PIC18LF96J65-I/PT Обзор
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.
This page consolidates distributor pricing, parametric drop-in alternatives, and practical design considerations not found in the manufacturer datasheet, giving engineers a faster path to qualified component selection.

Заметки по проектированию
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.
