Sound familiar in procurement?
- Industrial DRAM and flash markets shift fast—sharp price moves, tight allocation, and quotes that lack a firm delivery window when your build is already scheduled
- DRAM and flash split across unrelated suppliers—no single engineering owner when a line fails in the field
- Products marked as “industrial grade” but with limited temperature tolerance—cold outdoor starts and hot sealed cabinets both expose the gap
- Suppliers who won’t quote small quantities or only serve large programs when you need a few pieces to prove fit
- Fit or quality questions need pinout, footprint, and alternative-part support from engineers who own the program—not just a quote with no technical contact
How we solve it—try before you scale
- Free first step — email BOM or inquiry; we reply with PDF datasheet and quotation on your thread
- Confirm price & fit — remote review of drawings, memory map, and incumbent part match so you can use it—and use it well on your board; pilot and production quantities welcome—very low MOQ quoted per line
- Sample & validate — buy samples only if the quote works for you; test on your hardware before bulk commitment
- Bulk with capacity — typical production lead 4–8 weeks (working days) from Ningbo when you are ready
We reply on your inquiry thread only—no spam, no cold calls; project updates if you ask for them. Large or small, every customer gets the same care: sincere service creates value for you and for us—we grow when your program succeeds.

The Hidden Cost of Unqualified Memory
In enclosures that swing cold and hot, one memory failure often costs more than a year of chip spend. Today’s industrial DRAM and flash market adds another risk: volatile pricing, tight allocation, and uncertain delivery commitments while your production window is fixed. For solder-down DRAM and flash, the advantage is Industrial WT (−40~85°C) and Industrial Ext (−55~105°C) grades screened in Xi’an, controlled quality, long service life, and stable operation at both ends of the range. Expand for common field risks and how we address them.
Show field risks & Loongtion responses
| What goes wrong in the field | How Loongtion addresses it |
|---|---|
| Consumer or desk-temp parts that drift, fail early, or cannot sustain years of industrial duty in cold or hot enclosures | Incoming QC and release test in Xi’an; Industrial WT and Industrial Ext screening per JEDEC rules; on qualified bulk programs, 5-year free replacement under normal operating conditions (non-human damage)—see warranty scope |
| Industrial DRAM/flash in a volatile cycle—prices and allocation shift quickly; firm ship dates are hard to lock while your build slot is fixed | We program and stock these industrial lines; typical bulk lead 4–8 weeks (working days) from Ningbo when you order. Quotation valid 7 days—pricing tracks current market supply; we quote fairly to current conditions, not speculative spikes |
| Enclosure runs too cold (outdoor winter, cold start) or too hot (sealed cabinet, sun load) but DRAM/flash rated for a narrower range only | Industrial WT (−40~85°C) and Industrial Ext (−55~105°C) grades per family where listed; temperature-dependent refresh and screening per JEDEC design rules |
| Wrong organization (×8 vs ×16) or package on the BOM | Orderable PN tables above; engineering reviews controller memory map and footprint by email before you commit |
| DRAM and flash from unrelated suppliers with no shared engineering contact | One Loongtion program covering DDR3/4/5, LPDDR4X, eMMC, and NVMe BGA—one contract entity, unified project engineering on your inquiry thread |
| Procurement needs PDF spec and clear commercial terms before approval | Datasheet PDF + quotation per commercial terms—usually within 24h on Mon–Fri UTC+8 |

Frequently Asked Questions
Answers for procurement and design-in engineers on our industrial memory chip program—including Industrial WT / Industrial Ext grade selection.
Getting started
How do I get the datasheet and quote?
Email or the inquiry form below. We usually reply within 24h (Mon–Fri UTC+8) with PDF datasheet, quotation, and engineering notes.
Which product line should I start with?
Match your controller and BOM: DDR3 for legacy platforms, DDR4/DDR5 for standard SDRAM interfaces, LPDDR4X for low-power SoC and mobile industrial terminals, eMMC for solder-down flash, NVMe BGA for compact PCIe storage on the PCB. Send your BOM—our engineering team will recommend the right family and part number by email.
How does engineering support work?
