SM2264 Visão geral
A PCIe NVMe SSD controller is the semiconductor platform that coordinates the host PCIe interface, NAND interface, firmware, error correction, and storage-management functions in a solid-state drive. In the hierarchy of semiconductor devices, the SM2264 is an interface and storage-controller IC rather than a memory package or a complete SSD. Its Gen4 x4 interface provides a high-bandwidth path between a host computer and the NAND storage subsystem.
Key verified features include four PCIe lanes at 16 Gb/s, NVMe 1.4 support, eight NAND channels, quad-core ARM R8 processing, NANDXtend ECC, SRAM ECC, and end-to-end data-path protection. The controller is intended for SSDs rather than general-purpose computing, and its performance depends on the selected NAND packages, firmware, DRAM configuration, thermal design, and the complete SSD implementation. Exact core frequency, power ratings, operating temperature, package dimensions, and NAND-interface data rate were not included in the provided data and are marked for validation.
The SM2264 is suitable for client NVMe SSDs, compact M.2 drives, high-performance gaming storage, industrial storage platforms, and automotive SSD designs when the system requirements match the controller and its qualified firmware. Automotive implementations may require the automotive-qualified SM2264XT-AT variant and full product qualification rather than the standard SM2264 designation.
Designers should validate the complete reference design, PCB stack-up, power rails, NAND compatibility, firmware release, thermal solution, and end-to-end data-integrity requirements before production. PCIe Gen4 x4 link integrity, power delivery, NAND routing, and thermal margin are critical because controller features alone do not determine final SSD performance. This page synthesizes the verified manufacturer and industry-source material, while unavailable electrical, package, pinout, pricing, and lifecycle details remain explicitly unconfirmed.

Aplicações típicas
SM2264 é adequado para 6 aplicaçãos: PCIe Gen4 x4 Client NVMe SSD, M.2 2280 High-Performance SSD, Small-Form-Factor NVMe Storage, Gaming NVMe SSD, Industrial NVMe Storage Platform, Automotive SSD Controller Platform.
PCIe Gen4 x4 Client NVMe SSD
The SM2264 fits client SSDs that need a PCIe Gen4 x4 host interface and NVMe 1.4 support. Its four lanes at 16 Gb/s per lane provide the host-facing bandwidth foundation for high-throughput storage, while the quad-core ARM R8 CPU handles controller-side processing. Designers should pair it with validated 3D NAND, firmware, DRAM configuration, power delivery, and thermal management because the controller specification alone does not determine final sequential or random performance. The resulting SSD should be validated for PCIe link training, power-state transitions, error recovery, and sustained workloads.
Recomendado
M.2 2280 High-Performance SSD
The SM2264 is suitable for an M.2 2280 SSD platform using PCIe Gen4 x4 and NVMe 1.4. The controller's four-lane 16 Gb/s interface, eight NAND channels, NANDXtend ECC, SRAM ECC, and end-to-end data-path protection support a high-performance solid-state drive architecture. Actual M.2 2280 compatibility depends on the physical PCB, connector, power states, thermal pad or heatsink implementation, and validated firmware. A thermal solution is particularly important in compact enclosures where sustained SSD workloads can raise controller and NAND temperatures.
Recomendado
Small-Form-Factor NVMe Storage
The SM2264's support for compact SSD architectures makes it relevant to small-form-factor storage designs where board area, power efficiency, and PCIe bandwidth must coexist. The manufacturer targets emerging small-form-factor SSDs in addition to mainstream client drives. Designers must confirm the exact package, pinout, PCB land pattern, power rails, and thermal envelope before layout. Because those physical and electrical details are not present in the supplied verified snippets, they remain [DATA_NEEDED: package, pinout, power, and thermal data] rather than being assumed.
Recomendado
Gaming NVMe SSD
A gaming SSD can use the SM2264 when the design requires PCIe Gen4 x4 throughput and NVMe 1.4 behavior for fast loading and high-bandwidth storage. The verified search material identifies an SM2264-based ADATA Legend 960 M.2 2280 SSD, confirming a commercial gaming-oriented use case. The controller should still be validated with the intended NAND and firmware for sustained performance, low-power states, thermal throttling behavior, and console or PC compatibility. Final drive performance is a system-level result rather than a guaranteed controller specification.
Recomendado
Industrial NVMe Storage Platform
The SM2264 can form the basis of an industrial NVMe storage platform when the selected SSD design requires PCIe Gen4 x4, 3D NAND support, and controller-level data-integrity features. NANDXtend ECC, SRAM ECC, and end-to-end data-path protection address important NAND reliability concerns. Industrial qualification still requires product-specific temperature, endurance, power-failure, shock, vibration, and lifecycle validation. Those requirements are not supplied for the standard SM2264 and must be established with the manufacturer and the complete SSD design.
Recomendado
Automotive SSD Controller Platform
The automotive use case is supported by the SM2264 family's stated automotive SSD targeting, while the verified material more specifically identifies SM2264XT-AT as a fully automotive-qualified PCIe Gen4 x4 controller with SR-IOV capability. Automotive programs should use the exact qualified MPN rather than treating the standard SM2264 designation as automatically qualified. The design must validate temperature, vibration, shock, data retention, power-loss behavior, firmware lifecycle, functional safety expectations, and vehicle-level EMC requirements. The supplied data does not provide the standard SM2264's numeric automotive ratings.

Notas de projeto
Validate the controller power rails, sequencing, current limits, and SSD power-state transitions against the controlled manufacturer reference design. The supplied verified sources identify a PCIe Gen4 x4 controller and quad-core ARM R8 CPU but do not provide SM2264 power ratings, so do not estimate rail budgets from generic SSD controllers. Confirm steady-state and transient requirements at the exact NAND, DRAM, and firmware configuration.
Plan thermal management at the controller, DRAM, and NAND levels, especially for M.2 2280 and small-form-factor products. Use the manufacturer's validated thermal design, account for sustained sequential and random workloads, and verify temperature behavior in the final enclosure. Thermal throttling and retention effects must be characterized with the actual NAND and firmware; no thermal resistance or maximum junction temperature was supplied.
Obtain the controlled SM2264 package drawing, pinout, reference PCB, and land pattern before routing. Pay particular attention to high-speed PCIe lanes, NAND channels, power delivery, grounding, and signal-return paths. A four-lane PCIe Gen4 interface and eight NAND channels require disciplined differential routing and impedance control, but exact stack-up and trace geometry cannot be responsibly inferred from the supplied search snippets.
Do not substitute an automotive or DRAM-less controller solely because it is also marketed for PCIe Gen4 x4 SSDs. SM2264XT-AT is described as automotive qualified and includes SR-IOV, while the search results describe SM2268XT as DRAM-less; neither establishes pin-to-pin or drop-in equivalence with SM2264. Confirm package, pinout, NAND compatibility, firmware, power, and qualification before considering any replacement.
Informações de conformidade
The supplied manufacturer and industry snippets do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for the standard SM2264. The SM2264XT-AT is described as fully automotive qualified in the supplied automotive source, but the exact qualification framework and evidence require manufacturer confirmation.
