STM32G050C8T6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
MPN： STM32G050C8T6 ✓ 啟用中STM32G050C8T6 概覽
A microcontroller is a programmable system-on-chip that combines a processor core, nonvolatile program memory, volatile data memory, peripherals, and I/O in one package. Within the embedded-control hierarchy, the STM32G050 belongs to the Arm Cortex-M0+ MCU, 32-bit microcontroller, embedded processor, and semiconductor product classes. This structure allows one component to execute control software and supervise sensors, communications, timers, and analog signals without a separate processor.
The principal specifications are a 64 MHz Arm Cortex-M0+ core, 64 KB Flash, 18 KB SRAM, and a maximum 64 MHz operating frequency. The device is described as a Mainstream Value Line product with two USARTs, timers, an ADC, communication interfaces, and LIN connectivity. Its 48-LQFP package provides 48 externally accessible pins in a 7 x 7 mm surface-mount format suitable for compact control boards.
The STM32G050C8T6 architecture targets cost-sensitive embedded nodes where a compact Cortex-M0+ core, useful memory capacity, and common serial interfaces are more important than a high-pin-count package or advanced connectivity. ST identifies the STM32G050x6 and STM32G050x8 devices as mainstream microcontrollers based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating up to 64 MHz. The C8 designation in the offered configuration corresponds to the verified 64 KB Flash and 18 KB RAM configuration presented by the manufacturer and distributors.
Typical uses include LIN-connected industrial and building-control nodes, compact sensor interfaces, power and motor supervisory controllers, communication bridges, low-cost USB-connected configuration tools, and general embedded-control products. Two USART channels support serial links, the ADC supports analog measurement, and the timer resources suit periodic control tasks. Firmware must still be reviewed against the complete datasheet before assigning every peripheral or pin.
Designers should confirm the exact pin multiplexing, electrical limits, clock tree, ADC characteristics, and low-power behavior from the official STM32G050C8 documentation. Decoupling requirements, exposed-ground layout, programming access, and oscillator stability are as important as the nominal 64 MHz CPU rating when establishing reliable operation.
This product record consolidates current manufacturer and distributor information, verified pricing availability references, package details, and practical substitution guidance. It also distinguishes confirmed drop-in candidates from parts that require board, firmware, and peripheral-level review, adding engineering context beyond a basic distributor listing.

典型應用
STM32G050C8T6 適用於 6 應用s: LIN-Connected Automotive and Building Nodes, Industrial Sensor and Signal Acquisition, Power-Supply Supervision, Serial Communication Bridge, Low-Cost USB Configuration and Test Adapter, Compact Embedded Control Module.
LIN-Connected Automotive and Building Nodes
The STM32G050C8T6 fits compact LIN nodes because the verified feature set includes LIN connectivity, two USARTs, timers, an ADC, and a 64 MHz Arm Cortex-M0+ core. It can execute protocol handling, supervisory logic, and periodic control tasks within 64 KB of Flash and 18 KB of RAM. The 48-LQFP 7 x 7 mm package preserves access to 48 pins for power, communications, analog inputs, and discrete I/O. A LIN transceiver and connector remain external, and the exact protocol, timing, and electrical requirements must be validated against the complete manufacturer documentation.
推薦
Industrial Sensor and Signal Acquisition
The STM32G050C8T6 is suitable for small industrial sensing modules that require local analog measurement and deterministic control without a high-performance application processor. Its verified 64 MHz Cortex-M0+ core provides processing capacity, while the ADC, timers, and 64 KB Flash support acquisition, filtering, thresholding, and supervisory firmware. The 18 KB RAM can hold working buffers, and two USARTs permit configuration or data exchange with a host. The 48-LQFP package provides a practical pin count, although industrial temperature limits, EMC performance, and calibration requirements are not specified in the verified data.
推薦
Power-Supply Supervision
The STM32G050C8T6 can supervise a compact power-management subsystem by combining its 64 MHz control core, ADC, timers, and communication interfaces. Verified capabilities support voltage measurement, threshold logic, periodic updates, and host reporting, while the 64 KB Flash and 18 KB RAM are adequate for a focused supervisory application rather than a complex control workload. The 48-LQFP package allows separate assignments for analog inputs, status indicators, communications, and power rails. Exact ADC resolution, accuracy, conversion rate, and absolute-pin limits must be taken from the official datasheet before setting protection thresholds.
