ASM1184E

The ASM1184E is a PCIe switch chip developed by ASMedia Technology. It provides one PCIe 3.0 upstream port and splits it into four downstream ports, enabling expansion of PCIe lanes for multiple devices (e.g., GPUs, SSDs, or NICs).
Key features:
- PCIe 3.0 x4 upstream (supports bifurcation).
- Four PCIe 3.0 x1 downstream ports (configurable via BIOS).
- Low power consumption and compact design.
- Plug-and-play support (no drivers needed).
Commonly used in motherboards, riser cards, and mining rigs, it helps overcome PCIe slot limitations. However, bandwidth is shared, so performance may vary under heavy multi-device loads.
For optimal use, ensure proper BIOS settings (e.g., bifurcation enabled) and adequate cooling.

The ASM1184E is a PCIe switch chip. Equivalent alternatives include:
- Pericom PI7C9X2G404SL (now owned by Diodes Inc.)
- Microchip (Microsemi) PM8536
- Broadcom (Avago) PEX8604
- Texas Instruments XIO2001
These chips offer similar PCIe switching functionality, though pin compatibility and features may vary. Check datasheets for exact specifications.

The ASM1184E is a PCIe packet switch with the following key features:
- 4-lane, 4-port PCIe Gen 2 switch (5 Gbps per lane).
- Supports hot-plug and surprise removal for flexible connectivity.
- Non-transparent bridging (NTB) for multi-host communication.
- Low power consumption with advanced power management.
- Flexible port configurations (x1, x2, x4) for varied bandwidth needs.
- Supports legacy PCI compatibility for backward integration.
- Built-in error handling with ECRC and advanced error reporting.
- Compact QFN package (9x9mm) for space-constrained designs.
Ideal for embedded systems, storage, and multi-host applications.
