PIC18LF96J65-I/PT Overview
An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction per clock cycle (except branches), using separate program and data buses to allow simultaneous instruction fetch and data access. Within the broader taxonomy it sits as PIC -> microcontroller (MCU) -> embedded controller -> semiconductor IC. PIC18 devices are the high-end tier of the 8-bit PIC family, offering extended instruction set (1.5K x 16 instructions), linear program memory up to 2 MB, hardware multiplier, and rich peripheral integration compared to baseline PIC10/12/16 parts.
Key features include 70 general-purpose I/O pins, an internal oscillator, two USARTs, two MSSP (SPI/I2C) modules, two CCP modules, a 10-bit ADC with up to 16 channels, a parallel slave port, and the integrated MAC with MII/RMII interfaces for external PHY connection. Real-time hardware capabilities such as five 16-bit timers and an RTCC reduce software overhead for deterministic control loops. The Ethernet MAC is the headline differentiator, enabling single-chip TCP/IP connectivity without an external protocol controller.
The architecture combines a 16-bit instruction word with 8-bit data paths, including a hardware 8x8 multiplier and barrel shifter for arithmetic throughput. The 3808-byte SRAM supports Ethernet packet buffers plus application variables, and Flash program memory is self-programmable under software control for bootloader or field-update use cases.
Typical applications include industrial automation nodes, building automation gateways, home-control and security panels, networked instrumentation, and remote monitoring equipment. The integrated Ethernet plus rich I/O count makes the device a single-chip bridge between sensors/actuators and an IP network.
When designing with this part, plan the oscillator strategy early because Ethernet requires a precise 25 MHz or 50 MHz reference, and validate that PHY-MAC voltage rails align with the low-voltage 'LF' range. For drop-in scaling within the PIC18LF family, the 64-pin and 80-pin PIC18LF87J/J65 variants share the same peripheral set but offer fewer I/O.

Typical Applications
PIC18LF96J65-I/PT is suitable for 7 applications: Industrial Automation Ethernet Nodes, Building Automation Gateways, Home Control and Security Panels, Networked Instrumentation and Data Loggers, Remote Monitoring and Telemetry Terminals, Smart Sensor Hubs with Ethernet Uplink, Low-Volume Ethernet-Enabled Embedded Controllers.
Industrial Automation Ethernet Nodes
The PIC18LF96J65-I/PT's integrated 10 Mbps Ethernet MAC combined with 96 KB Flash and 3808-byte RAM makes it a single-chip solution for industrial automation nodes that must communicate over Modbus TCP, EtherNet/IP, or proprietary TCP/IP protocols. Its 41.667 MHz PIC core delivers enough throughput for the TCP/IP stack plus control-loop logic, while the 2.0 V-3.6 V supply range tolerates noisy 24 V industrial rails when paired with a wide-input DC-DC. The 70 GPIO pins accept multiple sensor inputs and actuator outputs without an external I/O expander.
Recommended
Building Automation Gateways
Building automation gateways require a low-power MCU with network connectivity, and the PIC18LF96J65-I/PT fits with its integrated 10 Mbps Ethernet MAC and 70 I/O pins for HVAC, lighting, and access-control peripherals. The 96 KB Flash holds BACnet/Modbus plus web-server firmware, while the 3808-byte RAM supports packet buffers. The 2.0 V-3.6 V supply range allows direct 3.3 V operation from a wall-wart supply, simplifying UL-listed product design.
Recommended
Home Control and Security Panels
Home-control and security panels benefit from the PIC18LF96J65-I/PT's integrated Ethernet MAC for cloud telemetry, 70 GPIO for keypad/zone inputs and siren outputs, and 96 KB Flash for UI logic plus TLS-aware firmware. The PIC18LF's 2.0 V-3.6 V supply simplifies PoE-powered designs when paired with a PoE PD module. The 100-TQFP package provides ample I/O without forcing PCB layers beyond two.
