What are the key features of PIC18F67J60-I/PT?
- Integrated 10/100 Ethernet MAC with MII interface enabling wired network connectivity without an external Ethernet controller chip
- 128 KB flash program memory with 41.667 MHz clock supporting TCP/IP stack execution alongside application code on a single 8-bit core
- 2 V minimum supply at 4 MHz enabling low-power Ethernet node operation from regulated supplies close to single-cell Li-Ion voltage
- 64-pin TQFP package with ADC and multiple UART/SPI/I2C peripherals reducing external component count in networked sensor designs
What is PIC18F67J60-I/PT used for?
The PIC18F67J60-I/PT is designed for embedded Ethernet applications such as web-enabled sensor nodes, networked industrial controllers, and remote monitoring systems that require a wired TCP/IP connection in a compact 64-pin TQFP form factor. Its integrated 10/100 Ethernet MAC eliminates the external Ethernet controller IC and its associated SPI overhead, simplifying firmware and reducing BOM cost for small-volume IoT gateway designs. The 128 KB flash provides enough space for a lightweight TCP/IP stack, HTTP server, and application logic simultaneously.

Frequently Asked Questions
Does the PIC18F67J60-I/PT include an Ethernet MAC, and what external components are still required for a complete Ethernet interface?
The PIC18F67J60-I/PT integrates a 10/100 Ethernet MAC with MII interface on-chip, eliminating the need for a separate Ethernet controller IC such as an ENC28J60. To complete the Ethernet interface, an external 10/100 PHY chip plus isolation magnetics are still required, but these add only 2–3 components compared to 5+ for a fully discrete solution. This integration reduces SPI bus overhead and improves throughput, as the MAC communicates directly with the MCU core rather than through a serial interface.
How much firmware code can fit in the PIC18F67J60-I/PT's flash, and is that enough for a TCP/IP stack with an HTTP server?
With 128 KB of flash, the PIC18F67J60-I/PT can hold a lightweight TCP/IP stack such as Microchip's TCP/IP Lite, an HTTP server with static pages, an application state machine, and EEPROM storage routines simultaneously. A minimal TCP/IP stack in PIC C typically compiles to 20–40 KB, leaving 80–100 KB for application code. This is adequate for embedded web servers delivering configuration pages, sensor readings, and control commands over a 10/100 Ethernet link.
At what minimum supply voltage can the PIC18F67J60-I/PT operate, and how does this affect Ethernet performance?
The PIC18F67J60-I/PT operates from a minimum supply voltage of 2 V at 4 MHz clock frequency. At 2 V, the Ethernet MAC and PHY interface may require separate 3.3 V regulation since standard 10/100 PHY devices typically require 3.3 V. In practice, most designs power the MCU core from a 3.3 V rail regulated from a 5 V supply, which is comfortably above the 2 V minimum and enables full 41.667 MHz clock operation for maximum TCP/IP throughput.
How does the PIC18F67J60-I/PT compare to adding an ENC28J60 external Ethernet controller to a standard PIC18 MCU?
Using the PIC18F67J60-I/PT replaces a standard PIC18 plus ENC28J60 combination by integrating the Ethernet MAC on the MCU die. This eliminates one SPI device on the bus, frees up 4 SPI pins for other peripherals, reduces PCB area by approximately 1 cm², and removes the SPI communication overhead of up to several hundred microseconds per frame that the ENC28J60 imposes. The trade-off is that the PIC18F67J60 is a specific MCU rather than a flexible add-on, so it suits designs where Ethernet is a core requirement from the start.
