![KSZ8862](/image/microchip/medium-KSZ8862-PQFP-128.png)
The KSZ8862M is 2-port switch with fiber support, available in 8-/16-bit and 32-bit bus designs.
The KSZ8862M is an industry first, fully managed, 2-port switch. It is based on a proven, 4th generation, integrated Layer-2 switch, compliant with IEEE 802.3u standards.
For industrial applications, the KSZ8862M can run in half-duplex mode regardless of the application. In fiber mode, port 1 can be configurable to either 100BASE-FX or 100BASE-SX/10BASE-FL. The LED driver and post amplifier are also included for 10Base-FL and 100Base-SX applications.
In copper mode, port 2 supports 10/100BASE-T/TX with HP Auto MDI/MDI-X for reliable detection of and correction for straight-through and crossover cables.
Microchip's proprietary LinkMD® Time Domain Reflectometry (TDR) based function is also available for determining the cable length, as well as cable diagnostics for identifying faulty cabling.
The KSZ8862M offers an extensive feature set that includes tag/port-based VLAN, quality of service (QoS) priority management, management information base (MIB) counters, and CPU control/data interfaces to effectively address Fast Ethernet applications.
The KSZ8862M contains:
- Two 10/100 transceivers with patented, mixed-signal, low-power technology
- Two media access control (MAC) units
- Direct memory access (DMA) channel
- High-speed, non-blocking, switch fabric
- Dedicated 1K entry forwarding table
- On-chip frame buffer memory
When using the provided KSZ8462 software driver, please exclude the 1588 PTP code at compile time.
Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The is subject to Microchip's and requires a myMicrochip account.

- IPV6 Multicast Listener Discovery (MLD) snooping support
- Integrated LED driver and post amplifier for 10BASE-FL and 100BASE-SX optical modules
- 100BASE-FX/SX and 10BASE-FL fiber support on port 1
- Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port
- MIB counters for fully compliant statistics gathering - 34 MIB counters per port
- Loopback modes for remote failure diagnostics
- Control registers configurable on-the-fly (port-priority, 802.1p/d/Q)
- Per port, 802.1p and DiffServ-based
- Remapping of 802.1p priority field on a per port basis
- Full-chip hardware power-down (register configuration not saved) allows low power dissipation
- Per port-based, software power-save on PHY (idle link detection, register configuration preserved)
- Single power supply: 3.3V
- Commercial Temperature Range: 0°C to +70°C
- Industrial Temperature Range: –40°C to +85°C
- (see Ordering Information).
- Available in 128-pin PQFP
