STM32F030R
STM32F030R - Cortex-M0 48MHz MCU, 64KB Flash, 64-LQFP | ST
The STMicroelectronics STM32F030R is a value-line ARM Cortex-M0 32-bit RISC microcontroller operating at 48 MHz, integrating up to 64 KB of Flash memory and housed in a 64-pin LQFP package. Operating from a 2.4 V to 3.6 V supply, the device delivers 38.4 DMIPS while consuming only a few milliamps in run mode, making it a leading low-power option in the entry-level STM32 family. This particular variant is the STM32F030R8T6 (64-pin LQFP, 64 KB Flash, industrial -40C to +85C), one of the most widely adopted members of the STM32F030 series.
A microcontroller (MCU) is a single-chip computer that integrates a processor core, memory (Flash for code, SRAM for data), and a rich set of programmable peripherals on a single die. The Cortex-M0 is the smallest and most energy-efficient member of the ARM Cortex-M processor family, designed for cost-sensitive, deterministic embedded applications. Within the ST portfolio, the STM32F0 sits below the Cortex-M3/M4 STM32F1/F3 lines and above the 8-bit STM8, occupying the mainstream 32-bit entry point. The STM32F030 specifically targets cost-down designs that previously used 8/16-bit MCUs but now require 32-bit performance, USB-less connectivity, and ST's strong STM32 tool ecosystem (CubeMX, HAL, Standard Peripheral Library).
Key features include a 12-bit 1 MSPS ADC with up to 16 channels, multiple 16-bit and 32-bit timers (including PWM, input capture, and quadrature encoder support), two I2C, two SPI (one I2S-capable), one USB 2.0 Full-Speed (device mode, on R8/C0/C8/CB parts), one CAN 2.0B (RC0/RC8 variants), and up to 55 GPIO. An integrated 8 MHz HSI RC oscillator with 1% accuracy and a 40 kHz LSI reduce external component count. The 64-LQFP package provides 64 pins at 10 mm x 10 mm body, including dedicated pins for BOOT0, NRST, OSC_IN/OSC_OUT, and full SWD debug.
The architecture pairs a 3-stage pipeline Cortex-M0 core with a 32-bit AHB-Lite bus and a multi-channel DMA controller. The Nested Vectored Interrupt Controller (NVIC) handles up to 32 maskable interrupts with deterministic 16-cycle latency. A cyclic redundancy check (CRC) peripheral, two watchdogs (IWDG/WWDG), and a 7-channel DMA accelerate data movement without CPU overhead.
Typical applications include consumer appliances (washing machines, induction cookers), industrial sensor hubs, USB HID peripherals, low-cost CAN nodes, smart meters, and home automation. The compact LQFP-64 footprint and 48 MHz clock headroom make it a common choice for migration paths from 8-bit PIC/AVR designs into the STM32 ecosystem.
When designing with the STM32F030R, ensure each VDD/VDDA pin pair has a 100 nF decoupling capacitor placed within 2 mm of the pin, and consider the BOOT0 strap resistor for boot mode selection. The 64-LQFP package has limited thermal headroom at high ambient temperatures, so verify junction temperature under worst-case load.
