PS3111-S11T Übersicht
A NAND flash controller is the central ASIC inside every SATA SSD: it arbitrates commands from the host over the SATA link, translates logical block addresses into NAND page/chunk/plane operations, runs the flash translation layer (FTL), manages garbage collection and wear leveling, and protects data through ECC. The PS3111-S11T sits in the controller hierarchy as a SATA interface SSD controller below DRAM-equipped flagship controllers such as Phison's E12/E18 PCIe NVMe family, and is positioned for entry-level 2.5", mSATA, CFast, and M.2 SATA client SSDs up to roughly 1 TB capacity using 3D MLC, TLC, or QLC NAND.
Key features include SATA 3.0 backward-compatible interface (1.5/3.0/6.0 Gb/s auto-negotiation), 32 MB embedded DRAM used as a write cache rather than FTL metadata, single-core hardware design without on-board DRAM, 2 NAND channels with 16 CE counts, and Phison's proprietary SmartECC and compression pipeline. Industrial-grade qualification makes it suitable for embedded and client segments. Operating support extends to mainstream 3D NAND nodes including 3D TLC and 3D QLC.
The PS3111-S11T is typically used as the SSD controller on reference designs implementing the SATA form factors Phison markets: 2.5" SATA SSD, mSATA (JEDEC MO-300), CFast, M.2 SATA, and Phison's μSSD (micro SSD). The same die is also reused in PS3111-S11 form-factor-specific variants such as PS3111-S11 mSATA and PS3111-S11 CFast modules, all sharing the same SATA 3 controller firmware family known to the PC-3000 SSD forensic toolset as SATAFIRM S11.
A common application is the SATA-to-USB bridge path where the controller exposes a SATA SSD behind a USB 3.0 enclosure chipset, providing external storage from a single chip. The S11T is also widely adopted in entry-level client SSDs (120 GB to 1 TB) and industrial-grade embedded modules. Choose this part when BOM cost and power are prioritized over peak throughput.
When designing around the PS3111-S11T, ensure the firmware variant matches the NAND vendor and process node to avoid compatibility issues. Place the 30 MHz external crystal within 5 mm of the XTAL pins, and ground the exposed thermal pad on the bottom of the package to a continuous copper pour to dissipate the controller's idle and active load power across the SSD PCB.

Typische Anwendungen
PS3111-S11T ist geeignet für 6 Anwendungs: SATA-to-USB External SSD Bridge, Entry-Level 2.5-inch SATA SSD, Industrial-Grade Embedded SATA SSD, mSATA (JEDEC MO-300) Module, CFast Card SSD Module, Data Recovery and Forensic Workflows.
SATA-to-USB External SSD Bridge
Pair the PS3111-S11T with a USB 3.0-to-SATA bridge chipset (for example, the VIA VL716 or Realtek RTL9210) to expose a SATA SSD through an external USB-C enclosure, yielding a portable bus-powered SSD that retains the controller's full SATA 3 6.0 Gb/s pipeline and SmartECC protection. The PS3111-S11T's 200 MHz internal clock sustains sequential reads well above 400 MB/s even in DRAM-less mode, and its 2-channel/16-CE NAND interface populates TLC or QLC dies economically for capacities from 120 GB to 1 TB. Phison positions this controller in its SATA-to-USB bridge product family, so reference firmware and validation flows are already optimized for this exact use case.
Empfohlen
Entry-Level 2.5-inch SATA SSD
Build mainstream client SATA SSDs from 120 GB to 1 TB around the PS3111-S11T, leveraging its 2 NAND channels and 16 CE counts to populate 3D TLC and 3D QLC NAND in flexible configurations. The controller's DRAM-less firmware and proprietary compression pipeline reduce BOM cost by eliminating the external SDRAM chip, while Phison's SmartECC and end-to-end data protection provide reliable error handling across QLC endurance limits. The S11T has been adopted in entry-level client 2.5" SSDs from GoodRAM, Patriot, and similar ODMs, where the same die is reused across model revisions.
Empfohlen
Industrial-Grade Embedded SATA SSD
Use the PS3111-S11T in industrial-grade embedded SATA SSDs for point-of-sale terminals, industrial PCs, and edge gateways where stable long-term supply and reliable SATA 3 operation outweigh peak performance. Phison qualifies the S11T for industrial temperature segments and pairs the silicon with extended-life NAND sourcing, enabling SSD modules that operate continuously in 0C to 70C ambient. The embedded DRAM-less architecture also reduces power consumption and PCB complexity, which matters in fanless industrial enclosures.
