I. ASMedia PCIe Gen2 Switch Chips: Core Components for High-Speed I/O Expansion

ASMedia’s PCIe Gen2 data packet switch chip product line covers multiple specification tiers ranging from 6 lanes to 24 lanes. Products are categorized by the number of lanes and downstream ports, with the “I” suffix distinguishing industrial-grade from commercial-grade versions. These chips are widely used in servers, system storage, communication platforms, embedded systems, and industrial control applications.

Chips in this series share the same Gen2 switching architecture and power management features. They support L0s/L1/L23/L3 power-saving states, L1 substate deep power-saving mode, S3/S4 wake-up functions, independent port disable control, LTR, AER, and upstream/downstream port SRIS support. They feature a maximum payload of 512 bytes and support hot-swapping and accidental removal.

II. Key Models and Technical Specifications Acquired by Mingjiada Electronics

ASM1824: 24 lanes / 12 ports, flagship switching chip

The ASM1824 is the highest-spec packet switching chip in ASMedia’s PCIe Gen2 product line, featuring 24 lanes and up to 12 downstream ports. The upstream ports support 1/2/4/8-lane configurations and automatically detect lane configurations upon startup. Each lane supports two speed tiers: 2.5 Gb (250 MB/s) and 5 Gb (500 MB/s). The theoretical bandwidth of the x8 Gen2 upstream port reaches 4 GB/s (32 Gbps), while the 12 downstream ports share the total bandwidth. It supports various flexible configurations, including 2 x8 ports, 4 x4 ports, or 2 x4 + 2 x2 + 4 x1 ports, and is packaged in a 21 mm × 21 mm LFBGA-492L package.

Typical Applications: Multi-NVMe storage arrays, high-density high-speed network card scenarios, I/O aggregation for communication platforms, and industrial systems with a large number of PCIe devices.

ASM1812 / ASM1812I: 12 Lanes / 6 Ports—A Balanced Mid-Range Choice

The ASM1812 is positioned as a 12-lane PCIe Gen 2 switch chip with up to 6 downstream ports. It supports 1/2/4-lane upstream connections and distributes 8 lanes of PCIe 2.0 to up to 6 downstream ports, with per-channel speeds supporting both 2.5 Gb and 5 Gb. The theoretical bandwidth of the x4 Gen 2 upstream connection is 2 GB/s (16 Gbps), shared among the 6 downstream ports. It is packaged in a 21mm × 21mm LFBGA-492L package, sharing the same package dimensions as the ASM1824.

The ASM1812I is the industrial-grade version, with technical specifications identical to those of the ASM1812. The only difference lies in the operating temperature range—-40°C to 85°C—making it suitable for harsh environments such as industrial control cabinets, in-vehicle equipment, outdoor communication cabinets, and base stations.

Typical applications: 4-port 2.5GbE network cards, multi-device expansion cards, industrial control systems, and I/O expansion for communication base stations.

ASM1806 / ASM1806I: 6 Lanes / 4 Ports, Entry-Level Low-Cost Solution

The ASM1806 is an entry-level switch chip in ASMedia’s PCIe Gen2 series. It features 6 lanes and up to 4 downstream ports, with upstream support for 1 or 2-lane connections to the root port. Leveraging PCIe Gen2×2 upstream bandwidth, it supports the construction of high-speed I/O systems, with per-channel data rates of 2.5 Gb and 5 Gb. It has a maximum payload of 512 bytes and is packaged in a 10×10 mm QFN88 package.

The ASM1806I is the industrial-grade version, with an operating temperature range of -40°C to 85°C, while the ASM1806 is the commercial-grade standard version, with an operating temperature range of 0°C to 70°C. The ASM1806I has a typical power consumption of approximately 2.8 W and a theoretical total bandwidth of approximately 30 Gbps (3.75 GB/s), positioning it as an entry-level Gen 2, low-cost, low-bandwidth expansion solution.

Typical Applications: PCIe-to-USB expansion cards, multi-port network cards, I/O expansion for embedded systems, and industrial control equipment.
