Product Details
KSZ8993MI - Industrial Three-Port 10/100 Managed Ethernet Switch
KSZ8993MI from Microchip Technology is an industrial-temperature three-port Fast Ethernet switch with two integrated PHYs and a configurable host/MAC port in a 128-pin PQFP.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
KSZ8993MI integrates two 10/100 Ethernet PHYs, three MACs and a managed Layer 2 switch with VLAN, QoS, address learning and multiple serial-management options.
Key Advantages
Provides two copper PHY ports plus a configurable host-facing third MAC over -40 C to +85 C.
Supports managed SPI, I2C, SMI and MIIM control or strap/EEPROM initialization.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
