PIC18F96J65-I/PF - 96KB Flash 8-bit MCU w/ Ethernet | Microchip
MPN: PIC18F96J65-I/PF ✓ Hoạt độngPIC18F96J65-I/PF Tóm tắt
What is a PIC18F Microcontroller? PIC18F is Microchip's family of high-performance 8-bit microcontrollers based on an enhanced RISC architecture with hardware multiply and a 16-bit instruction word. Within the broader taxonomy, the PIC18F sits below PIC microcontroller -> 8-bit MCU -> microcontroller -> integrated circuit -> semiconductor. The "J" suffix denotes 2.5V/3.3V operation with a 1 Mbit Flash optimized for high-pin-count, networked applications, distinguishing it from the K-series parts that run at 5V with more modern peripherals.
Key features include 96 KB self-programmable Flash with 1,000,000 erase/write cycles endurance, 3,808 bytes of SRAM, an integrated 10 Mbps Ethernet MAC and PHY, dual analog comparators, five timers, two capture/compare/PWM modules, and an enhanced USART. The device supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD), enabling field upgrades and streamlined production programming.
The PIC18J core uses a Harvard architecture with separate program and data buses, achieving 16 MIPS at 64 MHz oscillator input (4x PLL is not used here; the part uses the input clock directly). On-chip peripherals include a 10-bit ADC with up to 16 channels, hardware CRC, mTouch capacitive touch sensing, and a parallel slave port for external memory expansion. The integrated Ethernet MAC/PHY eliminates the need for an external PHY, reducing BOM cost for connected-embedded designs.
Typical applications include industrial Ethernet nodes, building automation controllers, remote sensor monitoring with TCP/IP, HVAC networked thermostats, and home automation gateways. The wide I/O count and integrated Ethernet make it especially useful for distributed control systems requiring a standards-based network interface.
Designers should note that the PIC18F96J65-I/PF operates from 2.0V to 3.6V; a 3.3V LDO is recommended for stable Ethernet PHY operation. An external 25 MHz crystal is required to drive the integrated Ethernet PLL and clock system. Decoupling capacitors should be placed within 5 mm of each power pin, and the Ethernet magnetic module must be placed within 25 mm of the RJ45 jack.

Ứng dụng tiêu biểu
PIC18F96J65-I/PF phù hợp cho 6 Áp dụngs: Industrial Ethernet Node, Building Automation Controller, Remote Sensor Monitoring with TCP/IP, Home Automation Gateway, HVAC Networked Thermostat, Industrial Serial-Ethernet Bridge.
Industrial Ethernet Node
The PIC18F96J65-I/PF's integrated 10 Mbps Ethernet MAC/PHY and 96 KB Flash eliminate the need for an external PHY, cutting BOM cost for industrial Ethernet endpoints such as Modbus-TCP nodes, EtherNet/IP gateways, or PROFINET edge devices. The 41.667 MHz CPU delivers 16 MIPS, which is sufficient for a TCP/IP lite stack plus protocol-handling logic. The 70 I/O pins accept multiple sensor inputs and actuator outputs from a single MCU. A 3.3V LDO with <50 mV ripple should power AVDD pins for clean Ethernet signaling; designers should keep the Ethernet magnetics within 25 mm of the RJ45 to meet IEEE 802.3 return-loss specs.
Được đề xuất
Building Automation Controller
Building automation systems (BAS) such as BACnet/IP thermostats, lighting controllers, and HVAC gateway nodes benefit from the PIC18F96J65-I/PF's integrated Ethernet and 70 I/O lines. The 96 KB Flash fits BACnet/IP or MODBUS-TCP stack plus application logic; 3,808 bytes RAM handles packet buffers for moderate traffic. The 2.5V/3.3V operation reduces power budget over 5V peers, important for large-building energy compliance. The MCU's industrial-grade temperature range (-40C to +85C) covers rooftop and basement enclosures without a heater.
