Against the backdrop of steadily rising demand for high-speed external storage devices, Asmedia’s ASM1352R—with its USB 3.2 Gen 2x1-to-dual-SATA 6 Gbps bridging capability—has become the core controller chip for portable hard drive enclosures, dual-bay storage docks, and industrial storage expansion solutions. Shenzhen Mingjiada Electronics Co., Ltd. is now offering brand-new, genuine Asmedia ASM1352R chips to the global market and is actively purchasing them at competitive prices on a long-term basis, providing customers with one-stop supply chain services ranging from spot purchases to inventory buybacks.
I. ASM1352R: A Single Chip Bridging USB 10 Gbps and Dual SATA Channels
The ASM1352R is a single-chip solution introduced by Asmedia for high-speed storage bridging applications, capable of bridging a USB 3.2 Gen2x1 interface to dual SATA device ports. Its USB PHY operates at speeds up to 10 Gbps and is fully compliant with the USB 3.1 specification; while the SATA PHY supports a signal bandwidth of 6Gbps and complies with the Serial ATA Revision 3.2 specification. This combination makes the ASM1352R a key component for USB-to-SATA port expansion and performance enhancement, suitable for both internal storage designs and a wide range of external storage applications.
1.1 Powered by HydraTek Technology: Flexible Hardware RAID Configuration
The ASM1352R integrates Asmedia’s proprietary HydraTek technology, supporting hardware-level RAID 0 (Strip), RAID 1 (Mirror), JBOD, and SPAN (BIG) modes. RAID modes can be switched via hardware jumpers, requiring absolutely no system CPU resources. In a RAID 0 configuration, when paired with two SATA III SSDs, it can achieve sequential read speeds exceeding 950 MB/s, providing a cost-effective, high-speed storage expansion solution for computer users without Thunderbolt ports.
1.2 Extensive Interface and Control Features
In terms of general-purpose functionality, the ASM1352R features a built-in 8-bit microprocessor equipped with embedded program RAM and ROM. It supports SPI NVRAM for vendor-specific applications and provides an I²C master mode interface along with multiple GPIO pins for LED indicators and storage power control. The chip also supports fan control, hard drive insertion detection, and an integrated core power switch regulator. It uses a 3.3V I/O power supply and a 1.2V core power supply, and is packaged in an 8mm × 8mm, 64-pin QFN that complies with RoHS environmental standards.
In terms of USB features, the ASM1352R supports SuperSpeedPlus, SuperSpeed, High-Speed, and Full-Speed operating modes and is compatible with the Mass Storage Class Bulk-Only Transport specification Rev 1.3 and the UASP protocol. In terms of SATA features, the chip supports NCQ commands, hard drive addressing beyond 2TB, staggered spin-up, SATA Partial/Slumber low-power states, and independent power-off control for each storage drive.
II. Typical Application Scenarios for the ASM1352R
Thanks to its high integration and flexible RAID configuration capabilities, the ASM1352R has been widely deployed in the following areas:
Dual-bay portable hard drive enclosures: Supports 2.5-inch or 3.5-inch SATA hard drives, connects to the host via a USB 3.2 Gen 2 Type-C interface, and achieves data transfer rates of up to 10 Gbps;
Professional storage docks: Features a built-in hardware RAID controller, suitable for professional scenarios requiring data redundancy or performance aggregation;
Industrial storage expansion modules: Utilizing the SATA port multiplier function to enable multi-bay storage expansion in embedded systems;
mSATA/M.2 SSD adapter solutions: Used in conjunction with mSATA or M.2 SATA SSDs to build compact external storage devices.
