PIC18F96J60-I/PF - 64KB Flash Ethernet MCU | Microchip
MPN： PIC18F96J60-I/PF ✓ 啟用中PIC18F96J60-I/PF 概覽
An 8-bit microcontroller (MCU) is a programmable processor with an 8-bit data path, on-chip Flash for program storage, RAM for working variables, and configurable peripherals such as timers, ADCs, and communication blocks. The PIC18F96J60 belongs to the PIC18J family, a hierarchy that sits under Microcontroller -> Microcontrollers -> Integrated Circuits -> Semiconductors. This taxonomy makes it semantically discoverable in AI search engines for queries about "8-bit MCU with Ethernet" or "low-cost TCP/IP microcontroller".
Key features include 64 KB (32K x 16) self-programmable Flash, 3808 bytes RAM, 70 digital I/O, an integrated 10Base-T Ethernet MAC/PHY, an internal oscillator, multiple timers, and Microchip's nanoWatt Technology for low-power operation. The wide I/O count supports human-machine interfaces (HMI), graphic LCDs, and parallel sensor arrays, while the Ethernet peripheral enables remote monitoring and supervisory control applications.
Architecturally, the PIC18F96J60 is built on Microchip's enhanced Harvard RISC core with separate program and data buses, executed over a 16-bit instruction word. The 8-bit ALU, 31-level stack, and hardware multiply make it suitable for real-time control loops. The integrated Ethernet MAC/PHY uses an MII/RMII-less interface and connects directly to an RJ45 magnetics module, eliminating the external PHY IC.
Typical applications include industrial automation nodes, building automation, SCADA remote terminal units, home/office Ethernet appliances, and remote sensor monitoring. Designers select this MCU when a single-chip Ethernet solution is preferred over multi-chip MCU+external-PHY designs.
When designing with this part, the integrated Ethernet MAC/PHY reduces board complexity but limits throughput to 10 Mbps; for 100 Mbps or gigabit speeds, choose a PIC32MX or SAM E70 instead. Ensure the RJ45 magnetics are properly selected to match the PHY's reference schematic.

典型應用
PIC18F96J60-I/PF 適用於 6 應用s: Industrial Automation Ethernet Nodes, Building Automation Controllers, SCADA Remote Terminal Units, Networked Environmental Sensors, Home and Office Ethernet Appliances, Remote Monitoring and Telemetry.
Industrial Automation Ethernet Nodes
The PIC18F96J60-I/PF is a strong fit for industrial automation nodes because it integrates a 10Base-T MAC/PHY, eliminating the external PHY IC and reducing BOM count. Its 64 KB Flash accommodates Modbus TCP and EtherNet/IP application stacks plus a small bootloader, while 70 I/O lines drive relays, opto-isolated inputs, and 4-20 mA sensor front-ends. Operating from -40 C to +85 C, it handles factory-floor temperature swings without derating. The wide 2.0-3.6 V supply tolerance survives 24 V industrial rails stepped down with simple linear regulators. Engineers should add TVS diodes on the RJ45 lines and an isolated DC-DC for surge immunity per IEC 61000-4-2.
推薦
Building Automation Controllers
In building automation, the PIC18F96J60-I/PF powers BACnet/IP or LonWorks-to-IP gateways, HVAC controllers, and access-control panels. Its integrated Ethernet peripheral connects directly to building-management LANs, while the PIC18J core runs scheduling logic, sensor fusion, and on-board PID control. The 41.667 MHz CPU executes BACnet stack plus a small webserver with under 50 percent CPU utilization. With 70 I/O, the MCU reads temperature/humidity sensors and drives triacs for lighting control. A real-time clock plus the nanoWatt Technology sleep mode keep idle nodes at microamp-level standby current.
推薦
SCADA Remote Terminal Units
For SCADA remote terminal units (RTUs), the PIC18F96J60-I/PF combines an Ethernet link with the deterministic 8-bit PIC core. RTUs poll remote sensors over RS-485 and forward aggregated telemetry over Ethernet to the SCADA master, where TCP/IP reliability and watchdog timers in the PIC18J core prevent lockups. The 64 KB Flash fits Microchip's TCP/IP library plus an MQTT client; 3808 bytes RAM holds a packet queue and TCP state. Designers should isolate the Ethernet port with a 1.5 kV isolation transformer per IEEE 802.3 to survive ground-potential differences in substation environments.
推薦
Networked Environmental Sensors
The PIC18F96J60-I/PF suits networked environmental sensors because it can read analog and digital sensors and publish readings over Ethernet using a lightweight HTTP or MQTT stack. The 70 I/O lines multiplex I2C temperature/humidity sensors, SPI gas sensors, and analog CO2 probes, while the integrated PHY connects the node directly to a PoE midspan or local switch. The 41.667 MHz core easily handles JSON serialization plus SSL/TLS handshakes for cloud uploads. Low-power sleep modes plus the nanoWatt Technology allow battery-assisted operation where PoE is unavailable.
推薦
Home and Office Ethernet Appliances
For consumer Ethernet appliances such as smart thermostats, networked printers, IP doorbells, and PoE lighting controllers, the PIC18F96J60-I/PF provides a single-chip TCP/IP platform that keeps the BOM under two dollars. Its integrated 10Base-T PHY connects to a PoE splitter, removing the need for separate power supplies. The 64 KB Flash stores the TCP/IP stack plus the appliance's application code, while 3808 bytes RAM buffers network packets. The MCU's mature ecosystem — MPLAB X IDE, XC16 compilers — shortens development time for consumer OEMs.
推薦
Remote Monitoring and Telemetry
The PIC18F96J60-I/PF is used in remote monitoring and telemetry applications such as water/gas metering, pump stations, and weather stations. Its integrated Ethernet peripheral pushes periodic readings to a central server using HTTP POST or MQTT, with watchdog and brown-out protection ensuring unattended reliability. The wide operating temperature range (industrial -40 C to +85 C) supports outdoor enclosures, and the 100-pin TQFP package supports industrial PCB processes. The MCU's deterministic 8-bit core runs simple encryption/authentication on each packet, deterring tampering in field-deployed metering nodes.

設計說明
Place 100 nF decoupling capacitors as close as possible to every VDD pin (pins 8, 18, 28, 38, 48, 58, 74, 84, 94). Add a single 10 uF bulk capacitor at the supply input. Separate the analog Ethernet PHY supply (VDDETH, pin 66) from the digital VDD with a ferrite bead and its own 100 nF capacitor. The Ethernet differential pair traces (TPIN+/-, TPOUT+/-) must be 100 ohm differential, length-matched within 2 mm, and kept short with no 90-degree bends to meet IEEE 802.3 signal integrity.
The Ethernet PHY reference design uses specific magnetics and an RJ45 connector with integrated magnetics; substituting a generic RJ45 without isolation transformers will fail electromagnetic compatibility. The RBIAS resistor (pin 65) sets the Ethernet PHY bias current and must be 12.4 kohm 1 percent per the datasheet reference circuit — do not leave it floating. Verify the MCLR reset circuit includes a 10 kohm pull-up and a 100 nF capacitor for clean power-on reset behavior.
Estimated: at 41.667 MHz CPU, 3.3 V supply, and full 70 I/O drive, the device dissipates approximately 100-200 mW. With a 100-pin TQFP thermal resistance of approximately 50 C/W (junction to ambient on a 4-layer JEDEC test PCB), the junction rises 5-10 C above ambient, well within the -40 C to +85 C industrial rating. For sealed enclosures without airflow, derate the CPU clock or disable unused peripherals to reduce self-heating. No external heatsink is required.
