ENC624J600T-I/PT

Controllers Overview

The ENC624J600T-I/PT is a stand-alone Fast Ethernet controller manufactured by Microchip Technology, housed in a 64-pin TQFP package. It integrates a MAC and a 10/100Base-T PHY compliant with IEEE 802.3 specifications. The device supports data rates of 10 Mb/s and 100 Mb/s via SPI or parallel interfaces. It operates on a 3.0V to 3.6V power supply within an industrial temperature range of -40°C to +85°C. Key features include 24-Kbyte SRAM, hardware security engines for RSA, AES, MD5, and SHA-1, and automatic polarity detection.

Controllers Feature Summary

• Integrates a complete MAC and 10/100Base-T PHY with automatic polarity detection and correction.
• Includes hardware security acceleration engines supporting RSA, Diffie-Hellman, AES, MD5, and SHA-1 algorithms.
• Features a 24-Kbyte transmit/receive packet buffer SRAM with internal DMA and hardware IP checksum calculations.
• Supports flexible host communication through SPI or multiplexed/demultiplexed parallel interfaces.

Controllers Applications

• Microcontroller-based Ethernet network interface implementations
• Industrial control systems requiring secure data transmission
• Embedded devices needing standalone 10/100 Mbps connectivity

Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the '-I' designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Ensure the 64-pin TQFP footprint aligns with your PCB layout constraints before finalizing procurement.

Controllers Selection Notes

Select this component over the ENC424J600 if your design requires the additional parallel interface modes available only on the 64-pin package. Verify that the host microcontroller supports either the SPI protocol or one of the supported parallel bus configurations. Ensure the system provides a stable 25 MHz clock source as required by the oscillator circuitry.

Controllers Part Context

This part belongs to the ENC424J600/624J600 family of stand-alone Ethernet controllers. The primary distinction between the ENC424J600 and ENC624J600 is the pin count and parallel interface capabilities. The ENC624J600 utilizes a 64-pin TQFP package to support additional parallel bus modes compared to the 44-pin variants.

Controllers Replacement Considerations

The ENC424J600 serves as a functional alternative but differs in pin count (44-pin) and lacks the full parallel interface options found in the 64-pin variant. Direct substitution requires evaluating the host interface requirements and physical footprint compatibility.
