KSZ8895FQXIA

KSZ8895FQXIA is a five-port Ethernet switch IC from Microchip (formerly Micrel). It aggregates five 10/100/1000BASE‑T PHY/MAC interfaces into a single switch fabric, enabling embedded devices (routers, gateways, APs, media players) to connect multiple Ethernet ports without a separate switch chip. The device provides a host/CPU port, a management interface (MDIO/MDC), and supports standard Ethernet features such as VLANs, QoS, and frame filtering. The FQXIA suffix indicates a specific package and temperature grade. For exact port configuration, power pins, LEDs, and feature details (including PoE if applicable), consult the KSZ8895 datasheet and product brief.

KSZ8895FQXIA is Microchip’s KSZ8895 5‑port Gigabit Ethernet switch IC. There are no guaranteed pin‑compatible drop‑ins; usable equivalents are functionally similar 5‑port managed GigE switch ICs from Broadcom (BCM531xx series), Marvell (Prestera/88E6xxx family), Realtek (RTL83xx series), or other Microchip KSZ variants. For an exact cross‑reference, consult Microchip or your distributor.

Here are the key features of KSZ8895FQXIA (concise):
- 5-port Gigabit Ethernet switch: 4 external ports + 1 CPU/management port
- Each port supports 10/100/1000BASE-T with auto-negotiation and auto-MDIX
- VLAN support: IEEE 802.1Q (port-based and VLAN-based Bridging)
- QoS: 802.1p/DSCP, multiple queues, traffic shaping, and per-port rate limiting
- Multicast support: IGMP/MLD snooping for efficient multicast delivery
- Jumbo frames supported; robust switch fabric and MAC address table with aging
- Network protocols: Spanning Tree (RSTP/MSTP), link state/port mirroring
- Management: standard register-based management (MDIO/host interface as applicable), status LEDs
- Power and footprint: small package, low power operation
Note: exact host interface details (SPI/MDIO) and internal specs may vary by revision; consult the datasheet for precise interfacing options.

Pin count: 128 pins (128‑pin LQFP/QFN package variant).
Function (concise): KSZ8895F is a 5‑port 10/100 Mbps Ethernet switch IC with five integrated PHYs and a CPU/MAC management port. It provides hardware switching, VLANs, QoS, IGMP snooping, MIB counters, MAC address table, MDIO management, serial host interfaces (SPI/SMI/MDIO), and typical PHY controls (link/MDI/MDIX, LEDs, SGMII/MAC interface options), intended for embedded LAN/switching applications.

The KSZ8895FQXIA is from Microchip Technology Inc. (originally sold under Micrel’s KSZ family before Microchip acquired Micrel in 2015). Microchip is an American semiconductor company that designs and supplies microcontrollers, analog and mixed-signal ICs, EEPROM/Flash memory, and networking/interface devices. It is a global, publicly traded (NASDAQ: MCHP) provider of embedded control and connectivity solutions for industrial, automotive, consumer and communications markets.

KSZ8895FQXIA is a 5-port Gigabit Ethernet switch IC for embedded networks. Common application areas:
- Embedded/consumer SMB networking devices (routers, edge switches, gateways)
- IP cameras and video surveillance systems
- Industrial automation and machine-to-machine networks
- IoT gateways and smart home hubs
- Digital signage, POS terminals, and other compact network appliances

The KSZ8895FQXIA is supplied in a 128-pin LQFP (low-profile quad flat package). Check the datasheet for exact mechanical dimensions and land pattern.