推薦
Serial Communication Bridge
The STM32G050C8T6 is appropriate for a compact protocol-conversion node because it provides two USARTs, communication interfaces, timers, and a 64 MHz Cortex-M0+ core. Firmware can receive data on one serial channel, validate or translate it, and forward it through the other while timers manage timeouts or periodic transfers. The 64 KB Flash and 18 KB RAM provide useful capacity for a focused bridge application. Pin multiplexing, baud-rate support, interface electrical characteristics, and protocol-specific behavior are not included in the verified summaries and must be checked before implementation.
推薦
Low-Cost USB Configuration and Test Adapter
The STM32G050C8T6 can serve as the controller in a compact configuration or test adapter where a 64 MHz Cortex-M0+ core, 18 KB RAM, and 64 KB Flash are sufficient for protocol handling and diagnostics. Its timers and USART resources can support measurement intervals, logging, and device communication, while the 48-LQFP package offers more routing flexibility than a minimal package. USB electrical compliance, supported USB classes, crystal requirements, and exact USB peripheral resources are not confirmed in the supplied snippets, so this use requires full feature verification.
推薦
Compact Embedded Control Module
The STM32G050C8T6 is well matched to compact embedded-control modules that combine a processor, timers, ADC, and serial communications in one PCB footprint. Its 64 MHz Cortex-M0+ core executes control logic efficiently, while 64 KB Flash and 18 KB RAM cover focused firmware and data-buffer requirements. The 48-LQFP 7 x 7 mm package provides 48 pins for power, sensors, actuators, debug, and communications without moving to a large fine-pitch package. Its verified 2 V to 3.6 V range supports low-voltage embedded systems, subject to exact I/O and peripheral operating limits.

設計說明
The verified operating range is 2 V to 3.6 V, with 3.3 V identified as a common nominal condition. Place the required supply capacitors at the corresponding VDD and VSS pins, maintain short return paths, and separate analog or communications supply filtering from noisy digital switching nodes. Before selecting component tolerances, confirm the actual VDD-to-VSS limits, internal-regulator behavior, startup timing, and maximum GPIO current from the complete manufacturer datasheet.
Use the manufacturer's 48-LQFP land pattern and preserve access to all power, ground, reset, boot, debug, and programming pins. A 7 x 7 mm package has only 0.5 mm lead pitch, so inspect solder-paste volume, pad geometry, and assembly capability before release. Route sensitive analog inputs away from switching nodes and maintain a continuous ground reference beneath and around the device where the recommended layout permits.
Do not treat a matching 48-LQFP footprint as proof of drop-in equivalence. Firmware startup code, vector tables, GPIO alternate functions, UART assignments, ADC channels, timer resources, clock settings, and low-power modes can differ among STM32G0 and STM32F0 variants. For every proposed alternative, compare the official datasheets and perform boot, interrupt, communication, analog, timing, and brownout testing on representative hardware.
Keep the 64 MHz clock circuit and decoupling layout as short as practical, and follow the manufacturer guidance for oscillator and startup components. Place the MCU's supporting crystals, load capacitors, programming-header contacts, and test points according to the reference layout. Validate signal integrity with the final PCB stack-up and enclosure because LQFP pad parasitics, return-current discontinuities, and adjacent high-speed nets can affect reliable clocking and communications.
The MCU is intended for compact embedded systems that may also contain switching regulators, relays, and communications transceivers. Keep switching-node copper away from ADC inputs, oscillator circuitry, and serial interfaces, and use the application guidance for filtering and grounding. The supplied data does not specify EMC immunity, emission limits, or conducted-noise performance, so compliance must be established through the complete product standard and testing process rather than assumed from the MCU family name.
合規資訊
The supplied manufacturer and distributor snippets do not state the target part's compliance status. These fields remain unknown rather than being inherited from the broader STM32 family.
