LAN91C96TQFP

Controllers Overview

The LAN91C96TQFP is a single-chip Ethernet controller manufactured by SMSC, designed for embedded network interface card applications. It supports IEEE 802.3 standards with 10 Mbps data rates and operates in full-duplex mode. The device integrates 6 Kbytes of on-chip RAM for buffer management and features hardware Memory Management Unit (MMU) capabilities. It interfaces with host processors via PCMCIA, ISA, or Motorola 68000 buses. The component utilizes low-power CMOS technology and includes advanced power management features such as sleep modes and Magic Packet support.

Controllers Feature Summary

• Supports full-duplex transmission and reception with integrated sleep mode functionality
• Integrates 6 Kbytes of on-chip RAM for packet buffering and processing
• Features hardware MMU architecture for efficient memory access management
• Enables optional configuration through a serial EEPROM interface

Controllers Applications

• Embedded system network interface cards (NIC)
• Industrial control systems requiring compact networking solutions
• Motorola 68000-based processor platforms

Controllers Procurement Notes

Verify the specific suffix TQFP to confirm the thin quad flat package variant. Ensure compatibility with the target bus interface, whether PCMCIA, ISA, or Motorola 68000. Confirm RoHS compliance status if required for the assembly process. Check for lead-free specifications corresponding to the manufacturing date code.

Controllers Selection Notes

Select this component when a dedicated 10 Mbps Ethernet controller is required for embedded designs. It is suitable for systems utilizing Motorola 68000 architectures or standard ISA/PCMCIA slots. Consider the 6 Kbyte internal RAM limitation for high-throughput scenarios where external memory might be necessary.

Controllers Part Context

This part belongs to the LAN91C series of Ethernet controllers from SMSC. It serves as a specialized solution for integrating Ethernet connectivity into microcontroller-based systems without requiring separate MAC and PHY components. The TQFP designation indicates the specific surface-mount package type used for board integration.

Controllers Replacement Considerations

The LAN91C111I-NS is a documented successor offering dual-speed 10/100 Mbps capability. Verify pinout compatibility and software driver availability before substituting, as the newer model supports higher data rates and different bus interfaces.