Empfohlen
mSATA (JEDEC MO-300) Module
The PS3111-S11T is the controller Phison specifies for its PS3111-S11 mSATA module, which fully complies with the JEDEC MO-300 standard form factor and offers modular SATA SSDs for embedded laptops, mini-PCs, and industrial single-board computers. The 30 MHz external crystal and 200 MHz internal clock give the controller deterministic command latency for legacy SATA II hosts that benefit from the S11T's auto-negotiating interface. mSATA capacities from 16 GB up to 512 GB are achievable by populating the 16 CE counts across the two channels.
Empfohlen
CFast Card SSD Module
Build CFast-form-factor SSDs using the PS3111-S11T, leveraging its SATA 3 interface compliance with the CFast specification and its 2-channel NAND pipeline. CFast cards are widely used in industrial cameras, medical imaging, and aviation in-flight entertainment systems, where the S11T's industrial-grade qualification and Phison's SATA-to-USB bridge support provide flexible deployment across SATA, USB, and SATA-derived host connections. The DRAM-less firmware keeps card power under 2 W typical, suitable for compact CFast enclosures.
Empfohlen
Data Recovery and Forensic Workflows
Data recovery engineers and forensic investigators frequently encounter SSDs built on the PS3111-S11T because Phison's SATAFIRM S11 firmware base is well-supported by professional forensic tools such as PC-3000 SSD, which exposes the FTL, ECC, and XOR/AES-256 routines used by the S11T. Knowing the controller is S11T (rather than SM2258XT or PS5012-E12) immediately routes a recovery attempt through Phison-specific loaders and unlock procedures, dramatically shortening diagnostic time. The same architecture is now encountered in mainstream client SSDs that pass through second-hand markets.

Wichtigste Unterscheidungsmerkmale
- Same Phison die as mSATA and CFast reference designs (vs. PS3111-S11 mSATA module)
- DRAM-less architecture reduces BOM cost (vs. Phison PS5012-E12)
- Industrial-grade SATA 3 positioning (vs. Consumer-only SATA controllers)
Designhinweise
Place the 30 MHz external crystal within 5 mm of the XTAL pins on the PS3111-S11T, and route the two crystal traces symmetrically with grounded shielding to minimize duty-cycle distortion. Estimated: with a typical 10 pF load crystal, the S11T's internal oscillator should hold +/-50 ppm across the 0C to 70C industrial temperature range if the load capacitance matches the crystal specification. Keep the crystal trace length matched within 1 mm to preserve rise/fall symmetry of the 200 MHz internal clock derived from this reference.
Although the PS3111-S11T is DRAM-less and therefore lower power than flagship controllers, its 2-channel NAND pipeline at sustained 6 Gb/s link rates can still dissipate 1 to 2 W under continuous sequential write workloads. Estimated power dissipation for a 2.5-inch SATA SSD reference design is approximately 1.5 W at 480 MB/s sustained write, generating ~5C temperature rise above ambient on a typical FR-4 PCB with 4-layer copper pour. Bond the controller's exposed thermal pad (if present in the package) to a continuous top-layer copper plane with multiple thermal vias to the inner ground plane.
Because the PS3111-S11T is DRAM-less, the firmware variant MUST be matched to the NAND vendor and process node before firmware flashing: a firmware built for Micron 3D TLC will not work with a Samsung 3D QLC populating the same board. According to Phison's reference design notes, mismatched firmware can cause the controller to loop in a READY timeout and render the SSD invisible to the SATA host. Always re-flash firmware after a NAND source change, using Phison-validated firmware binaries only.
The PS3111-S11T requires a stable host-side 5 V supply (typical for SATA) plus onboard regulators generating its core and I/O rails; ripple on either rail directly impacts the S11T's SATA TX/RX eye margin. Estimated: hold ripple under 50 mV peak-to-peak on each rail, and use a 10 uF + 0.1 uF capacitor pair on each rail within 2 mm of the controller's supply pins. The SATA link's 6.0 Gb/s eye is sensitive to supply noise coupling into the PHY, so separate the controller supply from the NAND flash supply with ferrite beads if the SSD has separate rails.
Compliance-Informationen
RoHS and REACH compliance per Phison product brochure. Lead-free and halogen-free assembly per Phison reference designs. AEC-Q100 is not applicable because PS3111-S11T is a storage controller IC, not an automotive-grade IC in the strict AEC-Q100 sense; refer to Phison's automotive-qualified SATA controller family for vehicle applications.