Remote only on your email inquiry thread—no routine on-site visits. We review drawings, memory maps, incumbent parts, pinout, and footprint so you can use it—and use it well on your hardware. Engineering support runs from Ningbo (sales/contracts) and Xi’an (R&D/QA)—same program. We respond on China business days (Monday–Friday UTC+8), excluding Chinese statutory holidays. We usually reply within 24 hours on those days with PDF datasheet and quotation.
Product & compliance
What standards and certificates apply?
GB/T 19001-2016 / ISO 9001:2015 (quality system), business registration, trademarks, patents, and high-tech enterprise credentials are shown in the documentation gallery. Design compliance: JEDEC DRAM (e.g. JESD79-3F DDR3, JESD79-4 DDR4, JESD79-5 DDR5) and eMMC 5.1 (JESD84-B51.1); lead-free, RoHS-aligned. Full AC timing and MSL are in the product PDF.
China-domestic supply documentation: selected lines (DDR3, DDR5, LPDDR4X) can support programs that require verified China-domestic supply and certification documents—not required for most global export programs; ask sales if your AVL needs it.
Are these chips for military or defense use?
No. We do not market these devices for military or defense end-use. Industrial WT and Industrial Ext grades reflect harsh industrial qualification—cold outdoor telecom, oil & gas edge, hot cabinet infrastructure—not armed-forces programs.
Design-in & specifications
What MSL (moisture sensitivity) level applies?
MSL grade is listed on each product datasheet (typically MSL 3 for DRAM/LPDDR4X). Follow J-STD-033 bake and floor-life rules for production. Email engineering if your EMS needs the handling note for a specific part number.
Are different capacities pin-compatible on the same package?
DDR3 2Gb/4Gb/8Gb on FBGA96 ×16 share the same ball map. DDR4 FBGA78 (×8) and FBGA96 (×16) are different packages—not interchangeable; each listed chip is an 8Gb die (1GB byte capacity). DDR5 is 16Gb per chip (2GB byte capacity). Confirm organization and footprint from the datasheet PDF or by email before AVL lock.
How are temperature ratings defined?
Published −40~85°C (Industrial WT) and −55~105°C (Industrial Ext) ranges are case temperature (Tc) ratings for the stated speed bins under JEDEC operating rules—covering both low-temperature cold starts and high-temperature sealed-cabinet duty where those grades are orderable. Your enclosure thermal model and airflow still matter—share thermal data by email for grade selection. Orderable temp ranges are in the PN tables above and the product PDF (not “confirm later” placeholders).
Where are eMMC endurance and performance numbers?
pSLC vs TLC PE cycles, sequential read/write, and features such as Boot/RPMB are documented in the product datasheet PDF—not on this summary page. Request the datasheet for your capacity and flash type.
Supply chain & compliance
What is your PCN / EOL policy?
Product change notices (PCN) for material or process changes are issued in writing—typically 90 days before implementation. Planned end-of-life (EOL) is typically communicated 12 months in advance with last-buy opportunities where applicable. Full terms are on your commercial quotation.
How are parts packaged for shipment?
DDR/LPDDR4X are typically shipped in industrial trays; eMMC may be tray or tape-and-reel depending on part number. All units ship in ESD moisture-barrier packaging. Minimum pack quantities (MPQ) are stated on the quote.
Contact & privacy
What happens after I submit the inquiry form?
We email what you requested—PDF datasheet and quotation for your line—and answer technical questions on that thread. Ask in your email if you want ongoing project updates.
How do you protect my privacy?
We take customer privacy seriously. Your contact details and project information stay with Loongtion only—we never sell or share them with third parties. No spam emails, no unsolicited sales calls—only replies related to your inquiry on your email thread.
Commercial & warranty
What is your minimum order quantity (MOQ)?
Very low MOQ—quoted per product line, not one number for everything. Many lines can ship from 1 piece when we have stock; production MOQ depends on grade, package, and your quantity. Tell us what you need in your inquiry or message—we don’t turn away small pilot orders.
What are your commercial terms?
See Commercial terms: low MOQ per line (often from 1 pc when stocked), T/T 50% + 50%, ship from Ningbo, China, bulk lead 4–8 weeks (working days), quotation valid 7 days.
What warranty applies to bulk orders?
