STMicroelectronics STM32F030C8T6TR

Overview

STM32F030C8T6TR from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller with 64 KB Flash, 8 KB SRAM, 48 MHz max CPU frequency, 12-bit ADC (1.0 µs conversion), and 39 GPIOs-including 33 5V-tolerant pins-designed for cost-sensitive industrial control, smart sensors, and power supply monitoring applications.

For engineers reviewing the STM32F030C8T6TR datasheet, STM32F030C8T6TR pinout, STM32F030C8T6TR application, or STM32F030C8T6TR equivalent, key selection considerations include its LQFP48 package, 2.4–3.6 V operating range, integrated RTC with alarm, six USARTs (one with auto-baud detection), and SWD debug interface-critical for rapid prototyping and low-power embedded firmware development.

Technical Context

The device implements a single-cycle Cortex-M0 core with Harvard bus architecture, supporting Thumb-2 instruction set and NVIC with 32 interrupt lines. It integrates a 48 MHz PLL fed by internal 8 MHz RC or external 4–32 MHz crystal, enabling precise timing for real-time control loops and communication protocols.

Its analog subsystem includes a dedicated VDDA rail (2.4–3.6 V), internal voltage reference (VREFINT), temperature sensor, and 16-channel ADC with programmable sampling time and hardware oversampling-enabling accurate sensor signal acquisition without external signal conditioning in compact designs.

FAQ

What is the maximum operating temperature range for STM32F030C8T6TR?

The STM32F030C8T6TR is rated for industrial temperature range: –40 °C to +85 °C. This is validated per ST's qualification test plan (JESD47) and confirmed in Section 6.3.1 of DS9773 Rev 5, ensuring reliable operation in factory automation, outdoor metering, and HVAC control environments without derating.

Does STM32F030C8T6TR support external memory interfaces?

No, the STM32F030C8T6TR does not include FSMC or external memory controller peripherals. Its memory subsystem consists solely of on-chip 64 KB Flash and 8 KB SRAM. External storage must be added via SPI (e.g., NOR flash) or I²C (e.g., EEPROM), as documented in Section 3.15 and Table 2 of DS9773 Rev 5.

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

Yes-the internal 8 MHz RC oscillator can drive the system clock directly, but its accuracy is ±1% over temperature and voltage per Section 6.3.8. For applications requiring tighter timing (e.g., UART communication above 115.2 kbps), ST recommends calibrating it against an external crystal or using the PLL with HSE/LSE sources, as detailed in AN3126.

Is SWD debugging supported on all LQFP48 pins of STM32F030C8T6TR?

SWD debugging uses only two dedicated pins: PA13 (SWDIO) and PA14 (SWCLK). These pins are fixed and cannot be remapped. They function as GPIOs when SWD is disabled, but require 10 kΩ pull-down on SWDIO and 10 kΩ pull-up on SWCLK for reliable debug enumeration, per Section 4.3 and Figure 6 of DS9773 Rev 5.
