LAN91C96I-MU

Controllers Overview

The LAN91C96I-MU is a non-PCI single-chip full duplex Ethernet controller manufactured by Microchip Technology. It integrates MAC and physical layer functions for 10BASE-T networks, featuring a 6K byte on-chip packet RAM and a hardware Memory Management Unit (MMU). The device supports IEEE 802.3 standards with automatic TX/RX polarity reversal detection and enhanced power management including Magic Packet technology. It operates within an industrial temperature range of -40°C to +85°C and accepts a supply voltage between 4.5V and 5.5V. The component utilizes a TQFP-100 package and provides AUI and PCMCIA interface options.

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm that the delivered units match the specified industrial temperature rating and RoHS compliance requirements before integration into production designs.

Controllers Selection Notes

Select this controller for applications requiring high integration of MAC and PHY functions without PCI bus dependencies. Consider the 6K byte memory buffer for systems with increased latency or simultaneous traffic demands. Verify compatibility with existing software drivers designed for the LAN91C92 and LAN91C94 series if migrating from legacy architectures.

Controllers Part Context

This component belongs to the LAN91C96 family of Ethernet controllers. It is pin and software compatible with the LAN91C92 and LAN91C94 in local bus mode. The device represents a VLSI solution combining local bus interfaces with integrated physical layer capabilities for twisted pair networks.

Controllers Replacement Considerations

The LAN91C92 and LAN91C94 are confirmed pin-compatible replacements in local bus mode. Verify software driver compatibility when substituting these models.
