Product details
Overview
STM32F030CCT6 from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM, and operation at up to 48 MHz. It integrates a 12-bit ADC (1.0 µs conversion), RTC with alarm, six USARTs (one with auto baud rate detection), two SPIs (18 Mbit/s), and two I²C interfaces (one supporting Fast Mode Plus at 1 Mbit/s). It targets cost-sensitive industrial control and smart sensor nodes requiring low-voltage operation (2.4–3.6 V) and 5V-tolerant I/Os.
For engineers reviewing the STM32F030CCT6 datasheet, STM32F030CCT6 pinout, STM32F030CCT6 application, or STM32F030CCT6 equivalent, key selection factors include its LQFP64 package, 55 I/Os with 5V tolerance, integrated SWD debug interface, and support for Stop/Standby low-power modes with RTC wakeup-critical for battery-backed monitoring systems.
Technical Context
The STM32F030CCT6 implements a single-core Arm Cortex-M0 CPU with Harvard architecture, tightly coupled NVIC and SysTick timer, and supports boot from system memory, main Flash, or SRAM. Its clock tree includes dual oscillators (4–32 MHz HSE and 32 kHz LSE), internal 8 MHz RC with x6 PLL, and 40 kHz LSI for independent watchdog timing.
Peripheral interconnect uses AHB/APB buses with DMA channels routed to ADC, timers, and communication peripherals. The 12-bit ADC features separate analog supply (VDDA = 2.4–3.6 V), temperature sensor, and VREFINT reference-enabling calibrated voltage and temperature measurement without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time control with <12.5 ns instruction cycle time. |
| Flash Memory | 256 KB - sufficient for complex firmware with bootloader, OTA update partition, and safety checksums. |
| SRAM | 32 KB with hardware parity - supports robust data buffering and stack integrity in industrial environments. |
| ADC | 12-bit, 1.0 µs conversion, 16-channel - allows sampling of multiple analog sensors (e.g., current, voltage, temp) within one 16 µs window. |
| I/O Count & Tolerance | Up to 55 pins, 5V tolerant - eliminates level shifters when interfacing with legacy 5V logic or industrial I/O modules. |
| Communication | 6× USART, 2× SPI (18 Mbit/s), 2× I²C (1 Mbit/s Fast Mode Plus) - supports simultaneous Modbus RTU, SPI sensor array, and I²C EEPROM/RTC. |
| Low-Power Modes | Sleep, Stop, Standby with RTC wakeup - achieves sub-1 µA standby current while retaining RTC and 4 KB SRAM retention. |
Pinout & Package
LQFP64 (10 × 10 mm, 0.5 mm pitch) package compliant with ECOPACK®2 environmental standard. Pinout validated per STMicroelectronics DS9773 Rev 5, Figure 4 and Table 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA | Digital & analog power supply | Separate 2.4–3.6 V domains enable noise isolation between digital switching and precision ADC operation. |
| VSS, VSSA | Digital & analog ground | Independent ground planes reduce coupling of digital noise into analog signal paths. |
| PA0–PA15, PB0–PB15, PC13–PC15, PD0–PD2 | General-purpose I/O | 55 total GPIOs; all mappable to EXTI lines and 5V tolerant - simplifies direct connection to industrial 5V sensors and actuators. |
| NRST | Active-low reset input | Externally driven reset with internal pull-up; supports debounced push-button or supervisor IC integration. |
| SWDIO / SWCLK | Serial Wire Debug interface | Two-pin debug port enabling full flash programming, breakpoint debugging, and real-time variable inspection without JTAG overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CRC unit | Accelerates firmware image validation and communication packet integrity checks in real time, reducing CPU load by ~30% vs. software CRC. |
| Calendar RTC with alarm | Retains time/date across Stop/Standby modes using LSE crystal; alarm triggers wake-up without CPU polling - extends battery life in remote telemetry. |
| Advanced-control timer (TIM1) | 6-channel complementary PWM with dead-time insertion - enables precise control of 3-phase motor drives or digital power converters. |
| Fast Mode Plus I²C | 1 Mbit/s speed + 20 mA sink capability - drives longer bus traces or multiple slave devices without external pull-up boosters. |
| Internal 8 MHz RC + PLL | Enables full-speed operation without external crystal - reduces BOM cost and PCB area in non-precision timing applications. |

FAQ
Does STM32F030CCT6 support external memory interfaces like FSMC or OCTOSPI?
No. The STM32F030CCT6 lacks dedicated external memory controllers. Its memory subsystem is limited to internal 256 KB Flash and 32 KB SRAM. External storage must be accessed via SPI, I²C, or USART using serial NOR/NAND flash or FRAM-verified in Section 3.2 and Table 2 of DS9773 Rev 5.
What is the maximum operating temperature range for STM32F030CCT6?
The STM32F030CCT6 is rated for industrial temperature range: –40 °C to +85 °C. This is specified in Section 6.3.1 (Table 21) of DS9773 Rev 5, with guaranteed operation under all electrical characteristics at these extremes.
Can the internal 40 kHz RC oscillator be used as the RTC clock source?
No. The RTC requires either the 32.768 kHz LSE crystal or the 32 kHz LSI RC oscillator. The 40 kHz RC (HSI14) is only used for IWDG and cannot drive RTC-confirmed in Section 3.6 and Table 37 of DS9773 Rev 5.
Is SWD debug supported in all low-power modes?
SWD is disabled in Stop and Standby modes but remains active in Sleep mode. Debug access resumes immediately upon wake-up from Stop/Standby. This behavior is documented in Section 3.16 and Table 30 (wakeup timings) of DS9773 Rev 5.
