STMicroelectronics STM32G030C8T6

Overview

STM32G030C8T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 64 KB Flash, 8 KB SRAM, two USARTs, 12-bit ADC (0.4 µs conversion), and operating voltage range of 2.0–3.6 V. It integrates calendar RTC with alarm, four 16-bit general-purpose timers, and supports 5 V-tolerant I/Os-used in industrial sensor nodes and smart metering front-ends requiring low-power operation and robust serial communication.

For engineers reviewing the STM32G030C8T6 datasheet, STM32G030C8T6 pinout, STM32G030C8T6 application, or STM32G030C8T6 equivalent, key selection criteria include its LQFP48 package, 64 MHz max CPU frequency, hardware parity on SRAM, SWD debug interface, and Fast-mode Plus I²C (1 Mbit/s) with extra current sink capability.

Technical Context

The device implements a single-core Arm Cortex-M0+ with MPU, executing instructions at up to 64 MHz using internal 16 MHz RC oscillator with PLL or external 4–48 MHz crystal. Its memory subsystem includes 64 KB flash with readout protection and 8 KB SRAM with hardware parity checking for ECC-like error detection.

Clock management supports multiple sources: 32 kHz LSE with calibration, 16 MHz HSI, 32 kHz LSI, and PLL-based system clock derivation. Power architecture enables Sleep, Stop, and Standby modes with VBAT backup for RTC and registers-wakeup from Stop mode possible via I²C event or USART activity.

FAQ

Does STM32G030C8T6 support USB connectivity?

No, the STM32G030C8T6 does not include a USB peripheral. It relies on USART, SPI, or I²C for host communication. For USB-enabled variants, consider the STM32G071 or STM32G0B1 series, which integrate full-speed USB 2.0 interfaces with built-in PHY and descriptors.

What is the maximum operating temperature for STM32G030C8T6?

The STM32G030C8T6 is rated for operation from –40 °C to +85 °C ambient temperature. This industrial-grade range is validated per ST's production test flow and applies to all LQFP48 packages under specified voltage and load conditions per DS12991 Rev 6 Section 5.3.1.

Can the internal 16 MHz RC oscillator be used as the system clock without calibration?

Yes, the internal 16 MHz HSI oscillator can serve as the system clock source without calibration, with ±1% typical accuracy at 25 °C. For tighter timing requirements, ST recommends enabling the HSI calibration feature using the LSE or external reference, improving stability to ±0.5% across temperature.

Is SWD debug supported on all pins of the LQFP48 package?

SWD debug uses only two dedicated pins: PA13 (SWDIO) and PA14 (SWCLK). These pins are fixed-function in debug mode and cannot be reassigned to other peripherals while debugging is active. No other LQFP48 pins provide SWD functionality.
