STM32G050K8T6 - 64MHz Arm Cortex-M0+ 64KB MCU | STMicroelectronics
MPN: STM32G050K8T6 ✓ ActiveSTM32G050K8T6 Overview
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and interface circuitry into one package. The STM32G050K8T6 uses an Arm Cortex-M0+ RISC core, a simplified 32-bit architecture intended for efficient embedded control. Within the STM32 family hierarchy, this device belongs to the STM32G0 mainstream value line, combining general-purpose processing with communication interfaces, timers, and an ADC.
Verified device characteristics include a maximum CPU frequency of 64 MHz, 64 KB of Flash memory, 18 KB of RAM, and two USART interfaces. Its operating voltage range is 2 V to 3.6 V. These attributes make it suitable for small control systems that need serial connectivity, periodic timing functions, and analog measurement without requiring a larger high-density MCU.
The STM32G050K8T6 combines 64 KB of nonvolatile program storage with 18 KB of SRAM, providing enough space for firmware, configuration data, and moderate working buffers. Its 64 MHz Cortex-M0+ core supports deterministic control tasks, while the listed USART interfaces allow connection to sensors, actuators, human-interface modules, or industrial communication equipment. The integrated ADC expands its usefulness in metering, monitoring, and embedded automation applications.
Typical uses include IoT sensor nodes, compact motor-control and metering boards, industrial automation controllers, and low-power embedded products. The 32-LQFP 7 x 7 mm package provides a widely used footprint with exposed leads that are inspectable during visual assembly and suitable for prototypes as well as moderate-volume production.
When designing a board around the STM32G050K8T6, verify every signal assignment against the manufacturer's package pinout and power recommendations before layout release. The 2 V to 3.6 V supply range and 64 MHz performance must be considered together when selecting regulators, decoupling, clock components, and trace geometry. Firmware migration decisions should also account for peripheral availability and the memory-map differences of substitute MCUs.
This page consolidates verified manufacturer and distributor information, price context, application guidance, and a same-package replacement analysis. It also distinguishes confirmed device facts from parameters that require confirmation from the full manufacturer datasheet, helping engineers evaluate fit without mistaking family similarity for guaranteed drop-in equivalence.

Typical Applications
STM32G050K8T6 is suitable for 6 applications: Compact IoT Sensor Nodes, Industrial Metering and Monitoring, Embedded Automation Controllers, Low-Power Smart Sensor Boards, Human-Machine Interfaces and Serial Consoles, Basic Motor and Actuator Control.
Compact IoT Sensor Nodes
The STM32G050K8T6 fits compact IoT sensor nodes because its 64 MHz Arm Cortex-M0+ core, 64 KB of Flash, and 18 KB of SRAM can hold protocol handling, sampling logic, and local buffering in one device. Two USART interfaces allow connection to external sensors or a wireless module without immediately consuming all available resources. Its 2 V to 3.6 V operating range also supports low-voltage rail designs. The tradeoff is that a 64 KB program region limits firmware growth, so OTA rollback slots and protocol expansion must be considered during partitioning.
Recommended
Industrial Metering and Monitoring
For metering and condition-monitoring boards, the STM32G050K8T6 combines 64 KB of Flash for acquisition and calibration routines with 18 KB of RAM for working buffers. The integrated ADC supports analog measurement, while the timers and two USARTs can organize periodic sampling and communicate with local displays or upstream controllers. At up to 64 MHz, the Cortex-M0+ core also provides useful control headroom. Engineers should confirm ADC accuracy, channel count, reference requirements, and analog-pin assignment in the full datasheet before committing the board layout.
Recommended
Embedded Automation Controllers
The STM32G050K8T6 is suitable for small embedded automation controllers that coordinate discrete sensors and actuators. Its timers support periodic control tasks, its ADC handles analog process inputs, and its two USARTs permit local service or configuration links. The 32-LQFP 7 x 7 mm package keeps the controller compact without relying on a very fine-pitch BGA footprint. Firmware partitioning is important because 64 KB of Flash can be quickly consumed by communication stacks, safety checks, and field-upgrade logic, so production images should be measured early.
Recommended
Low-Power Smart Sensor Boards
A smart sensor board can use the STM32G050K8T6 as a low-power control hub when the workload includes local filtering and serial reporting rather than high-volume graphics or wireless protocol processing. The 18 KB of RAM supports bounded sample buffers, and the 64 KB of Flash accommodates configuration tables and device firmware. The two USART interfaces are useful for pairing with a sensor front end and a host interface. Actual sleep-mode behavior, wake sources, and peripheral clock availability require confirmation from the manufacturer documentation because they are not included in the verified listing summaries.
Recommended
Human-Machine Interfaces and Serial Consoles
The STM32G050K8T6 can manage compact human-machine interfaces built around serial displays, keypads, and configuration ports. Two USARTs allow a console to coexist with a downstream controller, while the timers help organize keypad scanning, indicator updates, and communication timeouts. Its 18 KB of RAM is adequate for modest text buffers and short data frames rather than graphics rendering. The principal limitation is firmware capacity: adding menu logic, multilingual resources, and bootloader code can push a 64 KB image, making linker-map review an essential design check.
Recommended
Basic Motor and Actuator Control
The STM32G050K8T6 can serve as the logic controller in cost-sensitive motor or actuator designs where a 64 MHz Cortex-M0+ core, timers, ADC, and two USARTs are sufficient. Timers can generate deterministic control intervals, the ADC can monitor current or position-related analog signals, and serial communication can support parameter configuration. The value-line MCU offers useful processing headroom without moving to a larger pin count. Actual motor-drive timing, PWM resolution, and fault-handling behavior must be checked against the complete peripheral documentation and the selected power stage.

- 18 KB RAM supports moderate local buffering (vs STM32G050K8T7)
Design Notes
Design the supply for the verified 2 V to 3.6 V operating range rather than treating 3.3 V as an exact requirement. Place the regulator's high-frequency decoupling close to the MCU supply pins, and confirm which supply pins belong to digital, analog, and core domains from the official pin table. Analog measurements require particular attention because an ADC supply or reference decision made without the full datasheet can degrade readings even when the MCU runs correctly.
Use a 32-LQFP 7 x 7 mm land pattern and follow the manufacturer's package drawing and recommended footprint exactly. Route sensitive analog inputs away from switching nodes, serial edges, and clock lines, while keeping the analog ground connection strategy consistent with the reference design. Because the verified search excerpts do not provide the complete pin table, do not assign pins or vias solely from an online placement diagram without cross-checking the official datasheet.
The 64 KB Flash limit can be overlooked during early firmware planning. Measure the linked image while communications stacks, bootloaders, and application logic are still growing, and avoid reserving storage for an OTA rollback scheme that cannot fit. For any proposed replacement, verify the peripheral set, interrupt behavior, clock tree, and flash organization; a matching package and CPU family do not by themselves guarantee unchanged application behavior.
Compliance Information
The supplied verified search results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values must be confirmed from the current manufacturer product documentation and declaration before regulatory release.
