Device Overview

Summary

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 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.

KSZ8864CNX EVAL BOARD
KSZ8864CNX EVAL BOARD ( KSZ8864CNX-EVAL )

The KSZ8864 device consists of two PHYs and four MACs. Two of MACs support either MII or RMII interfaces for dual processor/DSP data transfer. Higher speed SPI and MDC/MDIO interfaces can fully manage the 4-port switch by the processor. The device had been designed with cost sensitive systems in mind but still offers a multitude of features such as switch management; port and tag based VLAN;...
