Where to Find 28 Pin PIC Microcontroller Suppliers?

China remains a central hub for microcontroller sourcing, with key supplier clusters concentrated in Shenzhen and Guangzhou. These regions host specialized electronics manufacturers that offer scalable production of 8-bit and 16-bit PIC microcontrollers in 28-pin configurations, commonly used in embedded control systems, industrial automation, and consumer electronics. The proximity to semiconductor distribution networks and contract manufacturing services enables rapid component availability and streamlined logistics.

Suppliers in this ecosystem typically operate within vertically integrated supply chains, providing access to both new and legacy ICs. Many maintain inventories of Microchip-compatible devices such as the PIC16F and PIC18F series, often packaged in DIP-28 or SOIC-28 formats. Buyers benefit from localized technical support, flexible order volumes (from single pieces to bulk packs), and competitive pricing driven by high market density. Lead times average 7–15 days for in-stock items, with express shipping options available for urgent procurement needs.

How to Choose 28 Pin PIC Microcontroller Suppliers?

Selecting reliable suppliers requires systematic evaluation across technical, operational, and transactional dimensions:

Technical Accuracy and Product Matching
Confirm exact device compatibility—verify model numbers (e.g., PIC16F887-I/P, PIC18F44K22-I/P) against official datasheets. Ensure pin count, memory size, voltage range, and package type align with design requirements. Request PDF datasheets directly from suppliers to validate electrical characteristics and programming specifications.

Supply Chain Reliability Indicators
Assess supplier performance metrics derived from verified transaction histories:

• On-time delivery rates exceeding 95% indicate consistent logistics execution
• Response times under 6 hours reflect operational responsiveness
• Reorder rates above 25% suggest customer satisfaction and product reliability

Cross-reference listed products with original manufacturer documentation to mitigate risk of counterfeit or remarked ICs.

Order Flexibility and Risk Mitigation
Prioritize suppliers offering low minimum order quantities (MOQs), including single-piece sampling, to support prototyping and testing. Evaluate pricing transparency—stable per-unit costs across volume tiers signal authentic inventory. Use secure payment methods and request sample validation before scaling orders. For long-term projects, confirm availability of lifecycle management support and obsolescence planning.

What Are the Best 28 Pin PIC Microcontroller Suppliers?

Performance Analysis
Shenzhen-based suppliers dominate responsiveness and delivery consistency, with three achieving 100% on-time fulfillment. Shenzhen Working Technology stands out with a 33% reorder rate and customization capabilities, indicating strong buyer retention. Shenzhen Quanyuantong reports the highest online revenue, suggesting extensive export activity and inventory breadth, despite a lower reorder rate. For prototype development, Guangzhou Little Sesame offers the most flexible MOQs (down to one unit), though its slower response time may impact urgent timelines. Buyers requiring traceable original components should prioritize suppliers listing specific model variants (e.g., PIC16F873A-I/SP) and offering packaging customization.

FAQs

How to verify 28 pin PIC microcontroller supplier authenticity?

Request batch numbers, date codes, and original packaging photos. Cross-check product part numbers with Microchip’s official product matrix. Validate seller credentials through transaction verification systems and demand clear return policies for non-conforming goods.

What is the typical lead time for sample orders?

In-stock samples ship within 1–3 business days. Delivery via international courier takes 3–7 days depending on destination. Confirm stock availability prior to order placement, especially for discontinued or low-volume models.

Do suppliers provide datasheets in PDF format?

Yes, reputable suppliers can provide official PDF datasheets upon request. These documents include pinouts, timing diagrams, memory maps, and programming specifications essential for integration and compliance testing.

Can I order a single 28-pin PIC microcontroller for testing?

Multiple suppliers offer single-unit pricing, particularly those listing “1 piece” as minimum order. This supports low-risk evaluation and firmware development before committing to volume purchases.

Are there risks associated with low-cost microcontroller suppliers?

Potential risks include remarked, recycled, or counterfeit ICs sold as new. Mitigate through supplier due diligence: review transaction history, demand origin documentation, test initial batches for performance consistency, and use optical inspection for package anomalies.
