About atmega 328
Where to Find ATmega 328 Microcontroller Suppliers?
China remains a central hub for semiconductor and electronic component manufacturing, with Shenzhen emerging as the primary sourcing region for microcontrollers like the ATmega 328. The city's dense ecosystem of IC distributors and trading firms enables rapid access to both standalone chips and integrated development modules. Suppliers in this cluster specialize in AVR-based microcontrollers used in Arduino-compatible platforms, industrial control systems, and embedded IoT devices.
The Shenzhen supply chain benefits from proximity to major logistics ports and integration with downstream PCB assembly services, allowing for efficient order fulfillment. Most suppliers maintain inventory of common variants such as the ATmega328P-PU (DIP28) and ATmega328P-AU (TQFP32), supporting low-volume prototyping and mid-range production runs. Buyers can expect lead times of 7–15 days for in-stock items, with air freight enabling global delivery within 3–7 business days. Economies of scale are evident in bulk pricing structures, where unit costs decrease significantly at quantities exceeding 50 pieces.
How to Choose ATmega 328 Microcontroller Suppliers?
Selecting reliable partners requires due diligence across technical, operational, and transactional dimensions:
Component Authenticity & Quality Assurance
Verify that suppliers specify "original" or "genuine" ICs in product listings, particularly for Atmel/Microchip-branded components. Request batch numbers or date codes where available. While formal certifications like ISO 9001 are not universally listed, consistent on-time delivery performance (≥98%) and response times ≤2 hours indicate operational reliability.
Supply Chain Transparency
Assess supplier stability through key indicators:
- Minimum reorder rates above 20% suggest customer satisfaction and product consistency
- Online revenue exceeding US $100,000+ reflects established market presence
- Inventory depth across multiple package types (DIP, TQFP, SMD) indicates diversified sourcing channels
Cross-reference product keywords and descriptions to confirm genuine microcontroller listings versus development board mislabeling.
Procurement Safeguards
Utilize secure payment methods with dispute resolution mechanisms. Conduct sample testing to validate electrical specifications, clock frequency tolerance, and flash memory integrity before scaling orders. For high-volume purchases, request JEDEC-compliant packaging standards and moisture sensitivity level (MSL) ratings, especially for surface-mount variants.
What Are the Best ATmega 328 Microcontroller Suppliers?
| Company Name | Location | Main Products (Listings) | Online Revenue | On-Time Delivery | Avg. Response | Reorder Rate | Min. Order | Price Range (USD) |
|---|---|---|---|---|---|---|---|---|
| Shenzhen Chuangheying Electronic Technology Co., Ltd. | Shenzhen, CN | Other ICs (23,125) | US $1,300,000+ | 100.0% | ≤6h | <15% | 1 piece | $0.13–2.88 |
| Shenzhen Maoxing Weiye Technology Co., Ltd. | Shenzhen, CN | Customization Available | US $160,000+ | 100.0% | ≤2h | 21% | 1 piece | $0.42–2.88 |
| Shenzhen Mixinwei Trading Co., Ltd. | Shenzhen, CN | Microcontrollers & FPGA (4,104) | US $80,000+ | 100.0% | ≤2h | 37% | 5 pieces | $0.10–1.20 |
| ShenZhen Nova Semiconductor Co., Ltd | Shenzhen, CN | Stable Supply Chain | US $110,000+ | 98.0% | ≤2h | 22% | 1 piece | $0.91–1.58 |
| Shenzhen Jeking Electronic Corp. | Shenzhen, CN | Customization Options | US $320,000+ | 100.0% | ≤2h | 35% | 2 pieces | $1.01–2.89 |
Performance Analysis
Shenzhen Chuangheying leads in sales volume and offers one of the lowest price points ($0.13/unit), though its sub-15% reorder rate may indicate limited repeat demand. In contrast, Shenzhen Mixinwei achieves a high 37% reorder rate, suggesting strong customer retention despite higher minimum order thresholds. All top-tier suppliers maintain ≤2-hour average response times and 100% on-time delivery except ShenZhen Nova Semiconductor, which reports 98%. Pricing varies significantly based on package type and authenticity verification—SMD versions (e.g., TQFP32) command premiums up to $2.88/unit. Buyers seeking cost efficiency should prioritize suppliers offering original ATmega328P-AU chips at volumes over 50 units.
FAQs
How to verify ATmega 328 microcontroller authenticity?
Request clear images of marking codes, compare against official Microchip datasheets, and verify consistent lot numbering. Prefer suppliers who explicitly state “original” or “genuine” and avoid vague terms like “compatible” unless second-source qualification is acceptable.
What is the typical MOQ for ATmega 328 ICs?
Most suppliers offer 1-piece sampling, but discounted pricing applies at 5–50 piece increments. Bulk orders (500+) often unlock additional negotiation leverage, especially for DIP or tape-and-reel packaging formats.
Are customization options available for microcontroller orders?
Yes, select suppliers provide programming, labeling, or packaging modifications. Confirm pre-programming capabilities (e.g., bootloader loading) and tooling compatibility prior to order placement.
Do suppliers support global shipping?
All listed suppliers ship internationally via standard courier services. Confirm incoterms (e.g., FOB Shenzhen, EXW) and account for import duties on electronic components, which vary by destination country.
Can I request samples before placing a full order?
Sample procurement is widely supported, typically priced between $0.10–$2.88 per unit depending on variant. Expect delivery within 3–7 days via express carriers. Some suppliers apply sample fees toward future bulk purchases.
