PIC18F67J60-I/PT Overview
An 8-bit microcontroller is a single-chip processor with an 8-bit data path, on-chip Flash program memory, RAM, and integrated peripherals. It sits in the hierarchy: microcontroller -> embedded microprocessor -> integrated circuit -> semiconductor. The PIC18 family extends this with a RISC architecture, hardware multiply, and C-friendly peripherals, while the PIC18F67J60 sub-family adds an embedded Ethernet controller that integrates the MAC, PHY, and pulse transformers, making it a single-chip solution for networked embedded designs.
Key features include 128 KB Flash organized as 64K x 16 words, 12 KB SRAM, an integrated 10BASE-T Ethernet MAC/PHY with HP Auto-MDIX support, 54 digital I/O pins, two USARTs, two MSSP (SPI/I2C) ports, two CCP/ECCP modules, a 10-channel 10-bit ADC, and one 8-bit and three 16-bit timers. The Ethernet peripheral is the defining element: it eliminates the need for an external PHY or MAC chip, reducing BOM cost and PCB area in remote-monitoring nodes.
Internally, the part uses a Harvard RISC core with a hardware multiplier, runs from an internal 8 MHz oscillator (pll-able to 41.667 MHz), and supports in-circuit programming via ICSP. The Flash and configuration bits are accessed through Microchip's standard MPLAB development flow, and the on-chip Ethernet module uses an internal DMA engine to offload packet handling from the CPU.
Typical applications include Industrial Automation (Modbus/TCP nodes, sensor gateways), Building Automation (BACnet/IP thermostats, lighting controllers), Remote Monitoring (utility metering, asset tracking), Embedded Web Servers, and Home Appliance Networking. The wide 4.2 V to 5.5 V supply range also makes it tolerant of unregulated 5 V wall adapters.
When designing with this part, ensure the integrated Ethernet PHY is matched to a 1:1 isolation transformer and RJ45 with HP Auto-MDIX wiring to preserve the auto-crossover feature. The 64-pin TQFP footprint requires careful PCB routing of the differential Ethernet pair to maintain 100-ohm differential impedance over a continuous reference plane.

Typical Applications
PIC18F67J60-I/PT is suitable for 6 applications: Industrial Automation Gateway, Building Automation Controller, Remote Monitoring and Telemetry, Embedded Web Server, Home Appliance Networking, Point-of-Sale Terminal.
Industrial Automation Gateway
The PIC18F67J60-I/PT is well suited to industrial automation gateways such as Modbus/TCP nodes and sensor aggregation bridges. The integrated 10BASE-T MAC/PHY with HP Auto-MDIX eliminates the external Ethernet controller, reducing BOM and PCB area in DIN-rail enclosures. The 12 KB SRAM supports Microchip's TCP/IP Lite stack, while 128 KB of Flash accommodates protocol translation logic. The 54 digital I/O pins handle multiple sensor interfaces, and the -40C to +85C industrial range tolerates factory environments.
Recommended
Building Automation Controller
For BACnet/IP thermostats, lighting controllers, and HVAC monitoring nodes, the PIC18F67J60-I/PT provides a single-chip networked solution. Its 4.2 V to 5.5 V supply allows direct 5 V wall-adapter powering, eliminating the need for an additional LDO. The 41.667 MHz (10 MIPS) core processes BACnet/IP application layers and scheduling logic, while the two USARTs and two MSSP ports interface to local RS-485 sensor networks. The 10-channel 10-bit ADC supports multiple analog sensor inputs from temperature, humidity, and airflow sensors.
Recommended
Remote Monitoring and Telemetry
The PIC18F67J60-I/PT enables remote monitoring of utility meters, asset trackers, and environmental sensors via Ethernet. The 10BASE-T PHY provides reliable wired connectivity to plant SCADA systems, while the 128 KB Flash stores TCP/IP stack, SNMP agent, and data-logging firmware. The wide 4.2 V to 5.5 V supply tolerance accommodates long cable runs with voltage drop, and the integrated HP Auto-MDIX allows direct connection to either a switch or a PC crossover without manual configuration.
Recommended
Embedded Web Server
Designers building embedded web servers for equipment configuration and diagnostics rely on the PIC18F67J60-I/PT's integrated Ethernet plus 128 KB Flash. The on-chip MAC/PHY plus generous program memory allows hosting of HTTP servers with custom HTML interfaces for setting up and monitoring industrial equipment. The 12 KB RAM supports TCP socket buffers, and the two ECCP/PWM modules can control motor speed or LED brightness directly from the web interface without intermediate logic.
Recommended
Home Appliance Networking
Connected home appliances such as smart refrigerators, washers, and HVAC controllers benefit from the PIC18F67J60-I/PT's single-chip networking. The HP Auto-MDIX feature lets designers ignore whether a home router uses crossover wiring, simplifying end-user installation. The 41.667 MHz core handles light TCP/IP traffic from companion mobile apps, while the 54 I/O pins drive user interfaces, sensors, and motor control stages on the appliance main board.
Recommended
Point-of-Sale Terminal
Compact point-of-sale and kiosk terminals use the PIC18F67J60-I/PT as their network and main control MCU. The integrated Ethernet enables IP-based payment processing and remote firmware updates over store networks. The 128 KB Flash holds graphical UI code, while the multiple USART/MSSP peripherals connect to barcode scanners, receipt printers, and secure payment modules. The industrial temperature range supports unattended kiosks and outdoor payment stations.

Key Differentiators
- Single-chip Ethernet MAC + PHY with HP Auto-MDIX (vs PIC18F67J10-I/PT)
- Higher 128 KB Flash density vs 64 KB variant (vs PIC18F66J60-I/PT)
- Two MSSP ports for SPI + I2C simultaneously (vs PIC18F6720-I/PT)
Design Notes
Route the integrated Ethernet differential pair (TP+/- on the chip pins) over a continuous ground reference plane with 100-ohm differential impedance. Keep the trace length under 50 mm and avoid splits in the ground plane beneath the pair to maintain signal integrity for 10BASE-T operation; place the 1:1 isolation transformer within 25 mm of the PHY pins.
Estimated: at 41.667 MHz and 5 V VDD with all peripherals enabled, the device typically draws ~70 mA. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin and a bulk 10 uF tantalum cap at the regulator output; the Ethernet PHY benefits from an additional 10 uF + 100 nF LC filter near the analog supply pin to suppress switching noise coupling into the line drivers.
The 'J' in PIC18F67J60 indicates a 5V-tolerant I/O design that cannot operate below 4.2 V - connecting this part to a 3.3 V rail will result in undefined oscillator behavior. Do not substitute a PIC18F67J10 design without re-validating the supply and crystal circuit. Also ensure the CONFIG bits set the correct oscillator mode and disable the JTAG pins if not used, otherwise PORTB will be unavailable.
Compliance Information
RoHS and REACH compliant per Microchip product documentation. Not AEC-Q100 qualified - this part targets industrial-grade applications rather than automotive. Lead-free (Pb-free) terminations confirmed.
