STMicroelectronics STM32F030C6T6

Overview

STM32F030C6T6 from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller with 32 KB Flash, 4 KB SRAM, 48 MHz max CPU frequency, 12-bit ADC (1.0 µs conversion), and 39 GPIOs-including 37 with 5V tolerance-designed for cost-sensitive industrial control, smart sensors, and power supply monitoring systems.

For engineers reviewing the STM32F030C6T6 datasheet, STM32F030C6T6 pinout, STM32F030C6T6 application, or STM32F030C6T6 equivalent, key selection criteria include its LQFP48 package footprint, 2.4–3.6 V single-supply operation, integrated RTC with alarm, six USARTs (one with auto-baud detection), and SWD debug interface compatibility.

Technical Context

The STM32F030C6T6 implements a fixed-function Cortex-M0 core with Harvard bus architecture, tightly coupled NVIC supporting up to 32 interrupts, and a dedicated CRC calculation unit for firmware integrity verification. Its clock system integrates dual oscillators: a 4–32 MHz HSE for precision timing and an internal 8 MHz HSI with x6 PLL for flexible system clock generation.

Power management includes POR/PDR circuitry, three low-power modes (Sleep/Stop/Standby), and separate analog supply (VDDA) routing for ADC and RTC stability. All I/Os support external interrupt mapping, and five DMA channels enable efficient peripheral-to-memory data transfers without CPU intervention.

FAQ

Does STM32F030C6T6 support external crystal oscillators?

Yes, it supports 4–32 MHz high-speed external (HSE) crystals for precise system clocking and a 32.768 kHz low-speed external (LSE) crystal for RTC accuracy. Both require external load capacitors per datasheet Table 31 and Table 34, and the HSE can be used as PLL input to achieve 48 MHz CPU frequency.

What is the maximum operating temperature range for STM32F030C6T6?

The STM32F030C6T6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per datasheet Section 6.3.1 and applies to all electrical characteristics, including Flash endurance (10 k write/erase cycles) and ADC accuracy (±3 LSB INL at 25 °C, ±5 LSB over full range).

Can the internal 8 MHz RC oscillator be used without calibration?

Yes, the internal 8 MHz HSI oscillator operates without calibration and meets ±1% accuracy over temperature and voltage per datasheet Table 35. It is factory-trimmed and suitable for UART communication at 9600 bps or system startup before HSE stabilization, though external crystal is recommended for time-critical applications like RTC or high-speed USB.

Is SWD debug supported on all LQFP48 pins of STM32F030C6T6?

SWD debug uses only two dedicated pins: PA13 (SWDIO) and PA14 (SWCLK). These pins are fixed-function for debug and cannot be remapped. They are electrically compatible with ST-LINK/V2 and other CMSIS-DAP compliant debuggers, requiring no external components beyond standard 10 kΩ pull-down on SWDIO for hot-plug safety.
