Longsys FORESEE Industrial DDR4 DIMM — -40 to 85 C SODIMM and UDIMM, 4 GB to 32 GB

Specifications

Overview

Longsys FORESEE industrial DDR4 modules are DDR4-3200 parts with CL22 timing at 1.2 V, offered as SODIMMs (69.60 x 30.00 mm) and UDIMMs (133.35 x 31.25 mm) in 4 GB, 8 GB, 16 GB and 32 GB densities across 1R x 16, 1R x 8 and 2R x 8 organisations. The three-letter suffix identifies the temperature bin: F4SNW for -40 C to +85 C, F4SNM for -25 C to +85 C and F4SNS for 0 C to +85 C.

ECC variants are carried under the F4SE family for applications where single-bit correction in the memory path matters — machine-vision controllers, medical instruments and edge servers operating outside temperature-controlled rooms. Non-ECC parts cover mainstream industrial PCs and HMIs.

The modules are produced at Longsys' Zhongshan Storage Industrial Park and are characterised for stability in extreme environments, with 30 micro-inch gold plating on the edge connectors, a complete retention cycle for core customer-procured materials, and vendor-published Intel and AMD platform compatibility lists.

For designers upgrading existing industrial platforms that still carry DDR4 SODIMM or UDIMM slots, wide-temperature FORESEE modules let a validated board run in outdoor cabinets, vehicles and unheated factory floors without changing memory architecture.

Key Benefits

-40 C to +85 C options in DDR4 SODIMM and UDIMM form factors. ECC and non-ECC variants in the same family. Up to 32 GB at 3200 Mbps, CL22. 30 micro-inch gold edge connectors for repeated insertion cycles. Intel and AMD platform validation published by the vendor.

Applications

Industrial PCs, HMIs and panel computers in unheated environments; outdoor telecom and energy cabinets; in-vehicle and railway computing; machine-vision controllers needing ECC; medical and analytical instruments; legacy industrial platform refreshes.