Recommended
Networked Instrumentation and Data Loggers
Networked data loggers need Ethernet for time-stamped upload of sensor readings, and the PIC18LF96J65-I/PT provides the integrated 10 Mbps MAC plus 10-bit ADC and 96 KB Flash for local buffering and HTTP/MQTT client stacks. The 3808-byte RAM supports TCP socket buffers, while the 41.667 MHz core sustains periodic ADC scans at sample rates up to the ADC's maximum conversion time. The 100-TQFP footprint keeps the analog/digital ground split manageable for mixed-signal accuracy.
Recommended
Remote Monitoring and Telemetry Terminals
Remote telemetry terminals (RTUs) for utility or environmental monitoring benefit from the PIC18LF96J65-I/PT's Ethernet MAC, low-voltage operation (2.0-3.6 V), and 70 I/O for multi-sensor interfaces. The 96 KB Flash fits DNP3/IEC 60870 protocol plus site logic, while the 41.667 MHz core handles scheduling and CRC. The wide industrial temperature grade (-40C to +85C) suits outdoor enclosures.
Recommended
Smart Sensor Hubs with Ethernet Uplink
Smart sensor hubs that aggregate I2C/SPI sensors and forward readings over Ethernet can rely on the PIC18LF96J65-I/PT's two MSSP modules (SPI+I2C simultaneously) and integrated 10 Mbps MAC. The 96 KB Flash fits a sensor-fusion plus TCP/IP client stack, while 3808-byte RAM handles packet assembly without external memory. The 100-TQFP package supports fan-out to many sensor daughterboards.
Recommended
Low-Volume Ethernet-Enabled Embedded Controllers
For low-volume Ethernet-enabled controllers in custom industrial equipment, the PIC18LF96J65-I/PT offers an 8-bit solution that is simpler to program than ARM and avoids RTOS overhead. Its 2.0 V-3.6 V supply range pairs with 3.3 V Ethernet PHYs without level shifters, and the 96 KB Flash holds complete application firmware plus a lightweight TCP/IP stack such as Microchip's MLA. The 100-TQFP is widely available on low-cost PCB assembly lines.

Key Differentiators
- Low-voltage 3.6 V max with integrated Ethernet MAC (vs PIC18F96J65-I/PT)
- Higher Flash density than older PIC18LF97J60 family (vs PIC18LF97J60-I/PT)
- Same footprint, more memory than PIC18LF8720 (vs PIC18LF8720-I/PT)
Design Notes
The PIC18LF96J65-I/PT requires a clean 3.3 V rail for Ethernet MAC operation; place a 10 uF bulk capacitor plus 0.1 uF decoupling on each VDD pin pair. The 'LF' device draws higher current at 41.667 MHz (around 30 mA typical) so budget DC-DC capacity accordingly. For battery applications, leverage the deep-sleep modes (under 1 uA) and wake on Ethernet packet via external PHY interrupt, since the integrated MAC itself does not provide wake-on-LAN.
Route the 25 MHz or 50 MHz Ethernet reference clock trace as a short, impedance-controlled 50 ohm line and keep it away from switching DC-DC nodes. The 100-TQFP (14x14 mm) package leaves adequate room for a four-layer PCB with a solid ground plane under the MCU. Place the external PHY within 50 mm of the MAC MII/RMII pins to minimize skew.
Do not exceed 3.6 V on VDD or 5 V tolerance will not apply to this 'LF' part (use PIC18F96J65-I/PT instead). The integrated MAC requires an external PHY chip such as the LAN8720A or DP83848; PCB layout errors here are the most common reason Ethernet designs fail EMC. The MCLR pin must have a 10 kohm pull-up to VDD or the device will not start; verify RC delay on MCLR matches datasheet requirements.
Estimated: at 3.3 V, 41.667 MHz, and full I/O load, the PIC18LF96J65-I/PT dissipates about 100 mW. With a theta_JA of approximately 50 C/W for the 100-TQFP (14x14 mm), junction temperature rises only about 5 C above ambient, well within the -40C to +85C industrial range. No heatsink is required under normal conditions; however, enclosing the board in a sealed housing reduces thermal margin.
