MCHPLAN91C111-NS
Overview
The LAN91C111-NS is a single-chip 10/100 Ethernet controller designed to provide easy network connectivity for embedded microprocessors. It integrates a MAC and PHY into a single 128-pin QFP package, supporting a wide range of host interfaces including ARM, Coldfire, and MIPS.
Why Choose This Part
This controller features a flat MMU architecture with symmetric transmit and receive structures, simplifying driver development. It reduces BOM cost and complexity by integrating wave-shaping and an adaptive equalizer, eliminating the need for external filters.
Applications
Getting Started
To begin development, interface the controller to your host processor via the 16-bit or 32-bit bus. Ensure the optional serial EEPROM is configured if custom MAC addresses or power-up defaults are required. Review the 5V tolerant I/O specifications when connecting to older logic families.
