PIC18F67J60T-I/PT - 8-Bit MCU w/ Ethernet, 128KB Flash | Microchip
MPN: PIC18F67J60T-I/PT ✓ نشطPIC18F67J60T-I/PT نظرة عامة
A microcontroller (MCU) is a compact integrated circuit that combines a CPU core, program memory, RAM, and peripheral interfaces on a single die. The PIC18F family uses Microchip's enhanced Harvard RISC architecture with a 16-bit instruction word and 8-bit data path, optimized for deterministic real-time control. PIC18F "J" devices add an internal voltage regulator so the core runs from a regulated 2.5V/1.8V rail while the I/O pads interface directly to 3.3V systems. This hierarchy places the PIC18F67J60 in the PIC18 family, within the 8-bit MCU category, and ultimately inside the broader microcontroller > embedded processor > semiconductor taxonomy.
Key features include an integrated 10BASE-T Ethernet controller with on-chip PHY and MAC, 54 digital I/O pins, four 16-bit timers, two CCP and three ECCP modules, dual comparators with input multiplexing, a 12-bit ADC (shared with the 10-bit variant family) and hardware cryptographic acceleration via the on-chip AES engine in select firmware libraries. The 128KB Flash supports self-programming and ICSP, and 3.8KB of RAM plus 1KB of dedicated Ethernet buffer RAM are sufficient for TCP/IP stacks such as Microchip's TCP/IP Lite or uIP. The wide operating range and integrated PHY eliminate external Ethernet components, reducing BOM cost by approximately $1.50 per node.
Architecturally, the PIC18F67J60 uses an 8-bit RISC engine with hardware multiply, a 16-bit wide instruction fetch and a 32-level deep hardware stack. The integrated Ethernet block follows IEEE 802.3 10BASE-T, providing MAC, PHY and 10BASE-T magnetics interface in silicon; designers add only an isolation transformer and RJ-45 jack. The internal 2.5V LDO allows single-supply 3.3V operation, while separate analog and digital supply pins support mixed-signal designs.
Typical applications include industrial automation (Modbus/TCP and EtherNet/IP gateways), building automation (BACnet/IP and HVAC controllers), remote sensor monitoring over Ethernet, IP-connected home appliances, and low-cost web/SCADA server nodes. Designers should note the integrated Ethernet MAC/PHY requires a unique MAC address (factory-programmed option available) and the part supports Microchip's free TCP/IP stack with example projects for HTTP, SMTP and DHCP servers.

Building Automation Controller
The PIC18F67J60T-I/PT suits BACnet/IP and HVAC controllers because its on-chip 10BASE-T PHY simplifies wall-mount and rooftop unit designs that need a single Ethernet cable for both power (PoE-ready) and data. The 128 KB Flash stores BACnet/IP objects plus scheduling logic while the 3.8 KB RAM plus 1 KB dedicated Ethernet buffer prevents TCP/IP stack contention during peak traffic. Per the Microchip datasheet, the 54 I/O connect to 0-10V actuator drivers, thermistor inputs and triac control lines. Operating from -40C to +85C, the part survives mechanical-room environments.

The PIC18F67J60T-I/PT powers IP-connected data loggers because the integrated 10BASE-T MAC/PHY plus 128 KB Flash and Microchip's TCP/IP Lite stack allow direct FTP push of CSV logs to a network share every minute, without an external network processor. The 54 I/O plus 12-bit ADC (shared with the 10-bit variant) capture up to 13 analog channels plus digital triggers. Per the Microchip datasheet, 3.8 KB RAM plus 1 KB Ethernet buffer prevent stack overrun during FTP transfers. The TQFP-64 industrial -40C to +85C range suits unattended cabinet installations.

ملاحظات التصميم
The PIC18F67J60T-I/PT requires a single 3.3V rail on VDD (2.0V-3.6V range). The internal 2.5V LDO powers the core, so no separate 2.5V supply is needed. Place a 100nF decoupling capacitor on each VDD pin and a single 10uF bulk capacitor near the supply entry point. Estimated: at full 41.667 MHz CPU load the core current is approximately 15 mA, plus 100 mA peak for Ethernet activity. Use a low-noise LDO such as the MCP1700 or AP2112 with the standard 1uF ceramic output capacitor.
The integrated 10BASE-T Ethernet MAC/PHY has dedicated analog pins (TPIN, TPOUT, RBIAS, ETHREF). Place the 12.4k RBIAS resistor and 1.9k ETHREF resistor within 5mm of the respective pins with a quiet ground via. Per Microchip reference designs, keep the TPOUT traces at 100 ohm differential and short (under 25mm). Route AVSS/AVDD traces separately from digital VDD/VSS to prevent digital switching noise from coupling into the analog Ethernet signals.
Each PIC18F67J60 needs a unique MAC address. Program a factory MAC address via Microchip's programming service, or store a custom MAC in the Flash user ID area and copy it to Ethernet registers at startup. Estimated: a 6-byte MAC may be pre-programmed in the last 6 bytes of Flash configuration memory. Do not skip the MAC address initialization, or the Ethernet peripheral will fail to transmit or receive.
For reliable 10BASE-T operation, use a 1:1 isolation transformer (such as the Pulse H1102 or equivalent) rated for 10Mbps. Place the transformer within 25mm of the TPOUT and TPIN pins. The transformer secondary side connects to the RJ-45 jack with 75 ohm center-tapped termination per IEEE 802.3. Per Microchip reference designs, do not omit the Bob Smith termination on the unused RJ-45 lines, or radiated emissions will fail FCC Class B.
