STMicroelectronics STM32F030K6T6TR

Overview

STM32F030K6T6TR from STMicroelectronics is a value-line Arm® Cortex®-M0 32-bit microcontroller in TSSOP20 package, delivering up to 48 MHz operation, 32 KB Flash, 4 KB SRAM with hardware parity, and integrated 12-bit ADC (1.0 µs conversion), six USARTs, two SPIs (18 Mbit/s), and two I²C interfaces with Fast Mode Plus (1 Mbit/s). It targets cost-sensitive industrial control and smart sensor nodes requiring low-voltage operation (2.4–3.6 V) and robust 5V-tolerant I/Os.

For engineers reviewing the STM32F030K6T6TR datasheet, STM32F030K6T6TR pinout, STM32F030K6T6TR application, or STM32F030K6T6TR equivalent, key selection criteria include its TSSOP20 footprint for space-constrained PCBs, 55 fast I/Os with 5V tolerance, RTC with alarm and wakeup from Stop/Standby, SWD debug interface, and support for auto baud rate detection on one USART - all critical for embedded firmware development and BOM optimization.

Technical Context

The STM32F030K6T6TR implements an Arm Cortex-M0 core with Harvard architecture, supporting Thumb-2 instruction set and nested vectored interrupt controller (NVIC) for deterministic real-time response. Its clock system integrates dual oscillators: a 4–32 MHz external crystal and internal 8 MHz RC with x6 PLL for precise 48 MHz system clock generation.

Power management includes POR/PDR, three low-power modes (Sleep, Stop, Standby), and separate analog supply (VDDA = VDD to 3.6 V) enabling independent ADC and RTC operation. The 12-bit ADC supports up to 16 channels with dedicated VREFINT and temperature sensor, calibrated at factory for ±2°C accuracy over –40 to +85°C.

FAQ

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

The STM32F030K6T6TR achieves a maximum system clock of 48 MHz using its internal 8 MHz RC oscillator multiplied by a programmable x6 PLL. This configuration avoids external crystal cost while maintaining timing precision within ±1% over temperature and voltage ranges. External 4–32 MHz crystals may also be used for higher accuracy applications.

Does this MCU support hardware parity checking on SRAM?

Yes, the STM32F030K6T6TR implements hardware parity checking on its entire 4 KB SRAM block. Parity errors trigger a HardFault exception, allowing firmware to detect and handle memory corruption events - a key requirement for functional safety compliance in industrial control applications.

Can the ADC measure signals beyond the VDDA supply range?

No. The ADC input voltage range is strictly 0 to VDDA (2.4–3.6 V). Input signals exceeding VDDA risk damage or erroneous conversions. For 5V sensor interfacing, external resistive dividers or rail-to-rail op-amp conditioning circuits are required to scale inputs into the valid ADC range.

Is the TSSOP20 package suitable for reflow soldering and automated assembly?

Yes, the STM32F030K6T6TR in TSSOP20 package is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C. Its 0.65 mm pitch and gull-wing leads ensure reliable placement and solder joint formation in high-volume SMT lines.
