Read MoreHow to Read MCU Part Numbers
MCU part numbers are not random codes. They usually show the manufacturer series, product family, pin count, memory size, package type, and temperature grade. For engineers and sourcing teams, reading the full part number correctly is important before PCB design, replacement selection, or mass production.
Example: STM32F103C8T6
| Code | Meaning |
|---|---|
| STM32 | STMicroelectronics 32-bit MCU series |
| F103 | Product family and performance series |
| C | Pin count code |
| 8 | Flash memory size code |
| T | Package type |
| 6 | Temperature grade |
Example: ATMEGA328P-AU
| Code | Meaning |
|---|---|
| ATMEGA | AVR MCU series |
| 328P | Specific model and performance grade |
| AU | Package and ordering code |
Selection Note:
When selecting a microcontroller, small differences in package code, memory size, temperature grade, or ordering suffix may affect PCB compatibility, firmware compatibility, and production reliability.
Microcontroller MCU FAQ Guide
MCU sourcing requires careful checking because small differences in part number, package, memory size, temperature grade, or ordering suffix may affect product compatibility.
We help customers reduce sourcing risk by confirming part numbers, checking stock, verifying package information, reviewing supplier channels, and supporting possible alternative model matching. Whether you need samples, small batch supply, urgent stock, or long-term sourcing support, we can provide flexible MCU supply solutions based on your project needs.
We follow a basic quality inspection process before shipment. This includes checking the part number, brand, package type, quantity, label information, date code, and batch details.
We also inspect the appearance of the MCU components, including chip marking, pin condition, package surface, oxidation, scratches, damage, and packaging condition. For moisture-sensitive parts or high-value models, we can also check the packaging status and arrange additional inspection support if required.
We can help source common MCU packages such as LQFP, TQFP, QFN, BGA, SOP, SSOP, TSSOP, DIP, and WLCSP. Package confirmation is important before ordering.
Yes. For some projects, we can support MCU programming, firmware pre-loading, labeling, and basic functional testing if customers provide firmware files and test requirements.
Yes. Sample orders are available for many MCU models. We recommend sample testing before mass production to confirm PCB compatibility, firmware operation, and system stability.
Delivery time depends on whether the MCU components are in stock or need to be ordered.
Lead time is not assumed from this category page. It must be confirmed for the exact manufacturer part number, quantity, package, date-code requirement, supplier source and delivery destination during RFQ review.
For hard-to-find, discontinued, automotive-grade, or high-demand MCU models, the lead time may be longer, usually around 2–6 weeks. Before you place the order, we will confirm the estimated delivery date and shipping method based on your required MCU part number and quantity.
MOQ depends on the specific MCU model, package, stock status, and supplier channel. For common in-stock parts, sample quantities or small batch orders may be available.
Yes. If the original MCU is out of stock or has a long lead time, we can help check possible alternatives based on package, pin count, memory size, voltage, interfaces, and application requirements.
Yes. You can send us the MCU part number or BOM list, and we will help check stock, confirm package type, verify brand information, and provide suitable sourcing options.
We are an electronic components supplier and sourcing partner, not the original MCU manufacturer. We help customers source original and traceable microcontroller components for industrial, automotive, IoT, consumer, and embedded applications.
