Product details
Overview
STM32F030K6T6 from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller in TSSOP20 package, featuring 32 KB Flash, 4 KB SRAM with hardware parity, 48 MHz max CPU frequency, 12-bit 1.0 µs ADC (16-channel), and 5V-tolerant I/Os. It targets cost-sensitive industrial control, smart sensors, and basic HMI applications requiring low-voltage operation (2.4–3.6 V) and integrated peripherals including two USARTs, one SPI, one I²C, and RTC with alarm.
For engineers reviewing the STM32F030K6T6 datasheet, STM32F030K6T6 pinout, STM32F030K6T6 application, or STM32F030K6T6 equivalent, key selection criteria include Flash/SRAM size, 5V-tolerant GPIO count, ADC resolution and speed, low-power mode support (Stop/Standby), and TSSOP20 footprint compatibility with space-constrained PCB layouts.
Technical Context
The STM32F030K6T6 implements an Arm 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 integrates dual oscillators - 4–32 MHz HSE and 32.768 kHz LSE - plus internal 8 MHz HSI (with x6 PLL) and 40 kHz LSI for RTC and watchdogs.
Peripheral interconnect uses AHB/APB buses with DMA channel arbitration for concurrent ADC, USART, and SPI transfers. The 12-bit ADC operates across 0–3.6 V input range with dedicated VDDA supply and includes temperature sensor and VREFINT channels calibrated at factory for ±2 °C and ±1.5 % accuracy respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time control with Thumb-2 instruction set and 3-stage pipeline. |
| Flash Memory | 32 KB - sufficient for firmware with USB HID stack, sensor fusion, or motor control algorithms in compact code. |
| SRAM | 4 KB with HW parity - supports safe data buffering and stack operations in safety-aware embedded systems. |
| ADC | 12-bit, 1.0 µs conversion time, 16-channel - delivers 1 MSPS sampling for analog monitoring of multiple sensors or power rails. |
| I/O Voltage Tolerance | 5V tolerant on all pins - eliminates level-shifting components when interfacing with legacy 5V logic or industrial I/O modules. |
| Low-Power Modes | Sleep, Stop, Standby with RTC wakeup - achieves <1 µA standby current, enabling battery-powered operation for >1 year on CR2032. |
| Package | TSSOP20, 6.4 × 4.4 mm - surface-mount compatible with automated assembly and suitable for high-density consumer electronics PCBs. |
Pinout & Package
TSSOP20 package: 20-pin thin shrink small-outline package, 0.65 mm pitch, body size 6.4 × 4.4 mm, exposed pad optional, RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Digital power supply | 2.4–3.6 V main supply; decoupling capacitor required near pin for noise immunity. |
| VSS | Digital ground | Reference return path for digital logic and I/O drivers; must be connected to system GND plane. |
| VDDA | Analog power supply | Separate 2.4–3.6 V supply for ADC and reset circuitry; requires independent filtering from VDD. |
| VSSA | Analog ground | Isolated analog reference return; must tie to VSS at single point to avoid noise coupling into ADC. |
| PA0–PA9 | General-purpose I/O | 10 pins with 5V tolerance, configurable as GPIO, USART TX/RX, SPI SCK/MOSI/MISO, or ADC inputs. |
| NRST | Active-low reset input | Asynchronous reset trigger; internal pull-up; accepts 1.65–5.5 V logic levels for robust system recovery. |
| BOOT0 | Boot mode select | High at power-on forces boot from system memory; used for factory bootloader or DFU recovery. |
| SWDIO/SWCLK | Serial Wire Debug interface | Two-pin debug port supporting programming, breakpointing, and real-time variable inspection without JTAG overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CRC unit | Accelerates firmware integrity checks and communication frame validation without CPU load. |
| Calendar RTC with alarm | Enables time-stamped logging and scheduled wakeups from Stop/Standby modes using 32.768 kHz crystal. |
| Five-channel DMA controller | Offloads data movement between peripherals (e.g., ADC→memory, USART→buffer), freeing CPU for computation. |
| Independent & window watchdogs | Provides dual-layer fail-safe reset: IWDG for simple timeout, WWDG for early detection of software hang during critical sequences. |
| Fast Mode Plus I²C | Supports 1 Mbit/s data rate and 20 mA sink capability on one I²C interface - drives long traces or multiple slave devices reliably. |
Applications
| Industrial Sensor Node | Smart Home Actuator |
|---|---|
Use Scenario: Battery-powered temperature/humidity node transmitting data via UART-to-LoRa module. IC Role / Device Role / Timing Role: Main controller executing sensor readout, calibration, and serial protocol framing; RTC provides timestamping and periodic wakeups.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F030F4P6 | 16 KB Flash, 4 KB SRAM, same TSSOP20 package, identical peripheral set except no RTC calendar function. | Lacks calendar RTC and alarm - unsuitable for time-stamped logging or scheduled wakeups. | Select when RTC functionality is unnecessary and cost reduction is prioritized over timekeeping features. |
| STM32F042F4P6 | Same Flash/SRAM, adds USB 2.0 FS device interface and enhanced debug features; requires additional USB pull-up resistor and VBUS sensing. | Enables direct USB connectivity but increases BOM count and layout complexity for USB routing and ESD protection. | Choose when native USB HID or CDC interface is required instead of UART-to-bridge solutions. |
Compared with STM32F030F4P6, the STM32F030K6T6 offers +16 KB Flash and full RTC calendar support at identical footprint; versus STM32F042F4P6, it trades USB capability for lower system cost and simpler layout, making it optimal for non-USB sensor and control nodes.

FAQ
Does STM32F030K6T6 support external crystal oscillators?
Yes, it supports 4–32 MHz high-speed external (HSE) crystals for precise system clock generation and a 32.768 kHz low-speed external (LSE) crystal for RTC operation. Both require external load capacitors per datasheet recommendations - typically 12–22 pF for HSE and 12.5 pF for LSE - and proper PCB layout with short traces and ground guard rings.
What is the maximum operating temperature range for STM32F030K6T6?
The STM32F030K6T6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated across all electrical characteristics including Flash programming, ADC linearity, and I/O drive strength. Operation beyond this range may cause parameter drift or functional failure, and is not guaranteed by STMicroelectronics.
Can the internal 8 MHz RC oscillator be used as system clock without calibration?
Yes, the internal 8 MHz HSI oscillator can serve as system clock source without external components, but its factory-trimmed accuracy is ±1 % over temperature and voltage. For applications requiring tighter timing - such as UART baud rate matching or precise PWM - ST recommends enabling HSI calibration via RCC_CR register or using the PLL with HSE for improved stability.
How many I/O pins on STM32F030K6T6 support external interrupt capability?
All 10 general-purpose I/O pins (PA0–PA9) are individually mappable to external interrupt vectors via EXTI lines. Each pin can trigger rising/falling/both-edge interrupts independently, and priority is managed through NVIC configuration registers - enabling responsive event-driven designs like button presses or sensor alerts without polling overhead.
