Where to Find AT28C64 Memory Chip Suppliers?
China remains a central hub for legacy and specialized semiconductor sourcing, with Shenzhen and Shantou emerging as key centers for memory chip distribution. These regions host dense electronics supply ecosystems, offering access to both original and compatible components for industrial, automotive, and embedded system applications. The AT28C64, a 64 Kbit EEPROM commonly used in legacy control systems and firmware storage modules, is actively traded through specialized IC distributors leveraging established logistics networks and component verification protocols.
Suppliers in this sector operate within vertically integrated procurement channels, often combining direct manufacturer partnerships with aftermarket inventory management. This structure enables rapid order fulfillment—typically within 1–7 days for sample quantities—and scalable supply for medium-volume production runs. Buyers benefit from localized technical support, standardized packaging options, and flexible shipping arrangements across global markets. Cost efficiencies stem from competitive pricing models, with unit prices ranging from $0.01 to $7.43 depending on package type, condition (new/original vs. compatible), and order volume.
How to Choose AT28C64 Memory Chip Suppliers?
Effective supplier selection requires adherence to structured evaluation criteria focused on authenticity, transaction reliability, and operational responsiveness:
Component Authenticity & Traceability
Verify whether the supplier stocks original Atmel (Microchip) parts or offers functionally equivalent alternatives. Demand batch traceability data and visual inspection reports for high-volume orders. Be cautious of listings priced significantly below market average (e.g., <$0.10/unit), which may indicate recycled or remarked components.
Quality Assurance Metrics
Prioritize suppliers demonstrating consistent performance through measurable indicators:
- On-time delivery rates exceeding 95%
- Response times under 4 hours
- Reorder rates above 20% indicating customer retention
- Documented testing procedures for electrical parameters (access time, write endurance, data retention)
Order Flexibility and Scalability
Assess minimum order quantity (MOQ) structures and tiered pricing models. Several suppliers offer single-piece sampling at premiums ($1.50–$5.85), while bulk purchases (200+ units) unlock lower per-unit costs. Confirm availability across common packages: DIP-28, PLCC-32, and TSSOP-28. For integration into automated assembly lines, ensure tape-and-reel or tray packaging compatibility.
What Are the Best AT28C64 Memory Chip Suppliers?
| Company Name | Main Products (Listings) | Online Revenue | On-Time Delivery | Response Time | Reorder Rate | Min. Order Flexibility | Price Range (Unit) |
|---|---|---|---|---|---|---|---|
| Shenzhen Dang Jie Technology Co., Ltd. | Other ICs (7,700) | US $20,000+ | 96% | ≤1h | <15% | 1 piece | $1.50–$5.85 |
| Shantou Xinjing Microelectronics Co., Ltd. | Microcontrollers and Processors, FPGA (33,899) | US $50,000+ | 97% | ≤4h | 20% | 1 piece | $0.20–$4.70 |
| Shenzhen Cxcw Electronic Co., Ltd. | Customization Services | US $100,000+ | 95% | ≤3h | 23% | 10 pieces | $0.01–$3.00 |
| Shenzhen Chuangyun Xinyuan Technology Co., Ltd | Other ICs (604,507) | US $80,000+ | 100% | ≤5h | 57% | 234+ pieces | $1.75–$8.28 |
| Shenzhen Xinqiwei Technology Co., Ltd. | Other ICs (250,517) | US $1,000+ | 100% | ≤1h | <15% | 112+ pieces | $1.75–$14.86 |
Performance Analysis
Shantou Xinjing and Shenzhen Cxcw stand out for low MOQs and competitive pricing, making them suitable for prototyping and small-batch replacements. Shenzhen Chuangyun Xinyuan demonstrates exceptional reliability with a 100% on-time delivery rate and high reorder frequency, indicating strong post-sale satisfaction despite higher volume requirements. Shenzhen Dang Jie and Xinqiwei offer fast response times (≤1h), beneficial for urgent procurement cycles. However, Xinqiwei’s higher price range suggests a focus on premium or verified-original stock. Suppliers with diversified IC portfolios (e.g., over 30,000 listings) typically maintain broader inventory depth, reducing lead time risks for cross-component projects.
FAQs
How to verify AT28C64 memory chip authenticity?
Request high-resolution images of laser markings, batch codes, and packaging seals. Cross-reference part numbers (e.g., AT28C64B-20JI vs. AT28C64E-15PC) with official Microchip datasheets. For critical applications, conduct electrical testing using standard protocols for read/write cycle validation and data retention checks.
What is the typical lead time for AT28C64 shipments?
In-stock units ship within 1–3 business days. International delivery via express courier takes 3–7 days. Bulk orders requiring sourcing coordination may extend lead times to 10–15 days, especially if binning or tape/reel preparation is needed.
Can suppliers provide RoHS-compliant or industrial-grade variants?
Yes, many suppliers list temperature-rated versions (e.g., -40°C to +85°C) and lead-free/RoHS-compliant packages. Confirm compliance through product specifications or request material declaration sheets prior to ordering.
Is customization available for labeling or packaging?
Selected suppliers, such as Shenzhen Cxcw Electronic, offer customization services including branded labeling, anti-static packaging, and color-coded sorting. Minimum volumes apply, typically starting at 1,000 units.
What are standard payment terms for first-time buyers?
Most suppliers accept secure digital payments with escrow protection. Letters of Credit (L/C) are uncommon for sub-$1,000 orders. New buyers should start with small test purchases to evaluate component quality and shipment accuracy before scaling procurement.
