Overview

Description

LAN91C113-NU is an Ethernet controller from the LAN91Cxxx family (SMSC, now Microchip). It provides a 10/100 Mbps MAC and PHY in one chip to add network connectivity to embedded systems. The device is controlled by a host MCU/CPU via a parallel/PCI-type interface (depending on packaging) and includes TX/RX logic and packet buffers. It supports 10/100 auto-negotiation, half/full duplex modes, and standard IEEE 802.3 Ethernet frames. Typically a software driver is needed to initialize the hardware, configure speed/duplex, and manage packet transfers (often via DMA or I/O). It’s an older, well-documented part still seen in legacy designs, with newer LAN91Cxxx/LAN9xxx parts offering updated features. For exact pinout, interface mode, register map, and RAM requirements, consult the LAN91C113-NU datasheet and programmer’s guide.
