The LAN91C96 is a VLSI Ethernet Controller that combines Local Bus, PCMCIA, and Motorola 68000 bus interfaces in one chip. LAN91C96 integrates all MAC and physical layer functions, as well as the packet RAM, needed to implement a high performance 10BASE-T (twisted pair) node. For 10BASE5 (thick coax), 10BASE2 (thin coax), and 10BASE-F (fiber) implementations, the LAN91C96 interfaces to external transceivers via the provided AUI port. Only one additional IC is required for most applications. The LAN91C96 comes with Full Duplex Switched Ethernet (FDSWE) support allowing the controller to provide much higher throughput. 6K bytes of RAM is provided to support enhanced throughput and compensate for any increased system service latencies. The controller implements multiple advanced power-down modes including Magic Packet to conserve power and operate more efficiently. The LAN91C96 can directly interface with the Local Bus, PCMCIA, and 68000 buses and deliver no-wait-state operation. *The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.

Instructions for Use

1. Power Supply:

   • Connect the 3.3V supply to the VCC pins and the 5V supply to the VIO pins.
   • Ensure proper decoupling capacitors are placed close to the power pins.

2. Clock Input:

   • Provide a 25 MHz clock signal to the XIN pin.

3. Host Interface:

   • Connect the 16-bit or 8-bit ISA bus to the appropriate data and control lines.
   • Configure the base address for the LAN91C96 using the address select pins.

4. MAC Address Configuration:

   • Program the 48-bit MAC address into the on-chip EEPROM or set it via software.

5. Transceiver Connection:

   • Connect the integrated 10BaseT transceiver to the RJ45 connector using the appropriate differential pairs (TX+/TX-, RX+/RX-).

6. LED Control:

   • Connect the LED control outputs to external LEDs to indicate link status and activity.

7. Interrupt Handling:

   • Configure the interrupt enable registers to generate interrupts for specific events.
   • Connect the INT pin to the host interrupt line.

8. DMA Configuration:

   • Set up DMA channels for efficient data transfer between the host memory and the LAN91C96.

9. EEPROM Programming:

   • Use the on-chip EEPROM to store configuration settings such as MAC address, default register values, and other parameters.

10. Firmware/Driver:

    • Load the appropriate firmware or driver to initialize and control the LAN91C96.

11. Testing:

    • Verify the operation by connecting to a network and testing data transmission and reception.

For detailed programming and configuration, refer to the LAN91C96 datasheet and application notes provided by the manufacturer.
