Product details
Overview
STM32F030F4P6 from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller in TSSOP20 package, operating at up to 48 MHz with 16 KB Flash and 4 KB SRAM. It integrates a 12-bit ADC (1.0 µs conversion), six USARTs (one with auto baud rate detection), two I²C interfaces (one supporting Fast Mode Plus), and five-channel DMA - deployed in industrial sensor nodes requiring low-cost, compact MCU solutions with analog sensing and serial communication.
For engineers reviewing the STM32F030F4P6 datasheet, STM32F030F4P6 pinout, STM32F030F4P6 application, or STM32F030F4P6 equivalent, key selection criteria include its TSSOP20 footprint, 5V-tolerant I/Os (up to 19 pins), 2.4–3.6 V supply range, RTC with alarm, and SWD debug interface - all critical for space-constrained embedded control designs.
Technical Context
The STM32F030F4P6 implements a single-cycle Cortex-M0 core with Harvard bus architecture, tightly coupled NVIC and SysTick timer, and supports boot from system memory, main Flash, or SRAM. Its clock tree includes internal 8 MHz RC (with x6 PLL), 40 kHz LSI, and external 4–32 MHz HSE or 32.768 kHz LSE options - enabling precise timing for real-time control loops and RTC calendar functions.
Power management features POR/PDR, programmable voltage detector (PVD), and three low-power modes (Sleep, Stop, Standby) with sub-µA standby current. The 12-bit ADC operates across 0–3.6 V input range with separate VDDA supply and supports up to 16 channels via multiplexing - essential for multi-sensor signal acquisition in battery-powered devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time execution of control algorithms with <100 ns interrupt latency. |
| Flash Memory | 16 KB - sufficient for firmware with USB HID stack, sensor fusion, and communication protocol stacks in compact applications. |
| SRAM | 4 KB with hardware parity - ensures data integrity for critical variables and stack operations in safety-aware firmware. |
| ADC | 12-bit, 1.0 µs conversion time, 16-channel mux - supports simultaneous sampling of temperature, voltage, and current sensors at ≥1 MSPS effective throughput. |
| I/O Pins | 19 GPIOs, 5V tolerant - allows direct interfacing with legacy 5V logic, industrial sensors, and discrete actuators without level shifters. |
| Communication | 2× I²C (1× Fast Mode Plus), 6× USART (1× auto-baud), 2× SPI - enables concurrent Modbus RTU, I²C sensor hub, and UART debug logging. |
| Debug Interface | Serial Wire Debug (SWD) - provides non-intrusive real-time debugging and flash programming using standard ST-LINK v2/v3 probes. |
Pinout & Package
TSSOP20 (6.4 × 4.4 mm, 0.65 mm pitch) - RoHS-compliant, ECOPACK®2-qualified package optimized for automated SMT assembly and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Digital power supply | 2.4–3.6 V input; powers core, GPIOs, and digital peripherals - requires local 100 nF decoupling. |
| VDDA | Analog power supply | 2.4–3.6 V dedicated rail for ADC and reset circuitry - must be filtered separately from VDD. |
| VSS | Digital ground | Reference for digital I/O and core logic - connect to PCB ground plane with low-inductance path. |
| VSSA | Analog ground | Reference for ADC and analog comparators - isolate from digital ground at single-point star connection. |
| PA0–PA9 | General-purpose I/O | 10 pins with alternate functions (USART, I²C, SPI, TIM); all 5V tolerant except PA9 (USART1_TX) in open-drain mode. |
| NRST | Active-low reset input | Externally driven reset with internal pull-up; accepts 1.65–5.5 V logic - compatible with pushbutton or supervisor ICs. |
| SWDIO / SWCLK | Debug interface signals | Two-pin SWD port for programming and debugging - no external pull-ups required per ST reference design. |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant I/Os | 19 pins withstand 5.5 V inputs - eliminates level translators when interfacing with 5V sensors, displays, or legacy controllers. |
| RTC with alarm & wakeup | Calendar function with alarm interrupt and periodic wake-from-Stop - enables ultra-low-power sensor polling every 1–60 seconds. |
| Independent watchdog (IWDG) | LSI-driven 12-bit counter with windowed mode - prevents firmware lockup in unattended industrial nodes without external supervision. |
| Hardware CRC unit | Dedicated 32-bit polynomial engine (CRC-32, CRC-16) - accelerates firmware OTA validation and EEPROM data integrity checks. |
| Fast-mode Plus I²C | 1 Mbit/s operation with 20 mA sink capability - supports robust communication with multiple slave sensors on noisy factory-floor buses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F030C6T6 | LQFP48 package, 32 KB Flash, 6 KB SRAM, 39 GPIOs - larger footprint and higher memory capacity. | Suitable for designs requiring more peripherals (e.g., dual SPI + I²C + USB), but incompatible pinout and layout. | Select when expanding functionality beyond TSSOP20 pin count limits; requires full PCB redesign. |
| EFM32HG309F64 | Silicon Labs ARM Cortex-M0+, 64 KB Flash, 8 KB RAM, integrated DC-DC converter - lower active current (110 µA/MHz). | Better suited for battery life-critical applications; lacks Fast Mode Plus I²C and 5V-tolerant I/Os. | Choose for ultra-low-power portable devices where 5V interface compatibility is not required. |
Compared with STM32F030C6T6, the F4P6 trades memory and I/O count for minimal size and cost; versus EFM32HG309F64, it prioritizes industrial I/O robustness and ecosystem maturity over sub-mA sleep current - making it optimal for cost-sensitive, space-constrained control nodes needing 5V interoperability.

FAQ
Does STM32F030F4P6 support USB connectivity?
No, the STM32F030F4P6 does not integrate a USB peripheral. It belongs to the value-line F0 series, which omits USB PHY and related registers to reduce cost and die size. For USB-enabled variants, consider STM32F042x6 or STM32F070x6, which include USB 2.0 FS device controllers and required internal transceivers.
What is the maximum operating temperature range for STM32F030F4P6?
The STM32F030F4P6 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 of DS9773 Rev 5, specifying ambient operating conditions under VDD = 2.4–3.6 V. No extended (–40 °C to +105 °C) or automotive grade variant exists for this specific part number.
Can the internal 8 MHz RC oscillator be used as system clock without calibration?
Yes, the internal 8 MHz RC oscillator can serve as system clock without calibration, but its accuracy is ±1% over temperature and voltage - insufficient for UART communication above 9600 baud without oversampling. For reliable serial communication, ST recommends calibrating the HSI using an external clock source or using the PLL with HSE/LSE for tighter timing control.
Is SWD debug supported on all TSSOP20 pins of STM32F030F4P6?
SWD debug is supported exclusively on pins PA13 (SWDIO) and PA14 (SWCLK) - both located on the TSSOP20 package (pins 17 and 18 respectively). These pins are dedicated to SWD and cannot be reassigned to other functions during debug session. No other TSSOP20 pins provide debug capability; NRST is optional for reset control but not required for basic SWD operation.
