Overview

The KSZ8864RMNI is a highly-integrated, Layer 2 managed 4-port switch with optimized design, plentiful features and small package size.  The KSZ8864Automotive qualified (AEC-Q100). 

KSZ8864RMNI is designed for cost-sensitive 10/100Mbps 4-port switch systems.  On-chip termination, low-power consumption, and small package to save system cost. KSZ8864RMNI utilizes a shared memory-based switch fabric with full non-blocking configuration. KSZ8864RMNI 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.  KSZ8864RMNI provides multiple CPU control/data interfaces to effectively address a wide variety of fast Ethernet applications.The KSZ8864RMNI 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 registersthe 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 LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
