STMicroelectronics STM32F030CCT6TR

Overview

STM32F030CCT6TR from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM, and operation at 2.4–3.6 V. It integrates a 12-bit 1.0 µs ADC (16-channel), six USARTs (one with auto baud rate detection), two SPIs (18 Mbit/s), and an advanced-control timer for six-channel PWM-used in industrial sensor nodes requiring deterministic real-time control and low-power operation.

For engineers reviewing the STM32F030CCT6TR datasheet, STM32F030CCT6TR pinout, STM32F030CCT6TR application, or STM32F030CCT6TR equivalent, key selection criteria include its LQFP48 package, 48 MHz max CPU frequency, 5V-tolerant I/Os (up to 55 pins), RTC with alarm/wakeup, and SWD debug interface-critical for cost-sensitive embedded control designs with constrained PCB area.

Technical Context

The device implements a single-core Arm Cortex-M0 with Harvard architecture, supporting Thumb-2 instruction set and nested vectored interrupt controller (NVIC) with up to 32 interrupts. Its clock system includes dual oscillators: 4–32 MHz HSE for precision timing and 32 kHz LSE for RTC, plus internal 8 MHz HSI (±1% typical) with x6 PLL for 48 MHz system clock.

Power management features POR/PDR, programmable voltage detectors, and three low-power modes (Sleep, Stop, Standby) with wake-up via EXTI lines, RTC alarm, or I2C address match. The ADC uses separate analog supply (VDDA = 2.4–3.6 V) and supports hardware oversampling and injected channel sequencing for sensor signal acquisition.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F030CCT6TR achieves a maximum CPU frequency of 48 MHz using its internal 8 MHz HSI oscillator with a 6× PLL multiplier. This configuration requires no external crystal and maintains ±1% accuracy over temperature and voltage. Alternatively, a 4–32 MHz external crystal can drive the PLL for higher precision timing in applications like motor control synchronization.

Does this MCU support hardware encryption or secure boot?

No, the STM32F030CCT6TR does not include hardware cryptographic accelerators or secure boot circuitry. It lacks AES, DES, or public-key engines, and has no dedicated ROM-based bootloader with signature verification. Security relies on software-implemented measures and external secure elements if required for certification (e.g., IEC 62443).

Can the ADC operate independently while the CPU is in Stop mode?

Yes-the ADC can be triggered by RTC alarm or external event while the CPU is in Stop mode, and conversion results can be stored in memory via DMA without waking the core. This enables ultra-low-power sensor sampling (e.g., temperature every 10 seconds) with total system current below 5 µA during idle periods.

Is the LQFP48 package lead-free and RoHS compliant?

Yes, the STM32F030CCT6TR in LQFP48 packaging is fully RoHS compliant and lead-free per EU Directive 2011/65/EU. It carries ST's ECOPACK®2 certification, confirming compliance with halogen-free materials and strict substance restrictions including cadmium, mercury, hexavalent chromium, PBB, and PBDE.
