Mingjiada Electronics Supplies and Purchases ASM225: One-Stop Service for USB 3.2 Gen1 to SATA 6Gbps Bridge Chips—In-Stock and Recycling

In the USB-to-SATA storage bridge chip market, ASMedia’s ASM225 is a mainstream controller solution widely adopted in portable hard drive enclosures, mSATA external enclosures, and Type-C to SATA adapters. Shenzhen Mingjiada Electronics Co., Ltd. has long supplied brand-new, original ASM225 chips in stock to global customers, while also purchasing surplus inventory of this model at competitive prices, providing storage device manufacturers, solution design companies, and distributors with a complete, closed-loop supply chain—from “sourcing components” to “inventory clearance.”

Product Overview: What Is the ASM225 Chip?

The ASM225 is a next-generation USB 3.2 Gen1-to-SATA 6Gbps single-chip bridge solution launched by ASMedia, specifically designed for USB Type-C storage applications. The chip integrates complete bridging functionality between the USB 3.2 Gen1 host interface and the Serial ATA device interface. It also incorporates ASMedia’s proprietary SuperSpeed and High Speed PHYs, as well as SATA 1.5/3.0/6.0 Gbps PHYs, and features built-in CC logic to enable reversible plugging and automatic direction detection for USB cables.

Key Technical Features

① 5 Gbps USB 3.2 Gen1 + 6 Gbps SATA dual high-speed channels. The ASM225 supports the USB 3.2 Gen1 standard with a theoretical bandwidth of 5 Gbps and is backward compatible with the USB 3.1 Specification Revision 1.0 and the USB 2.0 specification; The SATA side is compatible with the full range of SATA 1.5/3.0/6.0 Gbps signal bandwidths, fully unleashing the performance potential of SATA III SSDs. In actual end-user products, portable hard drive enclosures using the ASM225, combined with the UASP acceleration protocol, can achieve transfer speeds in the range of 450 MB/s.

② Native Type-C CC logic with reversible plugging support. The chip features built-in CC logic circuitry that complies with the USB Type-C specification Revision 1.1, enabling cable orientation detection and reversible plugging without the need for an external CC controller, significantly reducing the design complexity of Type-C storage devices.

③ Support for UASP and TRIM ensures SSD performance is fully utilized. The ASM225 supports the USB Attached SCSI Protocol (UASP) Revision 1.0. When used with a UASP-compatible host and SSD, it reduces protocol overhead and improves read/write efficiency. It also supports TRIM commands, which help maintain the SSD’s long-term write performance and lifespan.

④ High integration simplifies peripheral circuitry. The chip integrates an 8-bit microprocessor, embedded program RAM and ROM, supports SPI NVRAM for manufacturer-customized applications, and provides multiple GPIO pins and programmable PWM outputs. It features two internally integrated voltage regulators—one for I/O power and one for the core—and requires only a 25 MHz external crystal oscillator to operate.

⑤ Spread-spectrum control improves EMI. The ASM225 supports Spread Spectrum Control for USB 3.0 and SATA interfaces, which helps optimize system-level EMI margins and offers practical engineering value for end products requiring electromagnetic compatibility (EMC) certification.

⑥ Compact, eco-friendly packaging. It uses a 6mm × 6mm QFN 48L lead-free, eco-friendly package that complies with RoHS standards, making it suitable for space-constrained portable storage device designs.

Typical Application Scenarios

The ASM225 has a broad range of applications in the storage bridging field, primarily focused on the following categories of end products:

2.5-inch/3.5-inch portable hard drive enclosures and docking stations: Acts as a controller chip to drive SATA HDDs/SSDs for USB plug-and-play functionality, supporting high-capacity drives.

mSATA SSD external enclosures: Provide a 5 Gbps USB bridge for mSATA modules, supporting power and access status LED indicators.

USB Type-C to SATA adapters/docking stations: Compatible with both PC and Mac platforms without requiring drivers; supports 2.5-inch hard drives and SSDs with thicknesses of 7 mm and 9.5 mm, with a maximum capacity of 10 TB.

For customers currently evaluating solutions or seeking sources for the ASM225, the application scenarios mentioned above correspond to different procurement batch sizes and packaging requirements. Mingjiada Electronics can provide tailored ordering recommendations and inventory matching based on the type of end product.
