描述 Description

The KSZ8864 is a highly-integrated, Layer 2 managed 4-port switch with optimized design, plentiful features and small package size.?The KSZ8864 Automotive qualified (AEC-Q100).?KSZ8864 is designed for cost-sensitive 10/100Mbps 4-port switch systems.?On-chip termination, low-power consumption, and small package to save system cost. KSZ8864 utilizes a shared memory-based switch fabric with full non-blocking configuration.KSZ8864 also provides an extensive feature set including: power management, programmable rate limiting and priority ratio, tag/port-based VLAN, packet filtering, quality of service (QoS), four queue prioritization, management interface, and MIB counters. Ports 3 and 4 support either MII or RMII interfaces.?KSZ8864 provides multiple CPU control/data interfaces to effectively address a wide variety of fast Ethernet applications.The KSZ8864 contains four MACs and two PHYs. The two PHYs support the 10/100Base-T/TX. All registers of MACs and PHYs units can be managed by the control interface of SPI or the SMI. MIIM registers the PHYs can be accessed through the MDC/MDIO interface. EEPROM can set all control registers by I2C controller interface for the unmanaged mode.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.
