Application Notes:
Brochures:
The KSZ8842-series of 2-port switches includes PCI and non-PCI CPU interfaces.
The datasheet describes the KSZ8842-PMQL/PMBL PCI CPU interface chips. KSZ8842-PMQL is PQFP package chip, KSZ8842-PMBL is LFBGA package chip. For information on the KSZ8842-MQL/MBL CPU non-PCI interface switches, refer to the KSZ8842-MQL/MBL datasheet.
The KSZ8842-PMQL/PMBL is the industry's first fully managed 2-port switch with a 32-bit/33MHz PCI processor interface. It is a proven, 4th generation, integrated Layer 2 switch that is compliant with the IEEE 802.3u standard. An industrial temperature grade version of the KSZ8842-PMQL/PMBL, also can be ordered the KSZ8842-PMQLI/PMBL AM. The KSZ8842-PMQL/PMBL can be configured as a switch or as a low-latency (<310 nanoseconds) repeater in latency-critical, embedded or industrial Ethernet applications.
For industrial automation applications, the KSZ8842-PMQL/PMBL can run in half-duplex mode regardless of the application. The KSZ8842-PMQL/PMBL 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 KSZ8842-PMQL/PMBL contains two 10/100 transceivers with patented, mixed-signal, low-power technology three media access control (MAC) units, a direct memory access (DMA) channel, a high-speed, non-blocking, switch fabric, a dedicated 1K entry forwarding table, and an on-chip frame buffer memory.
Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
- There are three kinds of register groups:
- The PCI configuration registers are used to initialize and configure the PCI interface
- The PCI control/status registers are used to communicate between the host and KSZ8842-PMQL/PMBL
- Switch registers are used to support transceiver control and status. They are configurable on-the-fly (port-priority, 802.1p/d/Q, etc.)
- Per port, 802.1p and DiffServ based
- Re-mapping of 802.1p priority field on a per port basis
- Full-chip hardware power-down (register configuration not saved) provides for 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
- Available in 128-pin PQFP and 100-ball LFBGA
