STMicroelectronics STM32F030C6T6TR

Overview

STM32F030C6T6TR from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller in LQFP48 package, operating at up to 48 MHz with 32 KB Flash and 4 KB SRAM (HW parity), integrated 12-bit ADC (1.0 µs conversion), six USARTs (one with auto baud rate detection), and five-channel DMA - deployed in industrial sensor nodes, smart metering front-ends, and low-cost motor control modules.

For engineers reviewing the STM32F030C6T6TR datasheet, STM32F030C6T6TR pinout, STM32F030C6T6TR application, or STM32F030C6T6TR equivalent, key selection criteria include 5V-tolerant I/O count (up to 39 pins), RTC calendar support with periodic wakeup from Stop/Standby, Fast Mode Plus I²C (1 Mbit/s), dual SPI (18 Mbit/s), and SWD debug interface compatibility.

Technical Context

The STM32F030C6T6TR implements a single-cycle Cortex-M0 core with Harvard bus architecture, supporting Thumb-2 instruction set and NVIC with 32 interrupt vectors. Its clock system integrates dual oscillators: 4–32 MHz HSE for main PLL input and 32.768 kHz LSE for RTC, plus internal 8 MHz HSI (±1% typical) with x6 PLL for precise 48 MHz system clock generation.

Peripheral interconnect uses AHB/APB2/APB1 buses with dedicated DMA channels servicing ADC, timers, and USARTs. The 12-bit ADC features 16-channel multiplexing, separate VDDA supply (2.4–3.6 V), and built-in temperature sensor + VREFINT reference - enabling standalone calibration without external components.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32F030C6T6TR operates at up to 48 MHz using its internal 8 MHz HSI oscillator with x6 PLL, or external 4–32 MHz crystal. It supports a digital supply range of 2.4–3.6 V (VDD) and analog supply of 2.4–3.6 V (VDDA), with all I/Os rated for 5V tolerance regardless of VDD level - enabling robust interfacing in mixed-voltage systems.

Does this MCU support hardware CRC and memory parity?

Yes, the STM32F030C6T6TR includes a dedicated CRC calculation unit supporting CRC-32 polynomial (0x04C11DB7) for firmware image validation, and its 4 KB SRAM implements hardware parity checking with automatic fault detection and NMI generation - meeting basic functional safety requirements for IEC 61508 SIL-2 subsystems.

How many 5V-tolerant I/O pins does the LQFP48 package provide?

The STM32F030C6T6TR in LQFP48 offers 39 5V-tolerant I/O pins across GPIO ports A, B, and C (PA0–PA15, PB0–PB15, PC13–PC15), confirmed in ST's DS9773 Rev 5 Section 4 and Table 11. This eliminates external level shifters when connecting to 5V sensors, displays, or legacy peripherals.

Is an external crystal required for RTC operation?

No - the RTC can operate from the internal 32 kHz LSI oscillator (40 kHz ±10%), but for calendar accuracy better than ±120 ppm, ST recommends using the external 32.768 kHz LSE crystal with calibration register (RCC_BDCR) adjustment. The LSE circuit is fully integrated with load capacitors supported on-chip (12.5 pF typical), reducing BOM count.
