Microchip PIC18F65J10T-I/PT: A Comprehensive Technical Overview

The Microchip PIC18F65J10T-I/PT stands as a prominent member of the PIC18F J-series family, engineered to deliver a robust blend of performance, connectivity, and power efficiency for embedded control applications. This 8-bit microcontroller, built on Microchip's enhanced PIC18 architecture, is particularly suited for complex industrial, automotive, and consumer applications where a rich peripheral set and reliable operation are paramount.

Housed in a 64-pin TQFP package, this device is designed for space-constrained PCB designs requiring a high number of I/O lines. Its core operates at a maximum frequency of 48 MHz, achieving a performance level of 12 MIPS. A significant architectural advantage is the inclusion of a 16-bit wide instruction bus and an 8-bit wide data bus, which enhances throughput by allowing concurrent instruction fetch and data access.

A cornerstone of its design is the extensive memory configuration. It features 128 KB of self-read/write capable Flash program memory and 3808 bytes of RAM. This substantial non-volatile memory supports large application codes and data tables, while the generous RAM is crucial for handling complex data processing tasks and real-time operating systems.

The peripheral set integrated into this MCU is exceptionally comprehensive, making it a true System-on-Chip (SoC) solution. Key communication interfaces include:

Ethernet MAC (EMAC) with a dedicated DMA controller for networked applications.

2 x CAN (Controller Area Network) 2.0B modules, essential for robust automotive and industrial network communications.

2 x USART, 2 x SPI, and 2 x I²C modules for interfacing with a vast array of serial peripherals, sensors, and other microcontrollers.

For analog needs, the device integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, allowing for precise monitoring of multiple analog signals. Furthermore, it includes 2 analog comparators for quick, non-digital signal comparisons.

Development and debugging are streamlined through the In-Circuit Serial Programming™ (ICSP™) and In-Circuit Debug (ICD) capabilities, allowing for easy firmware updates and real-time troubleshooting without removing the chip from the circuit.

Operating from a 2.0V to 3.6V supply, the PIC18F65J10T-I/PT is optimized for low-power operation. It features multiple software-selectable power-saving modes, including Idle and Sleep, which drastically reduce current consumption in battery-sensitive applications.

ICGOODFIND: The PIC18F65J10T-I/PT is a feature-dense, high-performance 8-bit microcontroller. Its standout features include integrated Ethernet and dual CAN bus controllers, a large memory footprint, and a rich suite of analog and digital peripherals.
