- Dual interface support: SPI (up to 14 MHz) and 8/16-bit parallel bus for flexible host microcontroller connectivity
- 24 KB on-chip SRAM buffer for simultaneous transmit and receive operations, supporting up to 8 receive filters
- IEEE 802.3 compliant with flow control, auto-negotiation, and full-duplex/half-duplex operation
Applications
The ENC424J600IPT is widely used in embedded systems and IoT applications that require standalone Ethernet connectivity without a full network stack processor, such as industrial sensors, energy meters, and remote monitoring nodes. Its SPI interface makes it straightforward to pair with low-cost 8-bit and 32-bit microcontrollers for adding 10/100 Mbps network access to existing designs. The compact 44-pin TQFP package and integrated MAC/PHY make it a cost-effective choice for smart building controllers, data loggers, and networked automation equipment.

Frequently Asked Questions
What host interface options does the ENC424J600IPT support for connecting to a microcontroller?
The ENC424J600IPT supports both a 4-wire SPI interface operating at up to 14 MHz and an 8-bit or 16-bit parallel bus interface, giving designers flexibility to connect it to a wide range of 8-bit, 16-bit, and 32-bit microcontrollers without additional bridge hardware.
How much on-chip buffer memory does the ENC424J600IPT provide for Ethernet frames?
The ENC424J600IPT includes 24 KB of on-chip SRAM that serves as a shared transmit and receive buffer, allowing the host processor to handle Ethernet frames at 10 Mbps or 100 Mbps while supporting up to 8 programmable receive filters for multicast, broadcast, and unicast traffic management.
What Ethernet standards does the ENC424J600IPT comply with and what are its maximum data rates?
The ENC424J600IPT is fully IEEE 802.3 compliant supporting 10BASE-T and 100BASE-TX operation with auto-negotiation, enabling half-duplex and full-duplex modes at speeds of 10 Mbps and 100 Mbps over standard CAT5 cable using an RJ-45 connector and external magnetics.
For a compact IoT sensor design, what package does the ENC424J600IPT come in and what is the pin count?
The ENC424J600IPT is packaged in a 44-pin TQFP (Thin Quad Flat Package) with a 10 mm x 10 mm body and 0.8 mm lead pitch, making it a manageable footprint for compact PCB designs while offering all required interface pins for SPI, parallel bus, and Ethernet PHY connections.
