STMicroelectronics STM32G030K6T6

Overview

STM32G030K6T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller in LQFP32 package, operating up to 64 MHz with 64 KB Flash and 8 KB SRAM. It integrates two USARTs (one with LIN/ISO7816/IrDA), a 12-bit ADC (0.4 µs conversion, up to 16 external channels), RTC with alarm, and supports 2.0–3.6 V supply for industrial sensor nodes and smart metering interfaces.

For engineers reviewing the STM32G030K6T6 datasheet, STM32G030K6T6 pinout, STM32G030K6T6 application, or STM32G030K6T6 equivalent, key selection criteria include its 32-pin LQFP footprint, 64 MHz CPU clock, 12-bit ADC accuracy (±1 LSB INL), dual USART with LIN support, and low-power Stop/Standby modes enabling battery-backed operation in edge sensing systems.

Technical Context

The device implements a single-core Arm Cortex-M0+ with MPU, supporting Thumb-2 instruction set and hardware divide. Memory subsystem includes 64 KB of flash with readout protection and 8 KB SRAM with hardware parity checking - both validated for operation across –40°C to +85°C ambient.

Clock architecture combines four sources: 4–48 MHz HSE crystal oscillator, 32 kHz LSE with calibration, 16 MHz HSI RC with PLL, and 32 kHz LSI RC (±5%). Peripheral interconnect uses AHB/APB buses with DMA controller routing to ADC, timers, and communication interfaces including I2C Fast-mode Plus (1 Mbit/s) and SPI at 32 Mbit/s.

FAQ

Does STM32G030K6T6 support USB device functionality?

No. The STM32G030K6T6 does not integrate a USB PHY or USB controller. It lacks dedicated USB pins and associated registers. For USB connectivity, designers must use external USB-to-UART bridges or select higher-series parts like STM32G071 that include USB 2.0 FS device capability.

What is the maximum allowed crystal frequency for the HSE oscillator?

The HSE oscillator supports external crystals from 4 MHz to 48 MHz, as specified in Section 5.3.7 of the DS12991 Rev 6 datasheet. Operation above 48 MHz violates absolute maximum ratings and may cause startup failure or timing violation in PLL-derived clocks.

Can the internal 16 MHz RC oscillator be used as the system clock source without calibration?

Yes. The HSI16 RC oscillator operates at 16 MHz ±1% after factory trimming and can serve as the system clock without external components. Its accuracy is sufficient for UART communication up to 115.2 kbps and general-purpose timing, though crystal-based clocks are recommended for LIN or ISO7816 compliance.

Is the STM32G030K6T6 pin-compatible with STM32G030F6 in TSSOP20?

No. STM32G030K6T6 uses LQFP32 (32-pin) packaging, while STM32G030F6 uses TSSOP20 (20-pin). They share functional peripherals but differ in I/O count, pin assignment, and package dimensions - requiring separate PCB layouts and schematic symbols.
