Status: In Production
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.