Được đề xuất
Remote Sensor Monitoring with TCP/IP
Remote-monitoring systems (environmental sensors, vibration loggers, water-quality probes) send data over Ethernet to cloud gateways, and the PIC18F96J65-I/PF is well matched: its integrated 10 Mbps Ethernet MAC/PHY eliminates the PHY BOM, the 10-bit ADC captures up to 16 sensor channels, and the 96 KB Flash holds a TCP/IP stack plus remote firmware-update logic. The "J" core's low-power Idle and Sleep modes let the system wake on timer or external sensor interrupt, drawing <10 uA when idle.
Được đề xuất
Home Automation Gateway
Consumer home-automation gateways (Zigbee-to-IP bridges, Wi-Fi/Ethernet bridges, smart-meter aggregators) use the PIC18F96J65-I/PF as a low-cost TCP/IP termination point with sufficient Flash for an MQTT or HTTP client plus protocol-translation logic. The 70 I/O lines accept multiple sensor busses (I2C, SPI, UART) and the 41.667 MHz core services Ethernet plus sensors concurrently without dropping packets. Its 3.3V operation simplifies shared-rail designs with companion Wi-Fi modules.
Được đề xuất
HVAC Networked Thermostat
Networked HVAC thermostats require Ethernet connectivity for centralized scheduling plus local control of relays and dampers. The PIC18F96J65-I/PF's integrated 10 Mbps Ethernet MAC/PHY plus 70 I/O lines can directly drive relay matrices, triac interfaces, and NTC thermistor inputs via its 10-bit ADC. The 96 KB Flash comfortably holds the network stack plus scheduling firmware, while the -40C to +85C industrial range covers rooftop and basement installations. Power consumption is low enough to run from a small 3.3V LDO off a 24VAC wall adapter.
Được đề xuất
Industrial Serial-Ethernet Bridge
Serial-to-Ethernet bridges (RS-232/RS-485 to TCP/IP converters) are a classic application for the PIC18F96J65-I/PF: the integrated Ethernet MAC/PHY plus two EUSART modules can simultaneously drive one Ethernet port and one RS-485 port (the second USART drives a half-duplex RS-485 transceiver). 96 KB Flash holds the lightweight TCP/IP stack plus Modbus RTU-to-Modbus TCP gateway logic. The 70 I/O count exposes extra GPIOs for flow-control, mode switches, and status LEDs without a CPLD.

Ghi chú thiết kế
The PIC18F96J65-I/PF requires a clean 3.3V supply on VDD/AVDD with <50 mV ripple for reliable Ethernet PHY operation. Place a 10 uF tantalum plus a 100 nF ceramic within 5 mm of each VDD pin pair, and route AVDD through a ferrite bead from VDD if digital switching noise couples to the ADC. The Ethernet internal regulator (ENVREG, pin 100) must be bypassed with a 10 uF tantalum and 100 nF ceramic to VSS per Microchip datasheet 39931D power-supply guidelines.
Place the 25 MHz Ethernet reference crystal within 5 mm of OSCI/OSCO with trace capacitance under 3 pF, and surround the crystal area with a ground guard ring tied to VSS. The Ethernet magnetics (RJ45 integrated magnetics) must be placed within 25 mm of the TPO+/TPO- and TPI+/TPI- pins with 100-ohm differential routing and no right-angle bends, per IEEE 802.3 return-loss compliance. Keep digital signal traces (especially from RD ports) at least 5 mm away from analog signals.
The 2.5V/3.3V operating range is incompatible with 5V peripherals without a level shifter - a common pitfall when migrating firmware from a 5V PIC18F46K22 board. Forgetting to set the CONFIG register to enable the internal Ethernet regulator or to assign alternate pin functions (RD ports for PMP) will cause mysterious Ethernet link-up failures. Always confirm the CONFIG bits for OSC, BOR, WDT, and ETHREGEN match the design's requirements before locking firmware.
Estimated: at maximum CPU activity (41.667 MHz, all peripherals enabled, Ethernet transmitting), the core supply current is approximately 60 mA from VDD (datasheet 39931D DC characteristics typical values). With VDD = 3.3V, this is roughly 200 mW dissipation in the 100-pin TQFP package (theta-JA approximately 39 C/W on a 4-layer JEDEC test board), resulting in a 8C junction rise above ambient - well within the 85C industrial limit. No heatsink required.
