KSZ8995M

KSZ8995M is Microchip (Micrel)’s five-port Ethernet switch IC for embedded systems. It packs five Fast Ethernet (10/100 Mbps) PHYs and a built-in switch fabric, so you can connect five external RJ45 ports plus a CPU/mgmt interface without extra switch silicon. It’s aimed at small managed switches, gateways, and edge devices needing compact switching. Key features typically include 802.1Q VLANs, QoS with priority queuing, basic L2 switching (MAC learning, aging, forwarding), port-based controls, and host management via the MDIO (MDC/MDIO) interface. Some variants offer a dedicated CPU port and various power modes. Use it by configuring the switch registers from an MCU/SoC; it can operate in standalone or managed modes depending on the setup. For exact speeds, features, and the register map, consult Microchip’s KSZ8995M datasheet.

Here are the key features of KSZ8995M (5-port Gigabit Ethernet switch IC):
- 5 x 10/100/1000BASE-T ports; auto-Negotiation and auto MDI/MDIX per port
- Store-and-forward, high-performance switch fabric
- IEEE 802.1Q VLAN support (port-based and tagged) with VLAN filtering
- QoS with IEEE 802.1p, multiple priority levels, and bandwidth control
- Multicast support: IGMP snooping and multicast/broadcast filtering
- Large MAC address table with learning and aging; supports jumbo frames (up to ~9 KB)
- Management interfaces for configuration (MDIO/MDC and register access via host MCU)
- Per-port LED indicators; low-power modes and protection features (ESD)
- Compact package options suitable for embedded designs
Note: exact memory sizes and some interface details can vary by revision; consult the datasheet for precise numbers.

Pin count: 208-pin BGA (also available in other package options).
Function: KSZ8995M is a 5-port Ethernet switch device (five 10/100/1000BASE-T PHYs) with an integrated switch fabric and management interface (MDIO) for host control.

KSZ8995M is manufactured by Microchip Technology Inc. (originally Micrel Semiconductor). Microchip is a global semiconductor company that designs and manufactures ICs, including microcontrollers, analog/memory devices, and networking ICs such as Ethernet PHYs and switches.

KSZ8995M is a 5-port gigabit Ethernet switch intended for embedded and industrial/networking use. Typical applications include:
- Small home/office devices: routers/gateways, set‑top boxes, NAS, printers, media players
- Compact industrial automation and control equipment needing a managed L2 switch (VLAN, QoS, security basics)
- Edge switching for IP cameras and surveillance systems
- Networking modules, reference designs, and embedded development boards requiring an off‑the‑shelf switch
These make it suitable for compact, cost-effective network peripherals and integrated products.

KSZ8995M uses a QFN (quad‑flat no‑lead) package. Check the datasheet for the exact variant and pin count (e.g., QFN‑48) and available options.
