channels and SPI1 signals; PB10/PB11 carry I2C2 and USART3; PA9/PA10 provide USART1; PB6/PB7 provide I2C1 with USART1 alternates. For motor control, advanced-control timer outputs appear on PB14 (TIM1_CH2N) and PB15 (TIM1_CH3N) with PA8 to PA10 offering TIM1_CH1 to TIM1_CH3, enabling complementary PWM with dead-time insertion for H-bridge or three-phase inverter drives. Use the 5-channel DMA to offload ADC sampling and UART transfers from the 64 MHz Cortex-M0+ core. For battery-powered designs, schedule work with the RTC and place the device in Stop or Standby between measurements; in Standby with the RTC off, the device draws as little as 0.3 uA typical.

What Are the Alternatives and How Does the STM32G030C8T6 Compare?

Verified alternatives in the database are the STM32G030C8T6TR (same die, tape-and-reel packaging variant, suited to automated high-volume assembly) and the NXP LPC824M201JHI33 (similar Cortex-M0+ class, but different package and pinout, so it is not drop-in). The STM32G031C8T6 is pin-compatible and offers a superset of features including a 12-bit DAC, at a slightly higher cost. Full spec data for the alternatives is not provided in this dataset, so the comparison table lists the STM32G030C8T6 against the functional relationship of each alternative.

Recommendation: for new designs at XAIPART pricing, start with the STM32G030C8T6. If your BOM requires reel packaging, order the STM32G030C8T6TR. If a DAC or advanced analog features become necessary mid-project, the STM32G031C8T6 is a pin-compatible upgrade path that protects your PCB investment.

What Is the Market Position, Lifecycle, and Supply Situation for the STM32G030C8T6?

The STM32G030C8T6 carries an active lifecycle status from STMicroelectronics, meaning it is in current production and safe to design into new products. On the supply side, XAIPART lists 99,999 units in stock with MOQ 1 as of 2026-09-12, eliminating near-term sourcing risk for prototypes and mid-volume production. Pricing is transparent and tiered: $2.15 at qty 1, $1.93 at qty 10, $1.72 at qty 100, $1.55 at qty 500, and $1.47 at qty 1,000 as of 2026-09-12. [DATA_NEEDED: manufacturer lifecycle milestone dates, projected end-of-life timeline, and broader market demand forecast data]. For high-volume commitments, confirm allocation and lead times with your distributor, since lead time typically ranges from 2 to 4 weeks depending on order quantity.

What Trends Should Buyers Watch, Anchored to Verified Specs?

Three trends matter for buyers of this part. First, cost-optimized mainstream MCUs are consolidating around Cortex-M0+ architectures; the STM32G030C8T6's 64 MHz core, 64 KB Flash, and 8 KB SRAM place it squarely in the mainstream segment, and the pin-compatible STM32G031C8T6 upgrade path means your PCB footprint remains valid as requirements grow. Second, battery-powered and always-on IoT designs increasingly depend on microamp-level standby consumption; this device's Sleep, Stop, and Standby modes, integrated RTC, and 2.0V to 3.6V direct-battery operation align with that direction, with 0.3 uA typical in Standby with the RTC off. Third, packaging and compliance: the LQFP-48 (7x7 mm) surface-mount package, RoHS compliance, and tape-and-reel availability (STM32G030C8T6TR) support automated assembly and EU market requirements. Watch tiered pricing as volumes scale — moving from 100 units ($1.72) to 1,000 units ($1.47) yields roughly 15% unit savings as of 2026-09-12 — and monitor stock depth at XAIPART, where current inventory exceeds 99,000 units.
